bat 正则换行 如何撰写？-灵析社区

用python怎么样 replace.py import re import os import sys def handle(folder_path): if not os.path.exists(folder_path): print("{} 为无效路径".format(folder_path)) return # 按顺序执行正则替换,可自行添加正则 pattern_replacements = [[r'[「」【】]',''], [r'(.{6,18}[，。：！？]|.{16})',r'\1\r\n'], [r'[，。！]',''], [r'[\r\n]+','\n']] data = '' for file in os.listdir(folder_path): file_path = os.path.join(folder_path,file) if not os.path.isdir(file_path) and file_path.endswith('.txt'): with open(file_path,'r',encoding='utf-8') as fr: data = fr.read() for pattern,replacement in pattern_replacements: data = re.sub(pattern,replacement,data) with open(file_path,'w',encoding='utf-8') as fw: fw.write(data) print("{} 处理完成".format(file)) print("全部处理完成") if __name__ == "__main__": folder_path = r"d:\txt" if len(sys.argv) > 1: folder_path = sys.argv[1] handle(folder_path) start.bat @echo off set "folderPath=D:\txt\" REM 检查系统环境变量中是否存在Python路径 where python > nul 2>&1 if %errorlevel% equ 0 ( REM Python路径已添加到系统环境变量中 set "python_path=python" ) else ( REM Python路径未添加到系统环境变量中,需手动设置Python路径,以下为测试路径 set "python_path=D:\Env\Python\Python38\python.exe" ) %python_path% replace.py %folderPath% || pause pause 把start.bat和replace.py放到同一个文件夹,配置下python路径就可以执行批处理文件了
