# -*- coding:utf-8*- import sys reload (sys) sys.setdefaultencoding( 'utf-8' ) import os import os.path import time time1 = time.time() ##########################合并同一个文件夹下多个txt################ def MergeTxt(filepath,outfile): k = open (filepath + outfile, 'a+' ) for parent, dirnames, filenames in os.walk(filepath): for filepath in filenames: txtPath = os.path.join(parent, filepath) # txtpath就是所有文件夹的路径 f = open (txtPath) ##########换行写入################## k.write(f.read() + "\n" ) k.close() print "finished" if __name__ = = '__main__' : filepath = "D:/course/" outfile = "result.txt" MergeTxt(filepath,outfile) time2 = time.time() print u '总共耗时:' + str (time2 - time1) + 's' |
运行结果:
"D:\Program Files\Python27\python.exe" D:/PycharmProjects/learn2017/合并多个txt.py
