You can use <code>compileall</code> in the terminal. The following command will go recursively into sub directories and make pyc files for all the python files it finds. The <a href="https://docs.python.org/2/library/compileall.html" rel="noreferrer">compileall</a> module is part of the python standard library, so you don't need to install anything extra to use it.

I found several ways to compile python scripts into bytecode

<ol>
<li>Using <code>py_compile</code> in terminal:

<pre><code>python -m py_compile File1.py File2.py File3.py ...
</code></pre>

<code>-m</code> specifies the module(s) name to be compiled. 

Or, for interactive compilation of files

<pre><code>python -m py_compile -
File1.py
File2.py
File3.py
 .
 .
 .
</code></pre></li>
<li>Using <code>py_compile.compile</code>:

<pre><code>import py_compile
py_compile.compile('YourFileName.py')
</code></pre></li>
<li>Using <code>py_compile.main()</code>:

It compiles several files at a time.

<pre><code>import py_compile
py_compile.main(['File1.py','File2.py','File3.py'])
</code></pre>

The list can grow as long as you wish. Alternatively, you can obviously pass a list of files in main or even file names in command line args.

Or, if you pass <code>['-']</code> in main then it can compile files interactively.</li>
<li>Using <code>compileall.compile_dir()</code>:

<pre><code>import compileall
compileall.compile_dir(direname)
</code></pre>

It compiles every single Python file present in the supplied directory.</li>
<li>Using <code>compileall.compile_file()</code>:

<pre><code>import compileall
compileall.compile_file('YourFileName.py')
</code></pre></li>
</ol>

<blockquote>
You can enforce the same layout of <code>.pyc</code> files in the folders as in
Python2 by using:
<code>python3 -m compileall -b &lt;pythonic-project-name&gt;</code>
The option <code>-b</code> triggers the output of <code>.pyc</code> files to their
