Lua was designed for this sort of thing and it can be secured and sandboxed.

If __iter__ raises, that's a bug :-)

For example in Python code you may want to instantiate some new instance

Running the following codes (deen.py) under Win32 python 3.4.4 terminal:
tbli = [0x66, 0x27, 0xD0]
tblm = [0 for x in range(3)]
def gpa(data):
td = data ^ tblm[2]
return td
I can get a correct answer this way:
>>> import deen
>>> deen.tblm = deen.tbli
>>> deen.gpa(0x7d)
173 # 0xad (= 0x7
In regards to performance of Lua vs Python, I don't have enough (near zero
experience) with Lua to comment there.
But in regards to embedding in a game, the only experience I have w/ Python
being embedded is while working on modding Civilization IV. What I saw
there just made me nauseous.

I don't think that's true. You can do a lot in Python without any imports in
your code:
- basic string processing
- BigNum (int) and float arithmetic
- lists and tuples

Below you can find my python code to make a vase for 3D-printing.
The vase looks nice on my screen so the vertices and the faces seem to be
perfect.
However, when sending the .stl file produced to a 3D-printer the vase comes out
as a filled solid - no room for water and flowers!

That's a way of finding out whether you can safely iterate
over something more than once. If the object is already an
iterator, applying iter() to it will return the same
object, and iterating over it will c

Hii there
I am preety New at python, and i need your help. I want to make a script that

don't know whether I really would use this form, but it works in python3:
