This question already has an answer here:
- Why doesn't Python have multiline comments? 16 answers
Is there a mechanism to comment out large blocks of Python code?
Right now, the only ways I can see of commenting out code are to either start every line with a #, or to enclose the code in triple quotes: """.
The problem with these is that inserting # before every line is cumbersome and """ makes the string I want to use as a comment show up in generated documentation.
After reading all comments, the answer seems to be "No".
Python does not have such a mechanism. Prepend a
#to each line to block comment. For more information see PEP 8. Most Python IDEs support a mechanism to do the block-commenting-with-pound-signs automatically for you. For example, in IDLE on my machine, it's Alt+3 and Alt+4.Don't use triple-quotes; as you discovered, this is for documentation strings not block comments, although it has a similar effect. If you're just commenting things out temporarily, this is fine as a temporary measure.
In Eclipse + PyDev, Python block commenting is similar to Eclipse Java block commenting; select the lines you want to comment and use Ctrl + / to comment. To uncomment a commented block, do the same thing.
At least in VIM you can select the first column of text you want to insert using Block Visual mode (
CTRL+Vin non-windows VIMs) and then prepend a#before each line using this sequence:In Block Visual mode
Imoves to insert mode with the cursor before the block on its first line. The inserted text is copied before each line in the block.The only cure I know for this is a good editor. Sorry.
The only mechanism to comment out Python code (understood as code ignored by the interpreter) is the #.
As you say, you can also use string literals, that are not ignored by the interpreter, but can be completely irrelevant for the program execution.
In Visual Studio using the Python Tools for Visual Studio, blocks can be commented out by Ctrl+K, Ctrl+C and uncommented by Ctrl+K, Ctrl+U.
