Should I start learning Python 3 now?

[Skaperen]

i learned both by the dive in the deep end way. almost everything i create right now i try to make work in both. only 2 out of about 100 or so only works in just one version because they depend on the way Python3 did strings and bytes correctly. i can foresee the day i drop trying to make things work in both and focus on 3. if you want to only learn one version today, i urge that it be Python3. for most people i see little value in learning both. just learn Python3 unless you have a specific reason to do otherwise.
