File handling (removing comments)

From the file string1.py remove the comment lines. For the sake of simplicity, remove only those lines that start with a # sign (leading whitespaces may occur before the # sign). Write the result to a file called string1_clean.py.

Example:

def mix_up(a, b):
    # +++your code here+++
    return
...
# Provided main() calls the above functions with interesting inputs,
# using test() to check if each result is correct or not.
def main():
    print 'donuts'
    # Each line calls donuts, compares its result to the expected for that call.
    test(donuts(4), 'Number of donuts: 4')

In this example there are 4 lines that need to be removed.
