It's great that multiple context managers can be sent to "with":

with a as b, c as d, e as f: suite If the context mangers have a lot of text it's very hard to comply with PEP8 without resorting to "" continuations, which are proscribed by the Google style guide. Untrue. " Backslashes may still be appropriate at times. For example, long, multiple with -statements cannot use implicit continuation, so backslashes are acceptable:

Where are you looking at that? The one I see is here:

https://google-styleguide.googlecode.com/svn/trunk/pyguide.html#Line_length

Explicitly says:

Exceptions:

Do not use backslash line continuation.

_with open('/path/to/some/file/you/want/to/read') as file1, _ open('/path/to/some/file/being/written', 'w') as file2: file2.write(file1.read())" Other statements like import and if support enclosing their arguments in parentheses to force aligned continuations. Can we have the same for "with"?

No. Considered and rejected because it would not be trivial. If your argument is the amount of work, I might be able to find the time to do the work if someone will promise to review it quickly. I think it's not more than an afternoon to modify cpython.
