找不到Python档案错误 [英] Python File not found error

问题描述

我有一个包含不同子文件夹的文件夹.我必须遍历所有文件并检查John和Jose的出现，并分别替换为Mikel和Mourinho.

I have a folder with different subfolders in it. I have to iterate through all the files and check for the occurrences of John and Jose and replace with Mikel and Mourinho respectively.

这是我用Python编写的脚本.它工作正常，但是当我遇到.gif文件时，这给了我一个错误，并且没有进行进一步的迭代.

This is the script I have written in Python. It is working fine but when I encounter a .gif file it is giving me an error and it is not iterating further.

你能告诉我为什么吗?

错误是

Traceback (most recent call last):
  File "C:\Users\sid\Desktop\script.py", line 33, in <module>
    os.chmod(path ,stat.S_IWRITE)
FileNotFoundError: [WinError 2] The system cannot find the file specified:'C:\Users\sid\Desktop\test\\images/ds_dataobject.gif.bak'

我的代码:

import os,stat
import fileinput
import sys

rootdir ='C:\Users\spemmara\Desktop\test'
searchTerms={"John":"Mikel", "Jose":"Mourinho"}

def replaceAll(file,searchExp,replaceExp):
    for line in fileinput.input(file, inplace=1):
        if searchExp in line:
            line = line.replace(searchExp,replaceExp)
        sys.stdout.write(line)

for subdir, dirs, files in os.walk(rootdir):
    for file in files:
        path=subdir+'/'+file
        print(path)
        os.chmod(path ,stat.S_IWRITE)
        for key,value in searchTerms.items():
            replaceAll(path,key,value)
        os.chmod(path,stat.S_IREAD)

推荐答案

使用原始字符串或双斜杠\\:

Use a raw string or Double blackslashes \\:

没有\\或原始字符串'\t'都将转换为制表符空间:

Without \\ or raw string '\t' is converted to a tab space:

>>> print 'C:\Users\spemmara\Desktop\test'
C:\Users\spemmara\Desktop   est

带有原始字符串:

>>> print r'C:\Users\spemmara\Desktop\test'
C:\Users\spemmara\Desktop\test

双反斜杠:

>>> print 'C:\\Users\\spemmara\\Desktop\\test'
C:\Users\spemmara\Desktop\test

更新:

'C:\ Users \ sid \ Desktop \ test \ images/ds_dataobject.gif.bak'

'C:\Users\sid\Desktop\test\images/ds_dataobject.gif.bak'

查看您尝试在单个路径中混合\和/的错误，最好使用os.path.join:

Looking at the error you're trying to mix \ and / in a single path, better use os.path.join:

path = os.path.join(subdir, file)
