Python 生成 md5字符串

import hashlib
import random
import string

def getUploadFileNameMD5():
    char_lists = string.ascii_lowercase + string.digits
    randomString = ''.join(random.choice(char_lists) for _ in range(10))
    rsMD5 = hashlib.md5(randomString.encode('utf-8')).hexdigest()
    final = rsMD5[0:8] + '-' + rsMD5[9:13] + '-' + rsMD5[13:17] + '-' + rsMD5[17:21] + '-' + rsMD5[21:33]
    print(final)
    return final
