<h2 class="wp-embed-aspect-4-3 wp-has-aspect-ratio">Problem Formulation and Solution Overview</h2>
<p class="wp-embed-aspect-4-3 wp-has-aspect-ratio">In this article, you’ll learn how to configure and display a progress bar.</p>
<p>A progress bar is commonly used in Python or, for that matter, any other programming language to show the user an application’s progress. For example, an installation, a transferring of files, or any other commands. </p>
<p>The <a rel="noreferrer noopener" href="https://academy.finxter.com/" data-type="URL" data-id="https://academy.finxter.com/" target="_blank">Finxter Academy</a> recommends implementing this to visually display to the user what is happening behind the scenes. </p>
<hr class="wp-block-separator has-alpha-channel-opacity" />
<p class="wp-embed-aspect-16-9 wp-has-aspect-ratio has-global-color-8-background-color has-background"><em><img src="https://s.w.org/images/core/emoji/14.0.0/72x72/1f4ac.png" alt="?" class="wp-smiley" style="height: 1em; max-height: 1em;" /> <strong>Question</strong>: How would we write code to display a progress bar?</em></p>
<p class="wp-embed-aspect-16-9 wp-has-aspect-ratio">We can accomplish this task by one of the following options:</p>
<ul type="video" class="wp-embed-aspect-16-9 wp-has-aspect-ratio">
<li><strong>Method 1</strong>: Use a <a rel="noreferrer noopener" href="https://blog.finxter.com/python-loops/" data-type="URL" data-id="https://blog.finxter.com/python-loops/" target="_blank"><code>for</code></a> loop</li>
<li><strong>Method 2</strong>: Use <code><a rel="noreferrer noopener" href="https://pypi.org/project/apytl/" data-type="URL" data-id="https://pypi.org/project/apytl/" target="_blank"></a><a rel="noreferrer noopener" href="https://pypi.org/project/apytl/" data-type="URL" data-id="https://pypi.org/project/apytl/" target="_blank">apytl</a> </code>library <a rel="noreferrer noopener" href="https://pypi.org/project/apytl/" data-type="URL" data-id="https://pypi.org/project/apytl/" target="_blank"><code>Bar().drawbar()</code></a> function</li>
<li><strong>Method 3</strong>: Use <a rel="noreferrer noopener" href="https://pypi.org/project/alive-progress/1.0/" data-type="URL" data-id="https://pypi.org/project/alive-progress/1.0/" target="_blank"><code>alive-progress</code></a></li>
<li><strong>Method 4</strong>: Use <a rel="noreferrer noopener" href="https://pypi.org/project/tqdm/" data-type="URL" data-id="https://pypi.org/project/tqdm/" target="_blank"><code>tqdm</code></a></li>
<li><strong>Method 5</strong>: Use <a href="https://pypi.org/project/progress/" data-type="URL" data-id="https://pypi.org/project/progress/" target="_blank" rel="noreferrer noopener"><code>progress</code></a></li>
</ul>

<p>Next, a <a rel="noreferrer noopener" href="https://blog.finxter.com/python-loops/" data-type="URL" data-id="https://blog.finxter.com/python-loops/" target="_blank"><code>for</code></a> loop is instantiated. This loop uses the <a href="https://blog.finxter.com/python-range-function/" data-type="URL" data-id="https://blog.finxter.com/python-range-function/"><code>range</code></a> function to set the start position (0 by default) and the stop position (21-1). Inside this loop, the following occurs:</p>
<ul>
<li>The first line uses a carriage return (<code>\r</code>) to start the code on a new line.</li>
<li>The following line determines how the progress bar appears by:
<ul>
<li>Left-aligning the emoji(s) inside the square brackets <code>[%-20s]</code>.</li>
<li>Configuring the progress percentage <code>%d%%" %</code> (example <code>15%</code>).</li>
<li>Determining the visual emoji progress <code>('😁'*x, 5*x)</code>.</li>
</ul>
</li>
<li>Then <code>sys.stdout.flush()</code> writes everything in the buffer to the terminal.</li>
<li>The code pauses for the stated period (<code>0.75</code>).</li>
</ul>
<p>The loop continues until 100% has been attained. Below is the end result.</p>

