I was wondering if there were any neat tools (like for instance,
something from itertools) that would help me write the following function
more elegantly. The return value should, of course, be the complete $k$-

Not sure exactly how you're representing graphs, this seems like the

I chose not to consider that case, since they were the same length in the
original post. Based on the variable names, it seemed reasonable that
there would always be a 1-to-1

In the language documentation, all that is said about thread.error is

Bastion and rexec have been deprecated since Python 2.2, so it seems
we (the Python community) have gotten along well enough without them.
Have these modules not been reimplemented because:
a) There are no valid use cases for them.
b) Doing so would be difficult and prone to breakage as new

I see lambda is going away, so I want to use something that will be
around for awhile.
All I want to do is provide an inline function as an argument to
another function.
For example, let's say I have a function which binds a key to a function
call. I want to do something simple in this

Yeah, I'm using lamda now it works nicely/cleanly.
If a lot of the bindings are actually setting variables, you could do
