Question

I am trying to create a function that will take in a list of paths (from the parameter list), execute several functions from os.path on it (expandvars, expanduser, normpath), and finally join all those path values. So far it looks like this:

def normjoin(*p):
    """ Uses os.path functions to normalize and join paths
       *path - all the paths you want to join
       return: normalized and joined string
    """
    b_results = []
    for b in p:
        b_results.append(os.path.normpath(os.path.expandvars(os.path.expanduser(b))))
    return os.path.join(b_results)

And this is how it looks in practice:

sharedir = normjoin("~", "Dropbox/SpideroakShared")

I plan to use this on both a win and linux system.

The return value will come looking like this ' "C:\\Users\\tgoldie", "Dropbox\\SpideroakShared"' which is not good.

Any ideas?

The body of the function should be indented.

You have b_results = "", but then try to append. That won’t work. You need b_results = [].

Finally, you need to pass the items of b_results as arguments to os.path.join like this:

return os.path.join(*b_results)
