Python Course - Lesson 2 - Installing Python - eXcript

How to install Python? Where to download Python? You'll learn the answers to these and many other questions in this lesson! Installing Python is relatively easy. In fact, if you've already installed other programs on Windows, you'll be able to install Python very easily. However, if you have any difficulties, this lesson aims to help and guide you step-by-step through the installation.

======================
To download Python, you can download it from the following link:
https://www.python.org/downloads/
It is necessary to pay attention to downloading the installation package according to the operating system you are using and also choose between the 32-bit or 64-bit version. If you are using Windows 8 or higher, you are on a 64-bit architecture. Otherwise, you will have to find out which architecture you are working with.
If in doubt, leave a comment or read the comments from others. Most likely someone has already had a similar problem to yours, and a quick look at our colleagues' comments can save you hours of headaches!
== LINUX USERS / OTHER DISTROS ==
This lesson did not cover the installation of Python on other operating systems. MAC users already have Python, and most major Linux distributions also have Python pre-installed.
WHAT'S THE PROBLEM THEN?
The version of Python that is installed. In this course, we work with Python version 3, but most operating systems come with Python 2.7 pre-installed.
WHAT IS THE REASON FOR HAVING TWO VERSIONS, 2.7.xxxx AND 3.xxx.xxx?
Python version 3 underwent significant structural changes; the simplest, we can say, is the fact that you are now required to use parentheses in the 'print()' function. However, this is just one change; there are several others, mainly in the object-oriented programming area.
To avoid major incompatibility problems, it was decided to use two versions of Python in parallel: version 2.7 and version 3. Python 2.7 supports most of the changes in Python 3, but the reverse is not true. That is, Python 3 does not support Python 2.7.
WHAT IS IMPORTANT TO KNOW?
That there are 2 OFFICIAL versions: version 2.7 and version 3. Version 2.7 is the one that will be discontinued in 2022 and it has been gradually undergoing several modifications. Thus, what happens is that there will not be a drastic change, but rather, version 2.7 will coexist with version 3.
With each new version of Python 2.7, it brings new features that are already in Python 3. Therefore, both versions progress together and in parallel at the same time. Code-level changes are implemented in both versions; however, as already mentioned, version 2.7 does not work in version 3.
WHAT IS MY PYTHON VERSION?
Go to the command prompt/shell/bash and type:
... python
If nothing happens, try typing only the word:
... py
The text you should see should be similar to the following:
... python
Python 3.4.3 (default, Mar - YYYY, hh:mm:ss) [MSC v.1600 64 bit (AMD64)] on win32
Type "copyright", "credits" or "license()" for more information.
OR:
... python
Python 3.4.3 |Anaconda 2.2.0 (64-bit)| (default, Mar YYYY, hh:mm:ss) [MSC v.1600 64 bit (AMD64)] on win32
Type "copyright", "credits" or "license()" for more information.
WHAT IF I HAVE PYTHON INSTALLED AND NOTHING HAPPENS?
This occurs when the Python installation location is not in the system variables. System variables point to directories where the operating system we are using searches for programs that should be recognized automatically on the command line or by other software.
In Linux systems, the installation is rarely not found, but in Windows versions this happens much more easily, especially because it is possible, during Python installations, to request that it not add the PATH [path or directory] of the current installation to the system variables. Therefore, you will have to go to installed programs and look for any installation. If nothing is found, and you did not install via compilation from source, then Python is not installed.
