Cracking hashes with Python

[TheRandomPast .]

This is my code

import md5
import sys

def chklength(hashes):
    if len(hashes) != 32:
        print '[-] Improper length for md5 hash.'
        sys.exit(1)
characters=range(48,57)+range(65,90)+range(97,122)
def checkPassword(password):
    #print password
    m = md5.new(password)
    if (m.hexdigest() == hash):
        print "match [" + password + "]"
        sys.exit()

def recurse(width, position, baseString):
    for char in characters:
        if (position < width - 1):
            recurse(width, position + 1, baseString + "%c" % char)
        checkPassword(baseString + "%c" % char)
        print "Target Hash [" + hash+ " string: "+ baseString
def brute_force():
    maxChars = 32
    for baseWidth in range(1, maxChars + 1):
        print "checking passwords width [" + `baseWidth` + "]"
        recurse(baseWidth, 0, "")
def dictionary():
    for line in File.readlines():
        checkPassword(line.strip('\n'))
hash =raw_input("Input MD5 hash:")
option=input("Choose method:1=Brute Force; 0=Dictionary")
if(option==1):
    chklength()
    brute_force()
else:
    if(option==0):
        File=open("dict.txt")
        chklength()
        dictionary()
    else:
        print "You picked wrong!"

IT WORKS! ...(Almost) My chklength isn't working. Can anyone see why not?
I'm stumped.
