Python: how to concatenate two strings into a filename for shutil.copy

I have been struggling for a couple of hours trying to suss this out. I have parsed directories and files to find which files I want to copy to somewhere else. I have this:

Code:

for aFile in os.listdir(thispath):
	aPath = os.path.join(thispath, aFile)
	print aPath
	dest = thispath
	vs = thispath.split(rootdir).pop()
	dPath = os.path.join(destination_root,vs)
        print destination_root + vs
        print dPath

Although aPath is fine and

destination_root + vs

prints out correctly, dPath is just vs

vs is taking the Path of the files in the directory I'm copying and stripping out the start directory I am parsing from. So why doesn't this line:

dPath = os.path.join(destination_root,value)

Give me the same as destination_root + value ?

I want that to be right so I can use:

Code:

if os.path.isfile(aPath):	  
    shutil.copy(aPath,dPath)

Or maybe in other words how do I take a valid string and turn it into something shutil.copy will recognise as a valid directory?!

Hope that makes sense! Thanks

Ach, the problem was a leading / in the filename of the destination file. Stripping that out makes it work.
