One approach would be to use regular expressions.

import re
....
match = re.search('\.pdf',line)
start = match.regs[0][0]	# position of the '.' within line
while line[start] != ' ':	# assume no spaces in filename!
    start = start - 1		# decrement index

filename = line[start+1:match.regs[0][1]] # extract file name.

A starter maybe?
