You may consider using triple-quote """ strings to create something akin to multi-line comments in Python, but this isn’t a perfect technique and your “comments” may turn into accidental docstrings. This is the only way to get “true” source code comments that are removed by the Python parser. The recommended way to comment out multiple lines of code in Python is to use consecutive # single-line comments. Unlike other programming languages Python doesn’t support multi-line comment blocks out of the box. Multi-line Comments in Python – Key Takeaways Personally I’ll try to avoid them in production-ready code, but I occasionally use them when I’m working on a source file to jot down notes or to make little ad-hoc to-do lists. Unless used as docstrings, they generate no code! :-)” ( Source)īut there you have it-in some cases using triple-quoted strings to make a comment block might be the right choice. “Python tip: You can use multi-line strings as multi-line comments. I’ll admit I was slightly surprised to find this “fake” block commenting style was endorsed by Guido van Rossum, the creator of Python: Like I said earlier, the only way to get “true” multi-line comments in Python that get ignored by the parser is to use multiple # single-line comments. It can even be accessed programmatically at runtime. They’re different from source code comments:Ī comment is removed by the parser, whereas a docstring ends up in the bytecode and is associated with the documented object.

This even works in reverse, that is, I can select a block of single-line comments and when I hit the cmd + / keyboard shortcut the whole block gets uncommented again. In my Sublime Text development setup I simply select a couple of lines using shift and the cursor keys (or the mouse) and then I hit cmd + / to comment them out all at once. Most code editors have a shortcut for block commenting. If it bothers you that Python doesn’t support proper multiline comments because you think it takes more effort to comment out multiple lines of code, here’s a handy tip for you: This is also the only way to write “real” comment blocks in Python that are ignored by the parser. So this is what I’d recommend that you use most of the time. In my experience, most Python projects follow this style and Python’s PEP 8 style guide also favors repeated single-line comments. # This is a "block comment" in Python, made # out of several single-line comments.
