As a Python developer, I love using Django for web development. Its built-in features and clear code structure make building scalable and robust web applications fast and efficient. In fact, I used Django to build my own web app for Python testing and training.

Here’s how you can install Django:

pip install django

Alternatively, you may use any of the following commands to install django, depending on your concrete environment. One is likely to work!

 If you have only one version of Python installed:

pip install django  If you have Python 3 (and, possibly, other versions) installed:

pip3 install django  If you don't have PIP or it doesn't work

python -m pip install django

python3 -m pip install django  If you have Linux and you need to fix permissions (any one):

sudo pip3 install django

pip3 install django --user  If you have Linux with apt

sudo apt install django  If you have Windows and you have set up the py alias

py -m pip install django  If you have Anaconda

conda install -c anaconda django  If you have Jupyter Notebook

!pip install django

!pip3 install django

Let’s dive into the installation guides for the different operating systems and environments!

How to Install Django on Windows?

To install the updated Django framework on your Windows machine, run the following code in your command line or Powershell:

• python3 -m pip install --upgrade pip
• python3 -m pip install --upgrade django

Here’s the code for copy&pasting:

python3 -m pip install --upgrade pip

python3 -m pip install --upgrade django

I really think not enough coders have a solid understanding of PowerShell. If this is you, feel free to check out the following tutorials on the Finxter blog.

How to Install Django on Mac?

Open Terminal (Applications/Terminal) and run:

• xcode-select -install (You will be prompted to install the Xcode Command Line Tools)
• sudo easy_install pip
• sudo pip install django
• pip install django

As an alternative, you can also run the following two commands to update pip and install the Django library:

python3 -m pip install --upgrade pip

python3 -m pip install --upgrade django

These you have already seen before, haven’t you?

How to Install Django in PyCharm?

The simplest way to install Django in PyCharm is to open the terminal tab and run the pip install django command.

This is shown in the following code:

pip install django

Here’s a screenshot of the two steps:

1. Open Terminal tab in Pycharm
2. Run pip install django in the terminal to install Django in a virtual environment.

As an alternative, you can also search for Django in the package manager.

However, this is usually an inferior way to install packages because it involves more steps.

How to Install Django in Anaconda?

You can install the Django package with Conda using the command conda install -c anaconda django in your shell or terminal.

Like so:

 conda install -c anaconda django 

This assumes you’ve already installed conda on your computer. If you haven’t check out the installation steps on the official page.

How to Install Django in VSCode?

You can install Django in VSCode by using the same command pip install django in your Visual Studio Code shell or terminal.

pip install django

If this doesn’t work — it may raise a No module named 'django' error — chances are that you’ve installed it for the wrong Python version on your system.

To check which version your VS Code environment uses, run these two commands in your Python program to check the version that executes it:

import sys

print(sys.executable)

The output will be the path to the Python installation that runs the code in VS Code.

Now, you can use this path to install Django, particularly for that Python version:

/path/to/vscode/python -m pip install django

Wait until the installation is complete and run your code using django again. It should work now!

When managing events, the date and time come into the picture. So, the calendar component is the best to render events in a viewport. It is convenient compared to other views like card-view or list-view.

This example uses the JavaScript library FullCalendar to render and manage events. The events are from the database by using PHP and MySQL.

The following script gives you a simple event management system in PHP with AJAX. The AJAX handlers connect the PHP endpoint to manage events with the database.

In a previous tutorial, we have seen how to create a PHP event management system with Bootstrap.

