I have started to learn Python 3. I am very new to python, but am familiar with VB script. So some of the Python 3 syntax is making sense to me.

However, I have been reading about Python 2, and it seems many people still use it.

So my first question is.

Should I learn Python 2 and then learn Python 3?

Or, am I ok sticking with Python 3 for now.

I want to learn Python, for Iphone programming and script writing.

Also, I heard that python is useful for PEN testing. I assume however, that most PEN testers use python 2. Since it's been around much longer.
 

Thank you for your reply, I will stick with Python 3 then for now. I really like the syntax so far in python 3, It's very "logical"

tturner, I don't see how that is relevant. People write in the code they know. I'd rather make my security tools in Shell script and Perl.

If you're running other people's code than yeah, go with the interpreter that works for that code. But if you're writing fresh might as well go with the one that's maintained, and the developers are trying to get people to switch too.

Not dissing you, have respect, but I can't agree with you on this.

tturner, all good. that's a better argument. Showing you're using existing code to learn and do more.

Wasn't trying to knock you man. Just didn't see where you were coming from.
