How to check if a directory is exist in python?

[yinglcs]

I check the documentation here, but it does not say how to check if a
directory is exist in python?
http://docs.python.org/lib/os-file-dir.html

And why mkdir fails if the directory already exists?

Thank you.

Check out os.path.isdir(path_name)

Look at the exist or isdir methods of the os.path module
(http://docs.python.org/lib/module-os.path.html}

If you prefer a "more friendly" approach you may wanna take a look at Trent
Mick's _mkdir which is located at

Ofcourse I mean "exists"...

You also mean "functions", not "methods". *Classes* have methods.