Step 1: Create an HTML base with the FullCalendar library

The client-side script has the HTML with the required dependencies. This HTML uses CDN to import the JS and CSS. It uses the following libraries

1. FullCalendar.
2. MomentJS.
3. jQuery and jQuery UI.

It has an empty DIV target that will display the calendar UI after initiating the FullCalendar JavaScript library class.

index.php

<!DOCTYPE html>

<html>

<head>

<title>Event management in php</title> <script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.22.2/moment.js"></script>

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js" type="text/javascript"></script>

<script src="https://cdnjs.cloudflare.com/ajax/libs/jqueryui/1.12.1/jquery-ui.min.js"></script>

<script src="https://cdnjs.cloudflare.com/ajax/libs/fullcalendar/3.9.0/fullcalendar.min.js"></script>

<script src="https://cdnjs.cloudflare.com/ajax/libs/fullcalendar/3.9.0/locale-all.js"></script>

<link href="https://cdnjs.cloudflare.com/ajax/libs/fullcalendar/3.9.0/fullcalendar.min.css" rel="stylesheet">

<link rel="stylesheet" href="//code.jquery.com/ui/1.13.2/themes/base/jquery-ui.css">

<link rel="stylesheet" href="assets/css/style.css">

<link rel="stylesheet" href="assets/css/form.css">

<script src="assets/js/event.js"></script>

<style>

.btn-event-delete { font-size: 0.85em; margin: 0px 10px 0px 5px; font-weight: bold; color: #959595;

}

</style>

</head> <body> <div class="phppot-container"> <h2>Event management in php</h2> <div class="response"></div> <div class="row"> <input type="text" name="filter" id="filter" placeholder="Choose date" /> <button type="button" id="button-filter" on‌Click="filterEvent();">Filter</button> </div> <div class="row"> <div id='calendar'></div> </div> </div>

</body>

</html>

Step 2: Create MySQL Structure in phpMyAdmin

This example creates a persistent event management system in PHP. The newly created or modified event data are permanently stored in the database.

This script has the CREATE STATEMENT and indexes of the tbl_events database. Do the following steps to set up this database in a development environment.

1. Create a database and import the below SQL script into it.
2. Configure the newly created database in config/db.php of this project.

Database script

sql/structure.sql

--

-- Database: `full_calendar`

-- -- -------------------------------------------------------- --

-- Table structure for table `tbl_events`

-- CREATE TABLE `tbl_events` ( `id` int(11) NOT NULL, `title` varchar(255) CHARACTER SET utf8 COLLATE utf8_bin DEFAULT NULL, `start` date DEFAULT NULL, `end` date DEFAULT NULL

) ENGINE=InnoDB DEFAULT CHARSET=latin1; --

-- Indexes for dumped tables

-- --

-- Indexes for table `tbl_events`

--

ALTER TABLE `tbl_events` ADD PRIMARY KEY (`id`); --

-- AUTO_INCREMENT for dumped tables

-- --

-- AUTO_INCREMENT for table `tbl_events`

--

ALTER TABLE `tbl_events` MODIFY `id` int(11) NOT NULL AUTO_INCREMENT;

Database configuration

db.php

<?php

$conn = mysqli_connect("localhost", "root", "", "full_calendar"); if (! $conn) { echo "Failed to connect to MySQL: " . mysqli_connect_error();

}

?>

Step 3: Initiate Fullcalendar and create listeners to manage events

This section initiates the JavaScript calendar library with suitable settings. For example, the below script enables the following directives to allow mouse events to make changes in the calendar.

1. editable – It will enable event editing on the calendar by switching it on.
2. droppable – It supports event drag and drops to change the date.
3. eventResize – It supports inline extending or reducing the event period by resizing.
4. eventLimit – It allows limiting the number of events displayed on a date instance.
5. displayEventTime – It shows event time if added.

The Fullcalendar property “events” specifies the array of events rendered download. In this example, it has the PHP endpoint URL to read calendar events dynamically from the database.

This script maps the calendar event’s select, drag, drop, and resize with the defined AJAX handlers.

