9.9 Python Document String

9.9 Python Document String. Enter the directory where the Python standard library resides. Check each. py file to see if there is a __doc__ string, and if so, make a proper collation of its format. After your program has finished executing, you should generate a nice list. It lists which modules have the document string, and the contents of the document string. The list is appended with the name of the module without the document string.
