Copy and Reverse

[wocosc]

So far, I have:

from string import *
def reverse():
fname = raw_input("Enter a Filename: ")
infile = open(fname, 'r')
data = infile.read()
list(data)
print fname[-1:1]


I need python to read the file (whichever the user wants to open), but print it in reverse and save it. I know I need to treat the file as a string, but I am obviously not doing something right.. Any help would be great.

Here's one way of doing it:

lineList = open('your_file').readlines()
outStr = ''
for line in lineList:
    s = list(line.strip())        # strip newline character and make list of characters
    s.reverse()                    # reverse character list in place
    outStr += '%s\n' % (''.join(s))        # create output string for writing
