如何从Python文件中提取两个子字符串之间的文本

import re

def extract_text_between_strings(file_path, start_string, end_string):
    with open(file_path, 'r') as file:
        content = file.read()
        pattern = re.escape(start_string) + r'(.*?)' + re.escape(end_string)
        match = re.search(pattern, content, re.DOTALL)
        if match:
            extracted_text = match.group(1)
            return extracted_text
        else:
            return None

# 示例用法
file_path = 'example.py'
start_string = '/*'
end_string = '*/'
extracted_text = extract_text_between_strings(file_path, start_string, end_string)
print(extracted_text)
