Is there a way to get source of a python file while executing within the python file?

Question

Assuming you have a python file like so

#python
#comment
x = raw_input()
exec(x)

How could you get the source of the entire file, including the comments with exec?

Answer 1

This is exactly what the inspect module is there for. See the Retrieving source code section in particular.

If you're trying to get the source of the currently-running module:

thismodule = sys.modules[__name__]
inspect.getsource(thismodule)
