Explain How to comment out a block of code in Python 

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.
