python中正在跳过最后一个匹配的字符串

import re

def remove_last_occurrence(text, pattern):
    # 找到最后一个匹配的位置
    last_match = re.search(pattern[::-1], text[::-1])
    if last_match:
        # 计算开始和结束位置
        start = len(text) - last_match.end() - len(pattern) + 1
        end = len(text) - last_match.start()
        # 移除最后一个匹配的字符串
        return text[:start] + text[end:]
    return text

# 示例
texts = ["this is a test skipme", "another example skipme here"]
pattern = "skipme"

for text in texts:
    result = remove_last_occurrence(text, pattern)
    print(f"Original: {text}, Modified: {result}")
