根据配置，在达到目标(查找和替换文本)1次、2次或3次时停止脚本

import re

def find_and_replace(target_text, search_text, replace_text, stop_after):
    count = 0
    while count < stop_after:
        if search_text in target_text:
            target_text = re.sub(search_text, replace_text, target_text)
            count += 1
        else:
            break
    return target_text

# 示例用法
target_text = "This is a sample text. This text needs to be replaced. This text needs to be replaced again."
search_text = "text"
replace_text = "word"
stop_after = 2

result = find_and_replace(target_text, search_text, replace_text, stop_after)
print(result)
