Brian, in case you remove previous directory - you will get the same exception that in the following code.

prev = os.chdir(somepath)
os.rmdir(prev)
os.chdir(prev)

Senthil, your arguments are strange. Both use cases are at least useful for me (if not intuitive). I also can't see how can I verify you assumptions by looking at the code. If you want to say that not every piece of code need to return to parent directory after chdir - that's pretty obvious. If you had a list of use cases for os.chdir() - I could go through them to mark where this can be used (or not).
