Питонические атаки
I often find myself writing a context manager to temporarily change the current working directory:
import os
from contexlib import contextmanager
@contextmanager
def enter_dir(path):
old_path = os.getcwd()
os.chdir(path)
try:
yield
finally:
os.chdir(old_path)
Since Python 3.11, a context manager with the same behavior is available as contextlib.chdir:
import os
from contextlib import chdir
print('before:', os.getcwd())
# before: /home/gram
with chdir('/'):
print('inside:', os.getcwd())
# inside: /
print('after:', os.getcwd())
# after: /home/gram
