Wheezy is no longer supported by Debian. It's not even oldstable any
more. But if you still have old releases sitting around, you have two
good options:

1) Use IDLE from CPython 3.2 by installing package idle3
2) Compile CPython 3.5+ from source

But if you have issues with networking on Stretch, just uninstall
Network Manager and try again. I've been using Stretch since before it
was stable, and have not a whit of trouble. All my family use either
Debian or Ubuntu (including the not-so-technically-literate ones), and
those on Debian are mostly on Stretch. That includes laptops that
connect to various different wifi networks, the routers/gateways that
drive the networks themselves, everyone's desktop computers... the
works.

Also, that *still* has nothing to do with the matter at hand. There's
no problems running some version of IDLE on any release of Debian that
I've ever used.

Okay, but I'm trying to understand why you're referencing this in this
thread about indentation. That would imply that you at least have
reason to suspect that the problem is indentation.
