file_path = 'D:/50425-20220108101800-20220108114459-0.txt'
remove_first_three_lines(file_path)

结果：

 如果是文件夹内的所有txt：

import osdef remove_first_three_lines(file_path):"""删除文件的前三行并保存原文件。:param file_path: 文件路径"""with open(file_path, 'r', encoding='utf-8') as file:lines = file.readlines()# 去掉前三行if len(lines) > 3:lines = lines[3:]else:lines = []  # 如果文件行数少于3行，则清空文件内容
