python 中的正向/反向斜线问题

Question

I am having a problem setting a new string to os.chdir (to change directory).

fullDir= '//user/Tester/diagnostics/data/'
fullDirString= fullDir+ uniqueName + '/' + folderNameRun
os.chdir(fullDirString)

Error code I get is "FileNotFoundError: [WinError 3] System cannot find the path specified

I have tried this to fix that issue

fullDir= '\\user\Tester\diagnostics\data\'
fullDirString= fullDir+ uniqueName + '\' + folderNameRun
os.chdir(fullDirString)

And I have tried this

newfullDirString= fullDirString.replace('\\', r'\')   

However I am out of luck. Any advice?

Answer 1

What about using os.path module? It should take care about the path construction depending on the current OS

from os import path
fullDir = '//user/Tester/diagnostics/data/'
fullDirString= path.join(path.normpath(fullDir),uniqueName,folderNameRun)
os.chdir(fullDirString)

Edit 1:

Integrated the path.normpath to normalize the initial path, as suggested by @zmike