<p>To run this code error-free, install the required library. Click <a rel="noreferrer noopener" href="https://pypi.org/project/apytl/" data-type="URL" data-id="https://pypi.org/project/apytl/" target="_blank">here</a> for installation instructions.</p>

<p>Next, the total number of iterations to carry out is declared as <code>10</code> and saved to <code>total_iterations</code>.</p>
<p>To understand what is going on in the <a rel="noreferrer noopener" href="https://blog.finxter.com/python-loops/" data-type="URL" data-id="https://blog.finxter.com/python-loops/" target="_blank"><code>for</code></a> loop, let’s write some test code to see what the values of <code>index</code>, <code>value</code> and <code>total_iterations</code> are doing:</p>

<p>As you can see from the output, the <code>index</code> and <code>value </code>variables count from 0 (<a href="https://blog.finxter.com/python-range-function/" data-type="URL" data-id="https://blog.finxter.com/python-range-function/"><code>range</code></a> default start position) to the stop position of 9 (10-1).

<h2 class="wp-embed-aspect-4-3 wp-has-aspect-ratio">Problem Formulation and Solution Overview</h2>
<p class="wp-embed-aspect-4-3 wp-has-aspect-ratio">In this article, you’ll learn how to configure and display a progress bar.</p>
<p>A progress bar is commonly used in Python or, for that matter, any other programming language to show the user an application’s progress. For example, an installation, a transferring of files, or any other commands. </p>
<p>The <a rel="noreferrer noopener" href="https://academy.finxter.com/" data-type="URL" data-id="https://academy.finxter.com/" target="_blank">Finxter Academy</a> recommends implementing this to visually display to the user what is happening behind the scenes. </p>

<p class="wp-embed-aspect-16-9 wp-has-aspect-ratio">We can accomplish this task by one of the following options:</p>
<ul type="video" class="wp-embed-aspect-16-9 wp-has-aspect-ratio">
<li><strong>Method 1</strong>: Use a <a rel="noreferrer noopener" href="https://blog.finxter.com/python-loops/" data-type="URL" data-id="https://blog.finxter.com/python-loops/" target="_blank"><code>for</code></a> loop</li>
<li><strong>Method 2</strong>: Use <code><a rel="noreferrer noopener" href="https://pypi.org/project/apytl/" data-type="URL" data-id="https://pypi.org/project/apytl/" target="_blank"></a><a rel="noreferrer noopener" href="https://pypi.org/project/apytl/" data-type="URL" data-id="https://pypi.org/project/apytl/" target="_blank">apytl</a> </code>library <a rel="noreferrer noopener" href="https://pypi.org/project/apytl/" data-type="URL" data-id="https://pypi.org/project/apytl/" target="_blank"><code>Bar().drawbar()</code></a> function</li>
<li><strong>Method 3</strong>: Use <a rel="noreferrer noopener" href="https://pypi.org/project/alive-progress/1.0/" data-type="URL" data-id="https://pypi.org/project/alive-progress/1.0/" target="_blank"><code>alive-progress</code></a></li>

Inside this loop, the following occurs:</p>
<ul>
<li>The first line uses a carriage return (<code>\r</code>) to start the code on a new line.</li>
<li>The following line determines how the progress bar appears by:
<ul>
<li>Left-aligning the emoji(s) inside the square brackets <code>[%-20s]</code>.</li>
<li>Configuring the progress percentage <code>%d%%" %</code> (example <code>15%</code>).</li>
<li>Determining the visual emoji progress <code>('😁'*x, 5*x)</code>.</li>
</ul>
</li>
<li>Then <code>sys.stdout.flush()</code> writes everything in the buffer to the terminal.</li>
<li>The code pauses for the stated period (<code>0.75</code>).</li>
</ul>
<p>The loop continues until 100% has been attained. Below is the end result.</p>

