Comments for Python

At any time, we can add comments to the program. Annotations are used to illustrate the code, to yourself or others, and when the program runs, the Python interpreter ignores comments directly, so there is no comment that doesn't affect the execution of the program, but it affects whether someone can read your code.

Python comments begin with the  #  text followed by a comment until the end of the line

# This line is all comments ... print ' Hello ' # This is also a comment

Note there is also a clever use, that is, some code we do not want to run, but do not want to delete, you can temporarily block out the comment:

# temporarily don't want to run the following line of code: # print ' Hello, Python. '
