Python Convert Back Slashes to forward slashes
提问by John87
I am working in python and I need to convert this:
我在 python 中工作，我需要转换它：
C:\folderA\folderB to C:/folderA/folderB
C:\folderA\folderB 到 C:/folderA/folderB
I have three approaches:
我有三种方法：
dir = s.replace('\','/')
dir = os.path.normpath(s)
dir = os.path.normcase(s)
In each scenario the output has been
在每种情况下，输出都是
C:folderAfolderB
C:folderAfolderB
I'm not sure what I am doing wrong, any suggestions?
我不确定我做错了什么，有什么建议吗？

Your specific problem is the order and escaping of your replacearguments, should be
你的具体问题是你的replace论点的顺序和转义，应该是
s.replace('\', '/')
Then there's:
然后是：
posixpath.join(*s.split('\'))
Which on a *nix platform is equivalent to:
在 *nix 平台上相当于：
os.path.join(*s.split('\'))
But don't rely on that on Windows because it will prefer the platform-specific separator. Also:
但是不要在 Windows 上依赖它，因为它会更喜欢特定于平台的分隔符。还：
Note that on Windows, since there is a current directory for each drive, os.path.join("c:", "foo") represents a path relative to the current directory on drive C: (c:foo), not c:\foo.
请注意，在 Windows 上，由于每个驱动器都有一个当前目录，因此 os.path.join("c:", "foo") 表示相对于驱动器 C: (c:foo) 上的当前目录的路径，而不是 c :\foo.

How about :
怎么样 ：
import ntpath
import posixpath
.
.
.
dir = posixpath.join(*ntpath.split(s))

To define the path's variable you have to add rinitially, then add the replace statement .replace('\\', '/')at the end.
要定义路径的变量，您必须首先添加r，然后.replace('\\', '/')在最后添加替换语句。
for example:
例如：
In>> path2 = r'C:\Users\User\Documents\Project\Em2Lph\'.replace('\', '/')
In>> path2
Out>> 'C:/Users/User/Documents/Project/Em2Lph/'
This solution requires no additional libraries
此解决方案不需要额外的库

I recently found this and thought worth sharing:
我最近发现了这个并认为值得分享：
import os
path = "C:\temp\myFolder\example\"
newPath = path.replace(os.sep, '/')
print newPath
Output:<< C:/temp/myFolder/example/ >>

Path names are formatted di?erently in Windows. the solution is simple, suppose you have a path string like this:
路径名在 Windows 中的格式不同。解决方案很简单，假设你有一个这样的路径字符串：
data_file = "/Users/username/Downloads/PMLSdata/series.csv"
simply you have to change it to this: (adding r front of the path)
只需将其更改为：（在路径前添加 r ）
data_file = r"/Users/username/Downloads/PMLSdata/series.csv"
The modi?er r before the string tells Python that this is a raw string. In raw strings, the backslash is interpreted literally, not as an escape character.
字符串前的修饰符 r 告诉 Python 这是一个原始字符串。在原始字符串中，反斜杠按字面解释，而不是转义字符。
