globals dict error

Question

When I try to run this code

"""Hello World"""

print globals()[__doc__]

Why do I get this error ?

Traceback (most recent call last):
File "D:\myProjects\python\Python-13.py", line 3, in <module>
print globals()[__doc__]
KeyError: 'Hello World'

Context : I just want the doc string of current module

Answer 1

You need print globals()['__doc__'].

Answer 2

The docstring of the current module is __doc__. In your code you are trying to use that string as key in the global dictionary of the module.

To be clear, to print the docstring, just do print __doc__.
