获取含有数字和大小字母的随机验证码（python）_python获取数字字母验证码

引入两个模块random string

import random       
import string
def rand_code(a=0, b=0, c=0):
    str1_num = string.digits                        # 0~9
    str2_english = string.ascii_lowercase           # a~z
    str3_English = string.ascii_uppercase           # A~Z
    rand_code = []
    rand_code = random.sample(str1_num,a)  +random.sample(str2_english,b)+random.sample(str3_English,c)        # 获取随机值
    random.shuffle(rand_code)                       # 洗牌
    return ''.join(rand_code)                       # 返回拼接后的字符串
print(rand_code(2,2,2))                             # 调用函数并打印

a  b  c  分别代表需要的数字、小写字母、大写字母的个数。默认入参为0
