os.path.join producing an extra forward slash

I am trying to join an absolute path and variable folder path depending on the variable run. However when I use the following code it inserts a forward slash after a string, which I don't require. How can I remove the slash after Folder_?

import os
currentwd = os.getcwd()
folder = '001'
run_folder = os.path.join(currentwd, 'Folder_', folder)
print run_folder

The output I get using this code is:

/home/xkr/Workspace/Folder_/001

You are asking os.path.join() to take multiple path elements and join them. It is doing its job.

Don't use os.path.join() to produce filenames; just use concatenation:

run_folder = os.path.join(currentwd, 'Folder_' + folder)

or use string formatting; the latter can give you such nice features such as automatic padding of integers:

folder = 1
run_folder = os.path.join(currentwd, 'Folder_{:03d}'.format(folder))

That way you can increment folder past 10 or 100 and still have the correct number of leading zeros.

Note that you don't have to use os.getcwd(); you could also use os.path.abspath(), it'll make relative paths absolute based on the current working directory:

run_folder = os.path.abspath('Folder_' + folder)
