Python 2.7 vs Python 3.4 ─ What should Python Beginners choose?
Codementor Python expert and Stack Overflow legend Martijn Pieters joined us for an Office Hours session, in which he provided some informative opinions about several issues asked by our viewers.
As Martijn’s used Python 3.4 in his demo, one of the questions asked was whether if there is a good reason for Python beginners to move from 2.7 to 3.4

Python 2.7 vs Python 3.4 ── What’s the difference and what should Python Beginners choose?
This really depends on what third-party libraries you rely on.
Personally, until Python 3.3 or 3.4, I would have stuck with Python 2.7, but I am now using Python 3.4 because of all the neat new features, and I think those changes will also make life easier for beginners. For example, the object-oriented path library and enumeration addition should be very helpful, and it’s not that difficult to switch over to Python 3. I think the Python developers have nailed the 3.x line, as it performs really well, and the interpreter uses history better than previous releases. Personally I really like the auto-completion features, which is why I used Python 3.4 in my demos. Moreover, Python 3.3. and 3.4 are getting all the developers’ attention, which means all the cool new additions are gathered in those versions, and they will be moving the ecosystem forward with the 3.x line. I believe 2.7 will be the last version for the 2.x series.
However, in Python 2.x a beginner won’t have to worry about all the implicit encoding and decoding issues that may arise when mixing byte strings and Unicode strings, so that may be something to consider.
The greatest difference between Python 2 and 3 is the libraries you use. If you are doing web development and use a lot of libraries that only support Python 2.x and have not yet been ported to Python 3.x, you might not have the same experience that makes Python so great.
In conclusion, beginners should have no problem switching over to Python 3, but if you are a beginner who depends on a lot of libraries that are 2.x only, then maybe it’s not such a great idea.
From the beginning until now I still can not understand about python
How simple way that I can understand about python?

I’m co-organizer of a local Python user group. We see our share of Python beginners. We recommend Python 3 to all beginners unless they have a specific reason to use Python 2. All of our group produced tutorial material is Python 3. If a beginner does have a need for using Python 2, we show them how to create a template for their Python files:
from future import absolute_import, division, print_function, unicode_literals
“However, in Python 2.x a beginner won’t have to worry about all the
implicit encoding and decoding issues that may arise when mixing byte
strings and Unicode strings, so that may be something to consider.”
On the other hand, Python 3.x doesn’t have the problematic division behavior, which is important if you are dealing with numerical programming.
Python 3.x wins!
