How to check if file is a symlink in Python?

by

To determine if a directory entry is a symlink use this:

os.path.islink(path)

Return True if path refers to a directory entry that is a symbolic
link. Always False if symbolic links are not supported.

For instance, given:

drwxr-xr-x   2 root root  4096 2011-11-10 08:14 bin/
drwxrwxrwx   1 root root    57 2011-07-10 05:11 initrd.img -> boot/initrd.img-2..

>>> import os.path
>>> os.path.islink('initrd.img')
True
>>> os.path.islink('bin')
False
