If for any reason you need to provide the paths yourself and you have using anything above python 3.4 you can use pathlib

from pathlib import Path, PurePosixPath

a = PurePosixPath('c:/')
b = PurePosixPath('myFirstDirectory/')
c = 'mySecondDirectory'
d = 'myThirdDirectory'
e = 'myExecutable.exe'

print(a / b / c / d / e)

# Result
c:/myFirstDirectory/mySecondDirectory/myThirdDirectory/myExecutable.exe

I used this when I needed a user to provide the location of an assets directory and my code was looking up using windows path strings

In [1]: from pathlib import Path, PureWindowsPath
In [2]: USER_ASSETS_DIR = Path('/asset/dir') # user provides this form environment variable
In [3]: SPECIFIC_ASSET = PureWindowsPath('some\\asset')
In [4]: USER_ASSETS_DIR / SPECIFIC_ASSET

Out[4]: PosixPath('/asset/dir/some/asset')