$(document).ready(function() { var calendar = $('#calendar').fullCalendar({ editable: true, eventLimit: true, droppable: true, eventColor: "#fee9be", eventTextColor: "#232323", eventBorderColor: "#CCC", eventResize: true, header: { right: 'prev, next today', left: 'title', center: 'listMonth, month, basicWeek, basicDay' }, events: "ajax-endpoint/fetch-calendar.php", displayEventTime: false, eventRender: function(event, element) { element.find(".fc-content").prepend("<span class='btn-event-delete'>X</span>"); element.find("span.btn-event-delete").on("click", function() { if (confirm("Are you sure want to delete the event?")) { deleteEvent(event); } }); }, selectable: true, selectHelper: true, select: function(start, end, allDay) { var title = prompt('Event Title:'); if (title) { var start = $.fullCalendar.formatDate(start, "Y-MM-DD HH:mm:ss"); var end = $.fullCalendar.formatDate(end, "Y-MM-DD HH:mm:ss"); addEvent(title, start, end); calendar.fullCalendar('renderEvent', { title: title, start: start, end: end, allDay: allDay }, true ); } calendar.fullCalendar('unselect'); }, eventClick: function(event) { var title = prompt('Event edit Title:', event.title); if (title) { var start = $.fullCalendar.formatDate(event.start, "Y-MM-DD HH:mm:ss"); var end = $.fullCalendar.formatDate(event.end, "Y-MM-DD HH:mm:ss"); editEvent(title, start, end, event); } }, eventDrop: function(event) { var title = event.title; if (title) { var start = $.fullCalendar.formatDate(event.start, "Y-MM-DD HH:mm:ss"); var end = $.fullCalendar.formatDate(event.end, "Y-MM-DD HH:mm:ss"); editEvent(title, start, end, event); } }, eventResize: function(event) { var title = event.title; if (title) { var start = $.fullCalendar.formatDate(event.start, "Y-MM-DD HH:mm:ss"); var end = $.fullCalendar.formatDate(event.end, "Y-MM-DD HH:mm:ss"); editEvent(title, start, end, event); } } }); $("#filter").datepicker();

});

function addEvent(title, start, end) { $.ajax({ url: 'ajax-endpoint/add-calendar.php', data: 'title=' + title + '&start=' + start + '&end=' + end, type: "POST", success: function(data) { displayMessage("Added Successfully"); } });

} function editEvent(title, start, end, event) { $.ajax({ url: 'ajax-endpoint/edit-calendar.php', data: 'title=' + title + '&start=' + start + '&end=' + end + '&id=' + event.id, type: "POST", success: function() { displayMessage("Updated Successfully"); } });

} function deleteEvent(event) { $('#calendar').fullCalendar('removeEvents', event._id); $.ajax({ type: "POST", url: "ajax-endpoint/delete-calendar.php", data: "&id=" + event.id, success: function(response) { if (parseInt(response) > 0) { $('#calendar').fullCalendar('removeEvents', event.id); displayMessage("Deleted Successfully"); } } });

}

function displayMessage(message) { $(".response").html("<div class='success'>" + message + "</div>"); setInterval(function() { $(".success").fadeOut(); }, 5000);

} function filterEvent() { var filterVal = $("#filter").val(); if (filterVal) { $('#calendar').fullCalendar('gotoDate', filterVal); $("#filter").val(""); }

}

Step 4: Create AJAX endpoints to create, render and manage event data

This section shows the PHP code for the AJAX endpoint. The Fullcalendar callback handlers call these endpoints via AJAX.

This endpoint receives the event title, start date, and end date. It processes the requested database operation using the received parameters.

ajax-endpoint/fetch-calendar.php

<?php

require_once "../config/db.php"; $json = array();

$sql = "SELECT * FROM tbl_events ORDER BY id"; $statement = $conn->prepare($sql);

$statement->execute();

$dbResult = $statement->get_result(); $eventArray = array();

while ($row = mysqli_fetch_assoc($dbResult)) { array_push($eventArray, $row);

}

mysqli_free_result($dbResult); mysqli_close($conn);

echo json_encode($eventArray);

?>

ajax-endpoint/add-calendar.php

<?php

require_once "../config/db.php"; $title = $_POST['title'];

