使用存储在哈希中的正则表达式提取字符串

import re

hash_data = "name=John&age=30&city=NewYork"

# 使用正则表达式提取字符串
name = re.search(r'name=(\w+)', hash_data).group(1)
age = re.search(r'age=(\d+)', hash_data).group(1)
city = re.search(r'city=(\w+)', hash_data).group(1)

print("Name:", name)
print("Age:", age)
print("City:", city)

Name: John
Age: 30
City: NewYork
