If you’re like me, you try things first in your code and fix the bugs as they come. One frequent bug in Python is the IndentationError: unexpected indent. So, what does this error message mean?

The error IndentationError: unexpected indent arises if you use inconsistent indentation of tabs or whitespaces for indented code blocks such as the if block and the for loop. For example, Python will throw an indentation error, if you use a for loop with three whitespace characters indentation for the first line, and one tab character indentation of the second line of the loop body. To fix the error, use the same number of empty whitespaces for all indented code blocks.

Let’s have a look at an example where this error arises:

for i in range(10): print(i) print('--')

The first line in the loop body uses two whitespaces as indentation level. The second line in the loop body uses three whitespace characters as indentation level. Thus, the indentation blocks are different for different lines of the same block. However, Python expects that all indented lines have structurally the same indentation.

How to Fix Python’s Indentation Error?

To fix the error, simply use the same number of whitespaces for each line of code:

for i in range(10): print(i) print('--')

The general recommendation is to use four single whitespace characters ' ' for each indentation level. If you have nested indentation levels, this means that the second indentation level has 4+4=8 single whitespace characters:

for i in range(10): for j in range(10): print(i, j)

Mixing Tabs and Whitespace Characters Often Causes The Error

A common problem is also that the indentation seems to be consistent—while it really isn’t. The following code has one tab character in the first line and four empty whitespaces in the second line of the indented code block. They look the same but Python still throws the indentation error.

On first sight the indentation looks the same. However, if you go over the whitespaces before print(i), you see that it consists only of a single tabular character while the whitespaces before the print(j) statement consists of a number of empty spaces ' '.

Try It Yourself: Before I tell you what to do about it, try to fix the code yourself in our interactive Python shell:

How to Fix The Indentation Error for All Times?

The source of the error is often the misuse of tabs and whitespace characters. In many code editors, you can set the tab character to a fixed number of whitespace characters. This way, you essentially never use the tabular character itself. For example, if you have the sublime text editor, the following quick tutorial will ensure that you never run in this error ever again:

• Set Sublime Text to use tabs for indentation: View –> Indentation –> Convert Indentation to Tabs
• Uncheck option Indent Using Spaces in the same sub-menu above.

Yesterday PCUI, an open source UI framework for creating game tools and other web applications, was open sourced. PCUI is named as such because it is the UI layer powering the battle tested PlayCanvas game engine. It provides over a dozen controls, as well as implementing logic such as the Observer pattern for making binding your UI to your data. PCUI is open source under the liberal MIT license with the source code available on GitHub.

Details from the PlayCanvas blog:

Today, PlayCanvas is launching PCUI: a new, open source front-end framework for the web.

PCUI is designed with tools developers in mind. It is particularly well suited to building viewer and editor applications, providing a rich set of beautiful and consistent controls. It already powers the PlayCanvas Editor – the world’s most powerful WebGL production tool.

Here you can see tree controls, panels, buttons, checkboxes, toolbars, menus and more. The Editor also relies on PCUI’s observer system, that makes it easy to synchronize the state of your application’s UI with that of the underlying data. Plus, it has a built-in support for history to make implementing redo/undo a breeze.

In addition to the PlayCanvas game engine, PCUI is used to power the PlayCanvas GLTF viewer project as well, a project which is open source and shows you a real-world example of using PCUI in a TypeScript application. PCUI is also extremely well documented with several examples available. If you are interested in learning more about PlayCanvas be sure to check out two part tutorial. You can learn more about the PCUI release in the video below.

The official Nintendo of America Twitter account has just revealed Splatoween 2020! A Splatfest tournament will take place in Splatoon 2 and pit Team Trick against Team Treat in an epic battle. Some super spooky outfits are also shown off in the Tweet letting players into the Halloween spirit before the event starts. More information on the costumes will be available via a news article on your Nintendo Switch later this month.

Team Treat won the original Splatoween Splatfest back in 2018 by a tiny margin, so loyal members of Team Trick are hoping to take their revenge this year. Nintendo also announced a Super Mario-themed Splatfest is happening in January, so Splatoween is a welcome challenge in the interim.

Whether you are new to Splatoween or a returning player, there will be plenty to enjoy. The event begins on October 30, 15:00 PT / 23:00 BST and ends November 1, 14:00 PT / 22:00 BST. Make sure you keep up with everything Nintendo by checking out our Nintendo Direct Mini updates!

Check out the reveal tweet below!

Bubble, bubble, toil and trouble, the #Splatoon2 #Splatoween event approaches! As befitting the spooky season, this #Splatfest will pit #TeamTrick vs. #TeamTreat!

Over the past few months, we have learned so much about productivity, flexibility, resilience and compassion. We have been working in ways we never thought possible, including managing necessary safety precautions, learning to connect with small or large teams while presenting to a screen, taking care of family and friends while being in the next room on calls, adjusting hours to address new demands and so much more. And I am deeply empathetic that this is on top of navigating the emotional toll of all that we are witnessing and experiencing.

At the same time, the pandemic has raised questions about what our employees can expect in the future, so we provided some guidance this week to employees on our thinking about work flexibility. Moving forward, it is our goal to offer as much flexibility as possible to support individual workstyles, while balancing business needs and ensuring we live our culture.

Flexibility can mean different things to each of us, and we recognize there is no one-size-fits-all solution given the variety of roles, work requirements and business needs we have at Microsoft. To address this, we have provided guidance to employees to make informed decisions around scenarios that could include changes to their work site, work location, and/or work hours once offices are open without any COVID-19 restrictions. Our step-by-step guidance includes considerations like office space, salary and benefits, local law, personal taxes, expenses and more.

Our guidance includes:

• Work site (the physical space where you work, e.g. office, center, home, mobile): We recognize that some employees are required to be onsite and some roles and businesses are better suited for working away from the worksite than others. However, for most roles, we view working from home part of the time (less than 50%) as now standard – assuming manager and team alignment.
• Work hours (the hours and days when employees work, e.g. workday start and end times, full- or part-time): Work schedule flexibility is now considered standard for most roles. While part-time continues to be subject to manager approval, our guidance is meant to facilitate an open conversation between a manager and employee regarding considerations.
• Work location (the geographic location where you work, e.g. city and country): Similarly the guidance is there for managers and employees to discuss and address considerations such as role requirements, personal tax, salary, expenses, etc.

Our guidance is to help employees plan ahead for the future. For now, returning to many of our offices around the world is still optional for employees, except for essential onsite roles. While we’ve shared that we will challenge long-held assumptions and seek to be on the forefront of what is possible leveraging technology, we have also communicated that we are not committing to having every employee work from anywhere, as we believe there is value in employees being together in the workplace.

We will continue to evolve our approach to flexibility over time as we learn more.
