Which version is better for Python?

Version 2.7. 9 will be the best choice because the tutorial which are available on the internet are mostly of Python 2 language and very few of Python 3. Once you get to know about Python 2, it will not be difficult for you to switch to Python 3.

Is it worth learning Python 2?

No. At least not at first anyway. Everyone learning Python should learn and use Python 3, preferably Python 3.6 or later. If you find that for some bizarre reason you need to use Python 2, it is very easy to deal with that situation.

How do I know if my code is Python2 or Python3?

If you want to determine whether Python2 or Python3 is running, you can check the major version with this sys. version_info. major . 2 means Python2, and 3 means Python3.

What is the difference between Python 2 x and 3 Xrange?

So Python 3.x’s range function is xrange from Python 2.x. There is a small change in error handling in both versions. In python 3.x, ‘as’ keyword is required. This is basically not a difference between the two versions, but a useful thing to mention here. The idea of the __future__ module is to help migrate to Python 3.x.

What is the difference between Python 2 and Python 3?

It is recommended to use either float (x) instead of using only x in your python 3 code (incase codebase port to python 2) or use from __future__ import division in your python 2 scripts. 3. Unicode Strings By default, Python 3 stores strings as Unicode whereas Python 2 requires you to mark a string with a “u” if you want to store it as Unicode.

What is the difference between Python 2 and Python 3 exceptions?

Python 3 exceptions should be enclosed in parenthesis while Python 2 exceptions should be enclosed in notations. Python 3 rules of ordering comparisons are simplified whereas Python 2 rules of ordering comparison are complex. Python 3 offers Range () function to perform iterations whereas, In Python 2, the xrange () is used for iterations.

What is the syntax of Python 2?

The syntax of Python 2 was comparatively difficult to understand. In this version, Rules of ordering comparisons have been simplified. Rules of ordering comparison are very complex. The new Range () function introduced to perform iterations. In Python 2, the xrange () is used for iterations.
