I have been reading the argparse section of the 3.3 docs, and running all

But in section 16.4.2.6. for the formatter_class, the second example in
that section illustrating RawDescriptionHelpFormatter, the example code
is:
parser = argparse.ArgumentParser(
prog='PROG',
formatter_class=argparse.RawDescriptionHelpFormatter,
description=textwrap.dedent('''\
Please do not mess up this text!
--------------------------------
I have indented it
exactly the way
I want it
'''))
parser.print_help()
But trying to run this gives a NameError on the "description=" line,
saying textwrap is not
defined. If I delete the "textwrap.dedent" (with or without also deleting
the extra parentheses) it will then run, but without the un-indenting it
is trying to illustrate.
What is the proper way to enable the dedent() method here?
textwrap is a module like argparse, and the example doesn't show
import argparse
either. Insert
import textwrap
at the beginning of your module and the code should run without error.
Thanx.
Guess I shoulda searched for textwrap or dedent in the docs. :-)
