Better replacement for Comma (,) in filename : <p>I am looking for a more convenient way to name my python scripts.
At the moment they look similar to this:</p>

<p><code>a1_testing_A,B,C.py</code></p>

<p><code>a2_testing_A,B_and_C,X.py</code></p>

<p>I want to rename them, such that the names look prettier while the replacement should cause no trouble with the interpreter (e.g. "blank space" or "/" is inconvenient).
Is there a convention how to do that?
I would be grateful for suggestions.</p>
