Python Installation and Setup Guide

To get started working with Python 3, first of all, You will need to have access to the Python interpreter. There are
numerous ways to accomplish this:

Watch this Python Installation in Windows 10:

You can directly obtain it from the Python Software Foundation Youbsite at Python.org.
In operating systems like Linux, there will be a package manager which can be run to install Python.
On MacOS, to install Python 3, first You have to install a package manager called Homebrew. This will be discussed later
in the relevant section of this tutorial.
On mobile operating systems like Android and iOS, You can install Python apps which provide an environment for
Python programming.

Even there are so many Youbsit es that allow us to access a Python interpreter online without any installation on
your system.

Install Python on Windows

For Windows operating system, the installation process is as follows:

To install Python, firstly You need to go to the Download Python page from its official site python.org/download and
click on the latest version

Once the Python distribution download is completed, then double-click on the executable downloaded software, and
then click on Run

Now, once the installation set up starts, You need to follow the below-mentioned installation steps:

Step 1: A pop-up window, Python Version 3.7.0 (32-bit) Setup, will appear. Here, You need to ensure that You have checked
the checkboxes for ‘Install launcher for all users (recommended)’ and for ‘Add Python 3.7 to PATH’ at the bottom

Step 2: Now, a User Account Control pop-up window will appear, posing the question, ‘Do you want to allow the following
program to make changes to this computer?’ Click on Yes

Step 3: Now, a new Python 3.7.0 (32-bit) Setup pop-up window will appear with a ‘Setup Progress’ message and a progress
bar. During the installation, it will show us various components it is installing, and it will move the progress bar toward
completion. Soon, a new Python 3.7.0 (32-bit) Setup pop-up window will appear with a ‘Setup was successful’ message

Step 4: Once the installation is done, click on the Close button. And now, Python is successfully installed

Step 5: Now, You will try to verify the installation

Navigate to the directory:

C:\Users\AppData\Local\Programs\Python\Python37-32

or to whatever directory Python was installed (see Step 3 of the installation process)
Double-click on the icon/file python.exe

The following pop-up window will appear.

This pop-up window will be with the title:

C:\Users\AppData\Local\Programs\Python\Python37-32\python.exe
and inside the window, on the first line, You will get a text ‘Python 3.7.0…’. From here, You can notice that it also says ‘32 bit’.

Inside the window, at the bottom left, the prompt, ‘>>>’: type exit() to this prompt and press Enter to terminate Python.

Now, You should keep the file python-3.7.0.exe somewhere on our computer in case You need to reinstall Python.

To write a Python script file, You can use any text editing software. For that, You just have to save it with the .py extension.
But, using a Python IDE can make developers’ life a lot easier. IDE is a software that provides useful features like hinting
code, highlighting and checking syntax, file explorers, etc. to programmers for application development.

Some of the popular free Python IDEs are PyCharm, Spyder, Rodeo, and Jupyter Notebook. Jupyter Notebook is one of the
best among them.

Jupyter Notebook is a You application based on a server-client structure that allows us to create and manipulate notebook
documents—or just ‘notebooks.’

It provides us with an easy-to-use, interactive Data Science environment across many programming languages that doesn’t
only work as an IDE but also as a presentation or educational tool. This tool is perfect for those who are just starting out
with Data Science!

How to Install Python in Linux

Okay, so How to Install Python? Let’s talk about the installation of Python on Linux Machine.

Step 1: First, You have to navigate to the Python download site with our browser. Here, You will see different operating
systems to choose from; select Linux/UNIX

Step 2: Now, You will be navigated to Python Source Releases. Here, click on the appropriate link for our version of Linux:

Python 3.7.2 compressed source tarball (any version of Linux)

Python 3.7.2 gzipped source tarball (better compression and faster download)

Step 4: Now, double-click on the downloaded file. The Archive Manager window opens. After the files are extracted, You will
see the Python 3.3.4 folder in the Archive Manager window. Again, double-click on the Python 3.3.4 folder. Here, the Archive
Manager extracts the files to the Python 3.3.4 subfolder of our home folder

Step 5: Now, open a copy of Terminal. Here, if You have never built any software on our system before, then You must
install build-essentials, like SQLite and bzip2, otherwise our Python installation will fail. And, if You have already installed
them, You can skip the below steps and move to Step 9 to begin working with Python immediately

Step 6: Now, type  sudo apt-get install build-essential  and press Enter. Here, Linux installs the Build Essential support
required to build packages

Step 8: Now, type sudo apt-get install libbz2-dev and press Enter. Here, Linux installs the bzip2 support required by Python
for archive manipulation
Step 9: Type CD Python 3.3.4 in the Terminal window and press Enter. Here, the terminal changes directories to the Python
3.3.4 folder on our system.

Step 10: Type ./configure and press Enter. Here, the script begins by checking the system build type and then performs a
series of tasks based on the system You’re using. This process can require few minutes because there is a large list of items
to check.

Step 11: then type make and press Enter. Here, Linux executes the make script to create the Python application software.
The make process can require up to 1 minute—it depends on the processing speed of our system.

Step 12: Now, type  sudo make altinstall  and press Enter. Here, the system may ask us for our administrator password.
Type  the password  and press Enter. At this point, a number of tasks take place as the system installs Python on our
system.

Now, our Python is up and running. You can execute our first program!

How to Install Python in Ubuntu

Python comes pre-installed in all the versions of Ubuntu that come after Ubuntu 14.04 since the Linux distributions
themselves use Python extensively for their own purposes.

You can type the following command in Ubuntu terminal to check if the latest version of Python is already installed in
your Ubuntu system or not:

python3 -v

or

python3 --version

To check if you have several versions installed on your Ubuntu, type the following command in your Ubuntu terminal:

apt list --installed | grep python

To access Python 2 in Ubuntu, just type the following command in the Ubuntu terminal:

python

To access Python 3 in Ubuntu, type the following command in Ubuntu terminal:

python3

If by any chance, your Ubuntu system does not have Python installed, or you are using older version of Ubuntu, then
you can use the command mentioned below to install it.

sudo apt-get install python3

This command will install the latest version of Python in your Ubuntu system. You can check the version using the
command mentioned above.

In case you have Python already installed but it’s not the latest version, then you can upgrade you Python package
using the command mentioned below.

sudo apt-get upgrade python3

to install Python 3 on our local MacOS machine, and You will also set up a programming
environment via the command line. To do installation, You will need administrative access that is connected to the Internet.

To install Python on MacOS X, first, You have to install Xcode, then You have to install Homebrew, and then Python.
Install Xcode
You require Xcode to install Homebrew and Python. You can download Xcode from the App Store.

Installing Xcode from the App Store is a time-consuming process. After the lengthy download and install processes, You
have to open a terminal and type the following command to install Xcode Command Line tools, and in the next step You
will install Homebrew.

Homebrew is a package manager for OSX. You can use it to install specific versions of Python that coexist with, and prevent
the pollution of, the system Python.

Now, go to Install Homebrew

From here, follow the directions to install Homebrew. Once done, paste this line into a terminal:

/usr/bin/ruby -e “$(curl -fsSL https://abc.com/Homebrew/install/master/install)”

Now our Homebrew is installed, which is used to install Python. The OSX system will still use the built-in system Python, but
anything You do will use the newly installed Python

Install latest python 3:

brew install python

Install latest python 3.x

brew install python3
