随机n 位验证码

第一种纯数字六位验证码

import random
def get_code(n=6):
    s = ''
    for i in range(n):
        num = random.randint(0,9)
        s+=str(num)
    return s
ret=get_code()
print(ret)


#第二种方法 随机验证码 包括数字 字母等
# import random
#
# lst = []
# for i in range(48,59):
#     lst.append(chr(i))
#
# for i in range(ord("a"), ord("z") + 1):
#     lst.append(chr(i))
#
# for i in range(ord('A'), ord('Z') + 1):
#     lst.append(chr(i))
#
# print(random.sample(lst,6))

第三种 所有格式全部通用

# import random
# def code(n=4):
#     end = ''
#     for i in range(n):
#         num = str(random.randint(0,9))
#         alpha_up = chr(random.randint(65,90))
#         alpha_low = chr(random.randint(97,122))
#         aim = random.choice([num,alpha_up,alpha_low])
#         end += aim
#     return end
# print(code())
#

# import random
# def code(n=4,alpha = True):
#     end = ''
#     for i in range(n):
#         aim = str(random.randint(0,9))
#         if alpha:
#             alpha_up = chr(random.randint(65,90))
#             alpha_low = chr(random.randint(97,122))
#             aim = random.choice([aim,alpha_up,alpha_low])
#         end += aim
#     return end
# print(code(n=6,alpha=False))
# print(code())
