我建​​议像string.maketrans
http://docs.python.org/lib/node41.html 。我不记得

它是如何工作的，但我认为它类似于

>> invalid_chars =" abc"
replace_chars =" 123"
char_map = string.maketrans（invalid_chars，replace_chars）
filename = " abc123.txt"
filename.translate（charmap）

''123123.txt''

你好我正在编写一个python脚本，用户创建目录

输入。

有时候用户输入的字符不是

文件或目录名称的有效字符。

以下是我认为有效字符的字符...


有效=

''：。/ ,^ 01 23456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKL MNOPQRSTUVWXYZ''


如果我有一个名为fname的字符串我想要浏览

中的每个字符文件名，如果它不是有效字符，然后我想用空格替换

。


这就是我所拥有的：


def fixfilename （fname）：

有效=

''：。\，^ 0123456789abcdefghijklmnopqrstuvwxyzABCDEFGH IJKLMNOPQRSTUVWXYZ''

for i in range（len（fname） ））：

if valid.find（fname [i]）< 0：

fname [i] =''''

返回fname


有人想到更简单的解决方案吗？

如果你想剥离''em：

>> valid =''：。/ ,^ 0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKL MNOPQRSTUVWXYZ''
filename =''！"£！£

" ;

Hi I''m writing a python script that creates directories from user
input.
Sometimes the user inputs characters that aren''t valid characters for a
file or directory name.
Here are the characters that I consider to be valid characters...

valid =
'':./,^0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKL MNOPQRSTUVWXYZ ''

if I have a string called fname I want to go through each character in
the filename and if it is not a valid character, then I want to replace
it with a space.

This is what I have:

def fixfilename(fname):
valid =
'':.\,^0123456789abcdefghijklmnopqrstuvwxyzABCDEFGH IJKLMNOPQRSTUVWXYZ ''
for i in range(len(fname)):
if valid.find(fname[i]) < 0:
fname[i] = '' ''
return fname

Anyone think of a simpler solution?

I would suggest something like string.maketrans
http://docs.python.org/lib/node41.html. I don''t remember exactly how
it works, but I think it''s something like

>>invalid_chars = "abc"
replace_chars = "123"
char_map = string.maketrans(invalid_chars, replace_chars)
filename = "abc123.txt"
filename.translate(charmap)

''123123.txt''

If you want to strip ''em:

>>valid='':./,^0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKL MNOPQRSTUVWXYZ ''
filename = ''!"￡!￡
