正则表达式实现

正则表达式强大、便捷、高效,但掌握起来有一定难度

import re
phone = input("请输入11位手机号码：")
pattern = re.compile(r'^(13[0-9]|14[0|5|6|7|9]|15[0|1|2|3|5|6|7|8|9]|'
                         r'16[2|5|6|7]|17[0|1|2|3|5|6|7|8]|18[0-9]|'
                         r'19[1|3|5|6|7|8|9])\d{8}$')
if pattern.search(phone):
    print("手机号码合法！")
else:
