Should I learn python3 or Python?

Should I learn python3 or Python?

In the past, there was a bit of a debate in the coding community about which Python version was the best one to learn: Python 2 vs Python 3 (or, specifically, Python 2.7 vs 3.5). Now, in 2018, it’s more of a no-brainer: Python 3 is the clear winner for new learners or those wanting to update their skills.

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

In python 2. x, “print” is treated as a statement and python 3. x explicitly treats “print” as a function. This means we need to pass the items inside your print to the function parentheses in the standard way otherwise you will get a syntax error.

Do I have Python 2 or 3?

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 version of Python should I learn in 2021?

It is wise to go with the latest trend and what is in demand. The only reason to learn Python 2 would be if a job demand requires specific knowledge in Python 2. But that would rarely be the case. If you are not sure, just stick with Python 3.

Can I still use Python 2?

Should I learn Python 2 or 3 first?

Very soon there will be no future security or bug fixes for Python 2.x, and your time is better spent learning 3.x. In the unlikely event that you end up working with a legacy Python 2 code base, tools like python-future will make it easy for you to use having only learned Python 3.

Do you really need to learn all of Python syntax?

Most tutorials and Python courses assume that you need to learn all of Python syntax before you can start doing anything interesting. This is what leads to months spent just on syntax, when what you really want to be doing is analyzing data, or building a website, or creating an autonomous drone.

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 purpose of Python 3 syntax?

The purpose of Python 3 syntax was to prevent redundant or repetitive code—code that essentially does the same tasks in different ways. Python 3.X aims to procure only one, clear way of doing things. For novice programmers, this immediately discards the main problems that occur when learning a programming language.
