# -*- 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

总共耗时:0.000999927520752s

希望本文所述对大家Python程序设计有所帮助。
