Moving files under python

Question

I'm confused with file moving under python. Under windows commandline, if i have directory c:\a and a directory c:\b, i can do

move c:\a c:\b

which moves a to b result is directory structure c:\b\a

If I try this with os.rename or shutil.move:

os.rename("c:/a", "c:/b")

I get

WindowsError: [Error 17] Cannot create a file when that file already exists

If I move a single file under c:\a, it works.

In python how do i move a directory to another existing directory?

Answer 1

os.rename("c:/a", "c:/b/a") 

is equivalent to

move c:\a c:\b

under windows commandline
