'Python -m' in terminal : <p>I have met this pattern for quite some time when I see people try to execute a package through python. But I am not sure what does '-m' mean here. Is it a specific pattern that you need to follow?
for example:</p>

<p><code>python -m [library] download [model]</code></p>

<p>or </p>

<pre><code>python -m venv env (to create a virtual environment in Python)
</code></pre>

<p>Anyone could explain to me?</p>
