pushd for Python

pushd.py

from os import chdir, getcwd
from os.path import realpath

class PushdContext:
    cwd = None
    original_dir = None

    def __init__(self, dirname):
        self.cwd = realpath(dirname)

    def __enter__(self):
        self.original_dir = getcwd()
        chdir(self.cwd)
        return self

    def __exit__(self, type, value, tb):
        chdir(self.original_dir)

def pushd(dirname):
    return PushdContext(dirname)

# Example use
with pushd('./anfplaylists') as ctx:
    print(ctx.cwd, ctx.original_dir)
print(getcwd())

Thanks, nice.
what is the function pushd for? Doesn't with PushdContext(PATH) do the same? And why do you implement cwd and originaldir as class members? Doesn't that conflict when you use that class in a nested way?

Awesome, this should be in the standard lib os module.

Does anyone know why is pushd and popd not included in the python's standard os module yet?
