Если ты хочешь запустить код с изменённой глобальной переменной, лучше использовать контекстный менеджер, а не менять её напрямую:


from contextlib import contextmanager

QUIT_MESSAGE = 'Bye'

def print_quit_mesage():
global QUIT_MESSAGE
print(QUIT_MESSAGE)

@contextmanager
def global_variable_changed(name, value):
orig_value = globals()[name]
globals()[name] = value
yield
globals()[name] = orig_value

with global_variable_changed(
'QUIT_MESSAGE',
'Tschüss'
):
print_quit_mesage()
