在Python中查找字符串中的模式并打印

import re

def find_pattern(string, pattern):
    result = re.findall(pattern, string)
    if result:
        for match in result:
            print(match)
    else:
        print("No match found")

string = "This is a test string. The pattern to search is 'test'"
pattern = r'\btest\b'  # 使用\b表示单词边界，只匹配完整的单词
find_pattern(string, pattern)

test
