Example

The following example shows the usage of readlink() method.

# !/usr/bin/python
import os

src = '/usr/bin/python'
dst = '/tmp/python'

# This creates a symbolic link on python in tmp directory
os.symlink(src, dst)

# Now let us use readlink to display the source of the link.
path = os.readlink( dst )
print path

Let us compile and run the above program, this will create a symblic link to /usr/bin/python and later it will read the source of the symbolic link using readlink() call. Before running this program make sure you do not have /tmp/python already available.

/usr/bin/python
