How do you make a forward slash in python?

I am working in python and I need to convert this:

C:\folderA\folderB to C:/folderA/folderB

I have three approaches:

dir = s.replace('\\','/') dir = os.path.normpath(s) dir = os.path.normcase(s)

In each scenario the output has been

C:folderAfolderB

I'm not sure what I am doing wrong, any suggestions?

I recently found this and thought worth sharing:

import os path = "C:\\temp\myFolder\example\\" newPath = path.replace(os.sep, '/') print(newPath) # -> C:/temp/myFolder/example/

Your specific problem is the order and escaping of your replace arguments, should be

s.replace('\\', '/')

Then there's:

posixpath.join(*s.split('\\'))

Which on a *nix platform is equivalent to:

os.path.join(*s.split('\\'))

But don't rely on that on Windows because it will prefer the platform-specific separator. Also:

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.

Try

path = '/'.join(path.split('\\'))

Path names are formatted differently in Windows. the solution is simple, suppose you have a path string like this:

data_file = "/Users/username/Downloads/PMLSdata/series.csv"

simply you have to change it to this: (adding r front of the path)

data_file = r"/Users/username/Downloads/PMLSdata/series.csv"

The modifier 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.

Sorry for being late to the party, but I wonder no one has suggested the pathlib-library.

pathlib is a module for "Object-oriented filesystem paths"

To convert from windows-style (backslash)-paths to forward-slashes (as typically for Posix-Paths) you can do so in a very verbose (AND platform-independant) fashion with pathlib:

import pathlib pathlib.PureWindowsPath(r"C:\folderA\folderB").as_posix() >>> 'C:/folderA/folderB'

Be aware that the example uses the string-literal "r" (to avoid having "\" as escape-char) In other cases the path should be quoted properly (with double backslashes) "C:\\folderA\\folderB"

To define the path's variable you have to add r initially, then add the replace statement .replace('\\', '/') at the end.

for example:

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

How about :

import ntpath import posixpath . . . dir = posixpath.join(*ntpath.split(s)) . .

This can work also:

def slash_changer(directory): if "\\" in directory: return directory.replace(os.sep, '/') else: return directory

print(slash_changer(os.getcwd()))

this is the perfect solution put the letter 'r' before the string that you want to convert to avoid all special characters likes '\t' and '\f'... like the example below:

str= r"\test\hhd" print("windows path:",str.replace("\\","\\\\")) print("Linux path:",str.replace("\\","/"))

result:

windows path: \\test\\hhd Linux path: /test/hhd
