Manually keying in a number for list indices in python

Manually keying in a number for list indices in python

I have a list of file name eg. filenames=['blacklisted.txt', 'abc.txt',
'asfafa.txt', 'heythere.txt']
I would like to allow the users to manually choose which file name to
display , for example ,
*
print "Please key in the first log file you would like to use: "
choice1=raw_input()
print"Please key in the second log file you would like to use: "
choice2=raw_input()
filename1=filenames[choice1]
filename2=filenames[choice2]
print filename1
print filename2
*
However, i got the error : filename1=filenames[choice1] TypeError: list
indices must be integers, not str.
Any advice ? Thanks!
