I think this sticks strictly to the KISS principle, keeping it simple,

bugs and complications.
And it matchs perfectly webpy's philosofy for creating web apps.

So it comes as no surprise that the distribution has a lot of

Also, and as far as I know, the use of python is encouraged for making

So going back to your question, you should have two lists, as follows:
n = ['a', 'm', 'p']
v = [1,3,7] --> note that I used brackets [], not curly
braces {}.
And now you can build a dict formed by the keys in "n" and the values
in "v":
myDict = {} --> this is an new empty dictionary
for k,v in zip(n,v):
myDict[k] = v
This results in this dictionary: {'a': 1, 'p': 7, 'm': 3}.
Hope this helps...

I see Lua as a some sort of minimal Python. It looks like a simplified
subset of python.
Being simpler, it's also easier to implement efficiently. Note that
Lua was created a simple language to be embedded into larger
applications written in c or c++. So it doesn't need a standard
library, since you would be using libraries built for the main
aplication, written in c or c++.
However it worth noting that, according to Mike Pall (the creator of
Luajit), there's no reason to believe Python could not be as fast a
Luajit. It has no show stoppers. It would simply require much more
work around its corner cases, being the main difficulties in python's
own environment, not in the core language.
This is all explained in the above mentioned thread on tracing jits...
