Python is an interpreted, high-level, general-purpose programming language. It has variety of use cases. You can use it for automating certain tasks and do a lot more with it. Here we will see how to install python in your computer. By the way, we are going to use Python 3 not Python 2, so wherever I mention python that will mean Python 3, if not explicitly mentioned something else.

Check whether you have python in your system or not, by typing
python in terminal or command prompt. If you see something like this, then you don't have python installed.
> python 'python' is not recognized as an internal or external command, operable program or batch file.
Head over to Python Official Website and go to the downloads section. Choose the latest stable python 3 version, download the executable file and install it. Do not forget to add python to your path, so that you can use python from terminal.
Make sure that the box, indicated using red arrow sign, is checked.
You should already have python in your system. You can verify it by typing
python3 in terminal and then hitting enter. You should see something like this
$ python3 Python 3.6.9 (default, Nov 7 2019, 10:44:02) [GCC 8.3.0] on linux Type "help", "copyright", "credits" or "license" for more information. >>>
I personally use Anaconda Python. It comes with its own package manager, called
conda and it has has lots of packages pre-installed, so you don't have to install them separately. Head over to their download page and download the version suitable for you system.
Check out their official installation guides.
After the installation is successful, open a new terminal or command prompt and type
python. You should see something like this
> python Python 3.7.4 (default, Aug 9 2019, 18:34:13) [MSC v.1915 64 bit (AMD64)] :: Anaconda, Inc. on win32 Type "help", "copyright", "credits" or "license" for more information. >>>
In the python shell after the
>>> sign type
print("Hello World") and hit enter. You will see output like this
> python Python 3.7.4 (default, Aug 9 2019, 18:34:13) [MSC v.1915 64 bit (AMD64)] :: Anaconda, Inc. on win32 Type "help", "copyright", "credits" or "license" for more information. >>> print("Hello World") Hello World >>>
