Hi! I'm a new user of python, and have problem. I have a plain ascii file: 1aaaaaaaaaaaa1......1 1cccccccccccc2......1 1xxxxxxxxxxxx1......1 I want to create a new file which contains only lines with '1' on 15th position. I've tried this:
import string
f=open('/test/test.asc','r')
o=open('/test/out.asc','w')
for line in f:
s= f.readline()
if s[15]=='1' :
o.write(s)
o.close()
f.close()
Why it doesn't work ('s' contains ' ' )?
