请给我10个python语言下的正则表达式实例代码

好的，以下是10个Python语言下的正则表达式实例代码：

1. 匹配手机号码

import re

phone_number = "13800001111"
pattern = r"^1[3-9]\d{9}$"

if re.match(pattern, phone_number):
    print("是合法的手机号码")
else:
    print("不是合法的手机号码")

2. 匹配邮箱地址

import re

email = "abc@xyz.com"
pattern = r"^[a-zA-Z0-9_-]+@[a-zA-Z0-9_-]+(\.[a-zA-Z0-9_-]+)+$"

if re.match(pattern, email):
    print("是合法的邮箱地址")
else:
    print("不是合法的邮箱地址")

3. 匹配IP地址

import re

ip_address = "192.168.0.1"
pattern = r"^((25[0-5]|2[0-4]\d|[01]?\d?\d)(\.(25[0-5]|2[0-4]\d|[01]?\d?\d)){3})$"

if re.match(pattern, ip_address):
    print("是合法的IP地址")
else:
    print("不是合法的IP地址")

4. 匹配URL地址

import re

url = "https://www.google.com"
pattern = r"^(http|https)://[a-zA-Z0-9]+\.[a-zA-Z0-9]+(\.[a-zA-Z0-9]+)*(:[0-9]+)?(/[a-zA-Z0-9_-]+)*(\?[a-zA-Z0-9_]+=[a-zA-Z0-9_]+(&[a-zA-Z0-9_]+=[a-zA-Z0-9_]+)*)?$"

if re.match(pattern, url):
    print("是合法的URL地址")
else:
    print("不是合法的URL地址")

5. 匹配身份证号码

import re

id_number = "610103199001011234"
pattern = r"^\d{17}(\d|X)$"

if re.match(pattern, id_number):
    print("是合法的身份证号码")
else:
    print("不是合法的身份证号码")

6. 匹配日期格式

import re

date = "2022-01-01"
pattern = r"^\d{4}-\d{2}-\d{2}$"

if re.match(pattern, date):
    print("是合法的日期格式")
else:
    print("不是合法的日期格式")

7. 匹配中文字符

import re

chinese = "你好，世界！"
pattern = r"[\u4e00-\u9fa5]+"

if re.match(pattern, chinese):
    print("是中文字符")
else:
    print("不是中文字符")

8. 匹配邮政编码

import re

postal_code = "100101"
pattern = r"^[0-9]{6}$"

if re.match(pattern, postal_code):
    print("是合法的邮政编码")
else:
    print("不是合法的邮政编码")

9. 匹配QQ号码

import re

qq_number = "123456789"
pattern = r"^[1-9][0-9]{4,}$"

if re.match(pattern, qq_number):
    print("是合法的QQ号码")
else:
    print("不是合法的QQ号码")

10. 匹配包含数字和字母的密码

import re

password = "Abc123456"
pattern = r"^(?=.*[a-zA-Z])(?=.*\d)[a-zA-Z\d]{8,}$"

if re.match(pattern, password):
    print("是合法的密码")
else:
    print("不是合法的密码")