$start = $_POST['start'];

$end = $_POST['end'];

$statement = $conn->prepare('INSERT INTO tbl_events (title,start,end) VALUES (?,?,?)');

$statement->bind_param('sss', $title, $start, $end);

$rowResult = $statement->execute();

if (! $rowResult) { $result = mysqli_error($conn);

}

?>

ajax-endpoint/edit-calendar.php

<?php

require_once "../config/db.php"; $id = $_POST['id'];

$title = $_POST['title'];

$start = $_POST['start'];

$end = $_POST['end'];

$statement = $conn->prepare('UPDATE tbl_events SET title = ?, start= ?, end=? WHERE id = ?');

$statement->bind_param('sssi', $title, $start, $end, $id);

$rowResult = $statement->execute();

mysqli_close($conn);

?>

ajax-endpoint/delete-calendar.php

<?php

require_once "../config/db.php"; $id = $_POST['id'];

$statement = $conn->prepare('DELETE from tbl_events WHERE id= ?');

$statement->bind_param('i', $id);

$rowResult = $statement->execute();

echo mysqli_affected_rows($conn);

mysqli_close($conn);

?>

I have a problem. I’m addicted to OpenAI. Every day I find new exciting ways to use it. It’s like somebody gave me a magic stick and I use it for stupid things like cleaning the kitchen. But I cannot help it! So, how to create images with OpenAI in Python? Easy, follow these four steps!

Step 1: Install the OpenAI Python Library

The first step to using OpenAI’s DALL·E in Python is to install the OpenAI Python library. You can do this using pip, a package manager for Python.

Open your terminal and enter the following command:

pip install openai

I have written a whole tutorial on this topic in case this doesn’t work instantly.

Recommended: How to Install OpenAI in Python?

Step 2: Create an OpenAI API Key

OpenAI is not free for coders — but it’s almost free. I only pay a fraction of a cent for a request, so no need to be cheap here.

Visit the page https://platform.openai.com/account/api-keys and create a new OpenAI key you can use in your code. Copy&paste the API key because you’ll need it in your coding project!

Step 3: Authenticate with OpenAI API Key

Next, you’ll need to authenticate with OpenAI’s API key. You can do this by importing the openai_secret_manager module and calling the get_secret() function. This function will retrieve your OpenAI API key from a secure location, and you can use it to authenticate your API requests.

import openai_secret_manager

import openai secrets = openai_secret_manager.get_secret("openai") # Authenticate with OpenAI API Key

openai.api_key = secrets["api_key"]

If this sounds too complex, you can also use the following easier code in your code script to try it out:

import openai # Authenticate with OpenAI API Key

openai.api_key = 'sk-...'

The disadvantage is that the secret API key is plainly visible to anybody with access to your code file. Never load this code file into a repository such as GitHub!

Step 4: Generate Your DALL·E Image

Now that you’re authenticated with OpenAI, you can generate your first DALL·E image. To do this, call the openai.Image.create() function, passing in the model name, prompt, and size of the image you want to create.

import openai # Authenticate with OpenAI API Key

openai.api_key = 'sk-...' # Generate images using DALL-E

response = openai.Image.create( model="image-alpha-001", prompt="a coder learning with Finxter", size="512x512"

) print(response.data[0]['url'])

In the code above, we specified the DALL·E model we wanted to use (image-alpha-001), provided a prompt for the image we wanted to create (a coder learning with Finxter), and specified the size of the image we wanted to create (512x512).

Once you’ve generated your image, you can retrieve the image URL from the API response and display it in your Python code or in a web browser.

print(response.data[0]['url'])

Conclusion

Using OpenAI’s DALL·E to generate images is a powerful tool that can be used in various applications. So exciting!

With just a few lines of Python code, you can create unique images that match specific text descriptions. By following the four easy steps outlined in this article, you can get started generating your own DALL·E images today.
