Python 3 vs Python 2

Question

there are several deferences between 2 and 3 of Python. I was with 2 for 2 months. and now I am confused. Some are good. But some

Answer 1

@Harshana Look for QPython3.
The name says it all :)

Answer 2

What specifically confuses you?
It is best to focus on python 3 as python 2 will not really be ever updated again(except for 3rd party modules which may provide updates to themselves)
Saying that however there is still a lot of python 2 code that you may have to work with or maintain in the future.
Many changes that get slightly annoying are module names. In python 2 some modules such as ConfigParser are now configparser(lowercase which match the pep8 standard)
Is there anything in particular you are having issues with?

The unicode things gets me all the time! but luckily simple changes make it backwards compatible. I have a few programs that have had to be python 2.6, 2.7 and 3+ compatible.

Answer 4

Nope. I have python android app. it is python 2. and I can not find a android app for python 3.

Answer 5

I am not worrying about modules. its just some basic keywords

Answer 6

the difficulty i see is so many programs utilizing python used 2 and aren't compatible with python 3. if doing new code try to stick with 3 if nothing just to be part of the solution not the problem ,but in general you'll need to have both versions available ,for now

Answer 7
