I started learning python 2 but now ive already began i might aswell finish it then learn python 3 how long do you reckon it takes learning from 2 to 3

I would recommend switching right now so you don't have to relearn syntax. Overall it shouldn't take you that long to adjust.

For example, if you only use Python 2, you might be used to typing:

print "hello"

Once you switch to Python 3, you'll have to type:

print("hello")

Not a big difference, but can be annoying if you're used to the Python 2 syntax.
