windows上的python文件名 [英] python filename on windows

问题描述

免责声明我有一个类似的帖子，但我认为它太大了，太复杂了

Disclaimer I have a similar thread started but I think it got too big and convoluted

简而言之，这就是问题

import imghdr
import os.path
....
image_type = imghdr.what(os.path.normpath(filename))

失败

IOError: [Errno 22] invalid mode ('rb') or filename: 'D:\\mysvn\\trunk\\Assets\\models\\character\\char1.jpg\r'

上述文件存在的地方

帮助?:D

推荐答案

文件名末尾有一个回车符\r.这不是 Windows 文件名的有效字符，所以我怀疑文件名是否有效.

There is a carriage return character \r at the end of the filename. That is not a valid character for a Windows filename, so I doubt the filename will work.

使用 .rstrip('\r') 删除它:

image_type = imghdr.what(os.path.normpath(filename.rstrip('\r')))

.rstrip() 从字符串的末尾删除字符，并且只删除您命名的集合中的字符.

.rstrip() removes characters from the end of a string, and only those in the set that you name.

因为这是一个文件名，文件名周围的任何空格可能是不正确的，所以直接的 .strip() 也可以:

Since this is a filename, any whitespace around the filename is probably incorrect, so a straight-up .strip() would work too:

image_type = imghdr.what(os.path.normpath(filename.strip()))

这会从字符串的开始和结尾删除制表符、换行符、回车符和空格.

This would remove tabs, newlines, carriage returns and spaces from both the start and end of the string.
