Actually, the Python Tutorial recommends the use of the 'with' statement
in Section 7.2.1. "Methods of File Objects":

> It is good practice to use the with keyword when dealing with file
> objects. [etc.]

But the example and description are at the very bottom of this very
large section, and are easily missed by new Python users.

If this suggestion is to be taken seriously, I suggest putting this
information at a more prominent place, somewhere at the top of the short
section 7.2. "Reading and Writing Files".

All the examples there assume that "a file object called f has already been created". Using a 'with' there it's not a good idea because the users will have to keep the instructions indented under the 'with'.
However I agree that it would be better to move that example earlier. Maybe in 7.2 both the forms can be shown and discussed briefly.

Good suggestion -- here's a patch that moves it and rewrites a little.

The patch looks good to me. I think we can tweak the content a bit. I left some comments on Rietveld.

Thanks!

Thanks everyone!
I merged the PR and backported to 3.6 and 3.5.

There are a bunch of conflicts when trying to backport to 2.7, so I decided not to bother.
