you're opening the file for write only. use 'w+' for read-write
access. don't forget to use c.seek() to reposition the file pointer
if you want to read what you've just written.

here you get a file like object from which you can retreive the data.
e.g "print f.read()"

this creates a file named "tester" your file opened and bound to c
would be in confilct with that file if it were in the same directory
so you don't need c.

either you use f or k but you don't need both.

because urlretrieve created its own file in the current directory.
