Question

Answer 1

You'll want to open the file in append-mode ('a'), rathen than write-mode ('w'); the Python documentation explains the different modes available.

Also, you might want to consider using the with keyword:

It is good practice to use the with keyword when dealing with file objects. This has the advantage that the file is properly closed after its suite finishes, even if an exception is raised on the way.

>>> with open('/tmp/workfile', 'a') as f:
...     f.write(your_input)
