This is a problem I sometimes run into when working with a lot of files simultaneously, where I need three or more with statements: with open('foo') as foo: with open('bar') as bar: with open('baz') as baz: pass Thankfully, support for multiple items was added in 3.1: with open('foo') as foo, open('bar') as bar, open('baz') as baz: pass However, this begs the need for a multiline form, especially when working with three or more items: _with open('foo') as foo, _ _open('bar') as bar, _ _open('baz') as baz, _ _open('spam') as spam _ open('eggs') as eggs: pass

I generally see this kind of construct as a sign that refactoring is needed. For example, contextlib.ExitStack offers a number of ways to manage multiple context managers dynamically rather than statically.
