A pattern I find myself using frequently, when I do need to “cd”, is to write a
tiny context manager:
```
import os
from contextlib import context manager
@contextmanager
def pushd(path):
old_dir = os.getcwd()
os.chdir(path)
try:
yield
finally:
os.chdir(old_dir)
```
(I tend to just copy this into projects where I need it (or write it again), as
a whole dependency for something so tiny seems like it would be overkill :)
