Great but what does it do

Great but what does it do

It does whatever you set it to do. Python is an interpreted programming language.
It adds a new layer of abstraction to B4A, so in other words, it's one more tool in our toolbox.

Sorry I did not explain well. I know what Phyton is, but I want to know what the code is .... is a phyton interpreter written in B4A?

 

[DonManfred]

is a phyton interpreter written in B4A?

it is a python interpreter library. I dont think it is written in B4A but it can be used in B4A ;-)

 

[Star-Dust]

That's really interesting.
is 100% compatible or are you currently working for?

Oops, it seems that I forgot to clarify on the first post, that you'll need the python zip files found in the Demo Project.
Please copy them to your Files folder and give it another try.

EDIT: First post updated.

Please copy them to your Files folder and give it another try.

sorry but still the same error

 

[wonder]

Can you send me your B4A project?
