Problem with doctest

[ast]

Hello

doctest of the sample function funct() doesn't works
because flag used by funct() is the one defined in
first line "flag = True" and not the one in the
doctest code ">>> flag = False".

Any work around known ?


flag = True              # <- funct() always use this one

def funct():
     """
     Code for doctest:

     >>> flag = True
     >>> funct()
     'Yes'
     >>> flag = False     #  <- Ignored unfortunalely
     >>> funct()
     'No'
     """

     if flag:
         return "Yes"
     else:
         return "No"

if __name__ == "__main__":
     import doctest
     doctest.testmod()



Failed example:
     funct()
Expected:
     'No'
Got:
     'Yes'
