[Python-ideas] with statement syntax forces ugly line breaks?

[Mark Summerfield]

Hi,

I can't see a _nice_ way of splitting a with statement over mulitple
lines:

class FakeContext:
    def __init__(self, name):
        self.name = name
    def __enter__(self):
        print("enter", self.name)
    def __exit__(self, *args):
        print("exit", self.name)

with FakeContext("a") as a, FakeContext("b") as b:
    pass # works fine


with FakeContext("a") as a,
     FakeContext("b") as b:
    pass # synax error


with (FakeContext("a") as a,
      FakeContext("b") as b):
    pass # synax error

The use case where this mattered to me was this:

    with open(args.actual, encoding="utf-8") as afh,
    open(args.expected, encoding="utf-8") as efh: actual =
    [line.rstrip("\n\r") for line in afh.readlines()] expected =
    [line.rstrip("\n\r") for line in efh.readlines()]

Naturally, I could split the line in an ugly place:

    with open(args.actual, encoding="utf-8") as afh, open(args.expected,
	    encoding="utf-8") as efh:

but it seems a shame to do so. Or am I missing something?

I'm using Python 3.1.2.
