How to comment out a block of code in Python [duplicate]
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.
