[Tutor] Directory or File ?

[Damien]

Hi all,
I want to know if a file is a directory or a simple file.
I have done a little ugly script :
# i is my filename, os is imported
old = os.getcwd()
try:
    chdir(i)
    is_dir = True
except:
    is_dir = False
os.chdir(old)
return is_dir

But maybe there is a better way ?
If you know a better way, please tell me.

Thanks,
Damien G.
