python生成任意位数的验证码（只有数字+大小写字母）

# 方法一 import random import string totle_string = string.ascii_letters + string.digits def auth_code(num): res = ''.join(random.sample(totle_string, num)) return res # 方法二 import random import string totle_string = string.ascii_letters + string.digits def auth_code(num): l = [i for i in totle_string] random.shuffle(l) return ''.join(l[0:num])
