Python实现随机生成手机号及正则验证手机号的方法

# -*- coding: utf-8 -*-
import random
def create_phone():
  # 第二位数字
  second = [3, 4, 5, 7, 8][random.randint(0, 4)]
  # 第三位数字
  third = {
    3: random.randint(0, 9),
    4: [5, 7, 9][random.randint(0, 2)],
    5: [i for i in range(10) if i != 4][random.randint(0, 8)],
    7: [i for i in range(10) if i not in [4, 9]][random.randint(0, 7)],
    8: random.randint(0, 9),
  }[second]
  # 最后八位数字
  suffix = random.randint(9999999,100000000)
  # 拼接手机号
  return "1{}{}{}".format(second, third, suffix)
# 生成手机号
phone = create_phone()
print(phone)

# -*- coding: utf-8 -*-
import random
