 程序代码：# -*- coding: utf-8 -*- ''' Created on 01 30, 2016 @author: tolerious ''' import os,sys def scandir(startdir, target) : os.chdir(startdir) for obj in os.listdir(os.curdir) : if target in obj : print os.getcwd() + os.sep + obj if os.path.isdir(obj) : scandir(obj, target) os.chdir(os.pardir) if __name__ == "__main__": scandir(os.curdir,"test") 功能：在当前文件夹以及子文件夹下面找到包含所有"test" 字段的文件，并打印出其完整路径。 这是个递归调用、所以一定要搞清楚在什么情况下停止、以及“os.chdir(os.pardir)”这一步是很关键的、 |
练习：编写一个search(s)的函数，能在当前目录以及当前目录的所有子目录下查找文件名包含指定字符串的文件，并打印出完整路径：
$ python search.py test
unit_test.log
py/test.py
py/test_os.py
my/logs/unit-test-result.txt
我的是win10，代码如下：$ python search.py test
unit_test.log
py/test.py
py/test_os.py
my/logs/unit-test-result.txt
程序代码：#coding=utf-8
import os
def search(s, dir = '.'):
absPath = os.path.abspath('.')
for i in os.listdir(absPath):
# dir = os.path.join(absPath,i)
# print i,dir.decode('gbk')
if os.path.isdir(i):
dir2 = os.path.join(absPath, i)
search(s, dir2)
elif os.path.isfile(i) and s in i:
#pass
print absPath+i
if __name__ == '__main__':
search('.py')
但是一直提示错误：import os
def search(s, dir = '.'):
absPath = os.path.abspath('.')
for i in os.listdir(absPath):
# dir = os.path.join(absPath,i)
# print i,dir.decode('gbk')
if os.path.isdir(i):
dir2 = os.path.join(absPath, i)
search(s, dir2)
elif os.path.isfile(i) and s in i:
#pass
print absPath+i
if __name__ == '__main__':
search('.py')

一直没搞明白哪里错了File "E:/ѧϰ/Python/test/test.py", line 14, in search
