在Python中有效匹配多个正则表达式

import re

# 定义正则表达式列表
regex_list = [
    r'\d+',  # 匹配数字
    r'\w+',  # 匹配字母和数字
    r'\s+'   # 匹配空格
]

# 要匹配的字符串
text = "Hello, I have 3 cats and 5 dogs. There are 2 birds in the cage."

# 遍历正则表达式列表，并在文本中查找匹配项
for regex in regex_list:
    matches = re.findall(regex, text)
    print(f"Matches for {regex}: {matches}")

Matches for \d+: ['3', '5', '2']
Matches for \w+: ['Hello', 'I', 'have', 'cats', 'and', 'dogs', 'There', 'are', 'birds', 'in', 'the', 'cage']
Matches for \s+: [' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ']
