Passing command line argument to another file imported in Python

Question

I have a python file (html2text.py) which gives the desired result when i pass command line argument to it i.e., in the following way:

python html2text.py file.txt

where file.txt contains the source code of a web-site and the result is displayed on the console...

I want to use it in another file (let say a.py) and store the result (which was getting printed on the console) in a string.

For this I need to first import the file (html2text.py) in my file (a.py). Can anyone tell me how do I proceed further...?

Good way is to create some API in your html2text.py. For example:

# html2text.py def parse(filename): f = open(filename) # do the stuff return output_string def main(): import sys print parse(sys.argv[1]) if __name__ == '__main__': main()

Then you will be able to use it in your a.py:

import html2text # main() will not run import sys output = html2text.parse(sys.argv[1])

I think the best way is the reorganize a little your html2text.py file. Append the line like this to your file:

def main(): message = sys.stdin.readlines() a = your_def(message) if __name__ == '__main__': main()

Now you're sure, that when invoking the file from command line, everything will go fine. Moreover, if you have everything kept in functions and classes, you can now in your a.py

import html2text

and work on it already in a.py.
