[Tutor] invalid syntax? huh!?!

[Ray Leggett]

Ok, I'm writing a script in Python 2.2 on windows that basically scans
another python module and lists all the lines beginning with "class" and
"def" in them.  Basically, it will print out a reference to the module.

Well, i wrote the thing in maybe 20 minutes tops.  Ran it with another
python module as an argument, and got the following:

File "C:\scripts\modscan.py", line 16
  for line in fp.readlines()
  ^
SyntaxError:  invalid syntax

Now, this is really puzzling to me.  As far as I can tell, the for loop I
used is correct in any number of languages, including python.  Here is the
script: (formatting a little mangled by outlook)
--------------------------------------------------------
#!/usr/bin/python

"scans a python module and lists all classes and functions"

import sys
import re

ModuleToScan = sys.argv[1]

def SetRegExp():
 ScanClass = re.compile("class")
 ScanDef = re.compile("def")

def ScanModule(ModuleToScan):
 fp = open(ModuleToScan)
  for line in fp.readlines()
   if ScanClass.search(line):
    print line
   else
    if ScanDef.search(line):
    print line
 fp.close()
 return

SetRegExp()
ScanModule(ModuleToScan)
--------------------------------------------------------------------------

Any ideas?  This one has me really puzzled.
