How do I export the output of Python's built-in help() function

Question

I\'ve got a python package which outputs considerable help text from: help(package)

I would like to export this help text to a file, in the format in w

Answer 1

An old question but the newer recommended generic solution (for Python 3.4+) for writing the output of functions that print() to terminal is using contextlib.redirect_stdout:

import contextlib

def write_help(func, out_file):
    with open(out_file, 'w') as f:
        with contextlib.redirect_stdout(f):
            help(func)

Usage example:

write_help(int, 'test.txt')
