Python csv.reader: How do I return to the top of the file?

Question

When I'm moving through a file with a csv.reader, how do I return to the top of the file. If I were doing it with a normal file I could just do something like "file.seek(0)". Is there anything like that for the csv module?

Thanks ahead of time ;)

Answer 1

You can seek the file directly. For example:

>>> f = open("csv.txt")
>>> c = csv.reader(f)
>>> for row in c: print row
['1', '2', '3']
['4', '5', '6']
>>> f.seek(0)
>>> for row in c: print row   # again
['1', '2', '3']
['4', '5', '6']
