Python：文档字符串未更新

Question

I have a docstring on the very first line of a Python file called a_file.py:

"""some text"""

When I print this using

import a_file
print a_file.__doc__

it prints some text as exptected. However, whenever I change the docstring to

"""different text"""

it still prints some text . I have made sure the file was saved with the changes. I have a feeling that there is something very simple that I am just overlooking. Any help would be greatly appreciated. I have read over the python page on docstrings but still no luck.

EDIT: SOLVED - I have figured it out. Basically, I have a makefile which creates a new file. I was printing from the new file when I thought I was actually printing from the source file. When I re-ran the makefile with the edited text, all was well.

Are you editing the module's doctstring ? If so, you'll need to reimport the file as its docstring is now in the memory. Use reload for this If not, this code works:

>>> def a():
...     """ hello """
...     print 'aa'
... 
>>> a.__doc__
' hello '
>>> a.__doc__ = 'bla bla'
>>> a.__doc__
'bla bla'
