Create a random string in Python

#Hexadecimal(0-9, a-f)
def gen_rand_str_hex(length):
    import os
    import hashlib
	buf = ''
	while len(buf) < length:
		buf += hashlib.md5(os.urandom(100)).hexdigest()
	return buf[0:length]


#Uppercase and lowercase letters+Numbers(0-9, a-z, A-F)
def gen_rand_str(length, chars=None):
    import random
    import string
	if chars is None:
		chars = string.digits + string.letters
	return ''.join([random.choice(chars) for i in range(length)])
