Outdated Python...

[DarshanDash]

Hello everyone,

                         Here's the thing the other day i started watching TheNewBoston which was suggested by one of the  members here about Python i'm at lesson 7-8 right now at sequences and lists(Haven't got to that yet) Im done with expressions , inputs , strings but i feel shaky with it cause i have some issue with memorizing the commands (Why i suck at math).The weird thing i found out was some of bucky's videos were outdated according to the comments in his videos like raw_input doesnt exist anymore in python 3.x.x. so i'm lost right now should i continue learning or find an alternative method? I also kinda still confused with the idea with what you can do with coding cause there's so much i wanna know like Java,HTML, kotlin and more.Any professional programmer could give me a helping here?

thanks..

Raw input was replaced with input. Input assumes that the input is a string and makes it a string.

 

If you need input to be something else you need to convert it. 

 

#a string

Name = input ('enter name')

MyInt= int(input('enter int'))

So whats the fuss about it being outdated? Cause in worried if i might be learning old stuff instead of catching up with the latest trend

Well 2.7 is no longer being developed, people for a number of reasons cling to 2.7 be it from "I hate that print is a function" to code compatibility of the system the code runs one. 

 

If you're just starting to learn just learn python 3. For the most part the only thing you'll notice is what I posted above and some modules were renamed in py3.

 

Python 3 has some nice features such as generators.

Python 2.7 is still in active support, the last release was in September, and is slated to be supported until 2020.

 

However I'd argue that it was a dumb idea to make a new version and change a good chunk of keywords and built-ins such that it breaks compatibility with existing software.

was having this exact conversation today. Weird that. 

 

But yeah, I guess they just wanted it in a new way.

Then finish up then port your code to python. It's a good exercise

If they'd keep all the old syntax then it would become a massive mess (like C++).

And they even provide with some software to automate the conversion:

To the OP, continue learning Python 2. Most of it transfers to 3 if you decide you need to learn and use that later.

 

The transition from Python 2 to 3 is a mess. Especially if you use different software dependent on a particular version. But I guess that's what package managers like anaconda/miniconda are for. You can create environments for your Python 2 software and another for 3 and switch as needed. I do work in science and the transition to 3 is still ongoing.

One should always use the most current version of something unless there's a very good reason not to such as legacy support for example.

Sorry but that's terrible advice

Indeed, these are invaluable for dependency management, you should have a look here.

What are you hoping to get out of this, where do you most want to end up and what really drives you?

I'm interested in the rationale behind this. I have continued use of Python 2.7 because a few modules are not supported with 3.

Because you owe it to yourself if you actually care about what you're doing to keep current - always update when possible and feasible to do so.

Of course you have to be pragmatic, if there's something that's really needed then you have no choice...

But I'd be inclined to investigate every possible alternative first.
