从文本文件中单独处理特定模式边界中的代码行？

import re

def process_code_lines(file_path, start_pattern, end_pattern):
    with open(file_path, 'r') as file:
        code_lines = []
        is_inside_boundary = False

        for line in file:
            if re.search(start_pattern, line):
                is_inside_boundary = True
            elif re.search(end_pattern, line):
                is_inside_boundary = False

            if is_inside_boundary:
                code_lines.append(line.strip())

        # 在这里对code_lines进行单独处理，可以根据需求进行相应的操作

        return code_lines

# 示例用法
file_path = 'example.txt'
start_pattern = r'^START$'
end_pattern = r'^END$'
processed_lines = process_code_lines(file_path, start_pattern, end_pattern)
print(processed_lines)
