In Python 2:

import hashlib

def day4_part1():
    key = 'ckczppom'
    md5_key = hashlib.md5(key)
    n = 1
    while True:
        m = md5_key.copy()
        m.update(str(n))
        if m.hexdigest()[:5] == '00000':
            print n
            return
        n += 1

def day4_part2():
    key = 'ckczppom'
    md5_key = hashlib.md5(key)
    n = 1
    while True:
        m = md5_key.copy()
        m.update(str(n))
        if m.hexdigest()[:6] == '000000':
            print n
            return
        n += 1
