利用python库random，string生成大小写字母和数字的随机验证码
import random
import string
def generate_code(bit_num):
'''
:param bit_num: 生成验证码位数
:return: 返回生成的验证码
'''
all_str = string.printable.split('!')[0]
code = ''.join([random.choice(all_str) for i in range(bit_num)])
return code
if __name__ == '__main__':
code = generate_code(6)
print(code)
生成带特殊符号的验证码如下
import random
import string
def generate_code(bit_num):
'''
:param bit_num: 生成验证码位数
:return: 返回生成的验证码
'''
all_str = string.printable
code = ''.join([random.choice(all_str) for i in range(bit_num)])
return code
if __name__ == '__main__':
code = generate_code(6)
print(code)