<h2>Method 2: Use apytl Library</h2>
<p class="has-global-color-8-background-color has-background">This method imports the <a rel="noreferrer noopener" href="https://blog.finxter.com/category/python-time/" data-type="URL" data-id="https://blog.finxter.com/category/python-time/" target="_blank"><code>time</code></a> and <a rel="noreferrer noopener" href="https://pypi.org/project/apytl/" data-type="URL" data-id="https://pypi.org/project/apytl/" target="_blank"><code>apytl</code></a> libraries to generate a custom progress bar. </p>
<p>To run this code error-free, install the required library. Click <a rel="noreferrer noopener" href="https://pypi.org/project/apytl/" data-type="URL" data-id="https://pypi.org/project/apytl/" target="_blank">here</a> for installation instructions.</p>
<pre class="EnlighterJSRAW" data-enlighter-language="python" data-enlighter-theme="" data-enlighter-highlight="7" data-enlighter-linenumbers="" data-enlighter-lineoffset="" data-enlighter-title="" data-enlighter-group="">import time
import apytl total_iterations = 10 for index, value in enumerate(range(total_iterations)): apytl.Bar().drawbar(value, total_iterations, fill='*') time.sleep(0.75)</pre>
<p>Above imports the <a rel="noreferrer noopener" href="https://blog.finxter.com/category/python-time/" data-type="URL" data-id="https://blog.finxter.com/category/python-time/" target="_blank"><code>time</code></a> library to call the sleep command and the <code><a rel="noreferrer noopener" href="https://blog.finxter.com/category/python-sys/" data-type="URL" data-id="https://blog.finxter.com/category/python-sys/" target="_blank"></a><a rel="noreferrer noopener" href="https://pypi.org/project/apytl/" target="_blank">apytl</a></code> library to display the progress bar.</p>
<p>Next, the total number of iterations to carry out is declared as <code>10</code> and saved to <code>total_iterations</code>.</p>
<p>To understand what is going on in the <a rel="noreferrer noopener" href="https://blog.finxter.com/python-loops/" data-type="URL" data-id="https://blog.finxter.com/python-loops/" target="_blank"><code>for</code></a> loop, let’s write some test code to see what the values of <code>index</code>, <code>value</code> and <code>total_iterations</code> are doing:</p>
<pre class="EnlighterJSRAW" data-enlighter-language="python" data-enlighter-theme="" data-enlighter-highlight="4" data-enlighter-linenumbers="" data-enlighter-lineoffset="" data-enlighter-title="" data-enlighter-group="">total_iterations = 10 for index, value in enumerate(range(total_iterations)): print(index, value, total_iterations)</pre>
<p>As you can see from the output, the <code>index</code> and <code>value </code>variables count from 0 (<a href="https://blog.finxter.com/python-range-function/" data-type="URL" data-id="https://blog.finxter.com/python-range-function/"><code>range</code></a> default start position) to the stop position of 9 (10-1). Notice the value of <code>total_iterations</code> does not change.</p>

</tr>
</tbody>
</table>
</figure>
<p>Referring back to the code directly below the Method 2 heading, the next line is: <code>apytl.Bar().drawbar(value, total_iterations, fill='*')</code>.</p>
<p>This function is passed three (3) arguments:</p>
<ul>
<li>The variable <code>value</code>, which you can see from the above, increments by one (1) each iteration.</li>
<li>The variable <code>total_iterations</code>, which remains constant at <code>10</code>.</li>
<li>The fill value. This example uses the asterisk (<code>*</code>) character. However, feel free to use an emoji or other symbol.</li>

<ul>
<li>The <code>alive_bar </code>is called and passed the argument <code>x</code> and the bar type. For this example, <code>solid </code>was selected.
