The syntax error is coming from finding "as" in a place it's unexpected. (Additionally, if you were to drop the `as fn`, you'd get an AttributeError as tuple.__enter__ isn't defined).
There's a contextlib helper that you might consider: https://docs.python.org/3/library/contextlib.html#contextlib.ExitStack Which you might use like: from contextlib import ExitStack with ExitStack() as stack: f1 = stack.enter_context(open(fname1)) f2 = stack.enter_context(open(fname2)) f3 = stack.enter_context(open(fname3)) f4 = stack.enter_context(open(fname4)) ...
