New submission from Trey Hunner <[email protected]>:
The below code worked on Python 3.5, 3.6, 3.7, and 3.8, but it now crashes on
Python 3.9.
from contextlib import contextmanager
@contextmanager
def open_files(names):
yield names # This would actually return file objects
with open_files(['file1.txt', 'file2.txt']) as (first, *rest):
print(first, rest)
The error shown is:
with open_files(['file1.txt', 'file2.txt']) as (first, *rest):
^
SyntaxError: invalid syntax
