How to merge few python scripts into one? - python-2.7

Question

I am newbie when it comes to programming and python.
Therefore I've got a question. With my fellow students we have created few python scripts but now we are stuck and have no more ideas. We need to merge few python scripts into one working scripts. Could anyone help us with that, please?

''' Try to retrieve a webpage via its url, and return its contents'''
print '[*] wget()'
#open file like url object from web, based on url
url_file = urllib.urlopen(url)
# get webpage contents
page = url_file.read()
return page

Answer 1

Analyse your scripts and find the common code
Convert the common code into a module
Rewrite the individual programs with the common code
If you then wish to make the individual programs into one big program it will be much easier
