Once you are up and running with homebrew, installing Python on MacOS is as easy as: $ brew install python Official installer. Alternatively, you can download an installer from the Python download website. The downside to this approach is that you won’t get automatic updates. Install Python on Linux. There are several ways to install Python. Python has been installed as $(brew -prefix)/bin/python3 Unversioned symlinks `python`, `python-config`, `pip` etc. Pointing to `python3`, `python3-config`, `pip3` etc., respectively, have been installed into. Install Ta-Lib Across Platforms Using Anaconda Prompt. Anaconda is an open-source Python distribution platform that helps individuals, as well as commercial enterprises, implement their Python codes easily. It also makes life easier when it comes to installing various Python libraries. Install latest Python3 with brew install python Once Python is installed, you should be able to open your Terminal application, type python3, hit ENTER, and see a Python 3.X.X prompt opened. Type quit to exit it.

In this chapter, you learn how to install Python on MacOS, Windows, and Linux. We will look at multiple installation methods per platform and discuss what I think is the best option to choose from.

Most of the time, it’s not advisable to use the official installer from the python.org website. Instead, it’s better to go for the version packaged by your operating system. The advantage of OS supplied version, is that you’ll get automatic updates.

Install Python on Windows

There are three methods you can choose from on Windows.

Using The Microsoft Store

Microsoft hosts a community release of Python 3 in the Microsoft Store. This is the recommended way to install Python on Windows because it handles updates automatically and can be uninstalled easily too.

To use this method:

  • Pick the newest version and install it

With the official installer

You can download a Python installer from the official Python download website too. This method does not give you automatic updates, and I would recommend it only if you don’t have access to the Microsoft store.

Inside WSL

If you’re familiar with Windows Subsystem For Linux, you may want to consider that option too. It’s what I use myself, and I’m truly loving it. It offers me the advantages that Windows has to offer (mainly great hardware support), while still enjoying Linux which is, in my opinion, the best platform for Python development.

To install in WSL, you’ll first need to install WSL itself. Go for WSL2 if you can. It’s much better. After that, simply follow the Linux installation instructions below!

Installation on MacOS

On most versions of MacOS before Catalina, a distribution of Python is already included. Unfortunately, it’s almost certainly an old version, Python 2.7. Luckily, there are two ways to install Python 3 on a Mac with ease.

Homebrew

First and foremost, I recommend looking into Homebrew. It allows you to install almost anything easily. The added benefit is that it’s also easy to upgrade to newer versions later on.

Once you are up and running with homebrew, installing Python on MacOS is as easy as:

Official installer

Alternatively, you can download an installer from the Python download website. The downside to this approach is that you won’t get automatic updates.

Install Python on Linux

There are several ways to install Python on Linux, that is, if you need to install it at all!

Check what’s installed first

Most Linux distributions include Python. Many will include both Python 2 and Python 3.

If you enter python --version on the command line, you’ll see the version number. It’s probably version 2.7:

You don’t want Python 2, but some OS’es still ship with it, unfortunately.

Now try python3 --version. If you get a “command not found,” you need to install Python 3. If your output looks similar to this, you’re in luck:

Using a package manager

Depending on the distribution of Linux you are running, you can install Python with the default package manager: Yum, APT, etcetera. You’ll need to find out for your specific Linux distribution which package manager is used and how to use it.

If you’re on Ubuntu, Linux Mint, or Debian, you can install using apt:

Homebrew

Another interesting option for Linux is using Homebrew. That’s right, the package manager for Macs also works on Linux.

Brew Install Python Version

The major advantages of using Homebrew:

  • You’ll get the latest version of Python, instead of the version your OS shipped with
  • You don’t need root access to your system. All the software installed with Homebrew is installed in your home directory

I find myself using Homebrew more and more while working under Linux — give it a try!

Python in your browser

If you don’t feel like installing Python, or you are unable to install it for whatever reason, I’ll offer an alternative too: you can use Python right from your browser; no installation necessary!

Python is very popular programming and scripting language. It provides useful modules and libraries but also there is a lot of popular 3rd party library. Pip is the command and tools used to install, update and remove 3rd party packages. In this tutorial, we will learn how to install pip and some useful information.

Check and Display Python Version

Before installing the pip we have to be sure that Python is installed. Also, the version of the Python is important because pip will be installed according to this Python version.

We can see that both PYthon2 and PYthon3 is installed. So we can use installation commands for both Python2 and Python3. The python2 version is Python2.7.16 and Python3 version is Python3.6.8 .

Install Pip with easy_install On MacOS

easy_install is a Python module bundled with setuptools which gives us the ability to download, build, install, and manage Python packages. Before pip easy_install was the standard package manager for the Python. We can install pip with the easy_install command like below.

If the pip is already installed we can also upgrade the existing pip installation with the easy_install like below. We will use the pip command because it installed already and provide the --upgrade option with the package name which is also pip.

Install Pip with get-pip.py On MacOS

get-pip.py is another way to install pip in MacOS. get-pip.py is a Python script that will simply download and install the Pip package for Python. First, we will download the get-pip.py script with the curl command. We will provide the URL with the -o option where we will set the name of the downloaded get-pip.py file name.

Brew install python-dev

AND then we will call the get-pip.py with the Python interpreter. This will run the get-pip.py file Python codes which will simply install the pip for the macOS or OS X.

Brew Install Python 2.7

Install Pip with brew On MacOS

Homebrew is the package management tool for the macOS. We can use Homebrew in order to install Python and pip. pip is provided with the python package. We will use brew command with the install command like below.

If there are problems related to the pip usage we may need to relink the python with the following command.

Check and Display Pip Version

Brew Install Python Specific Version

We can check installed pip version with the -V or --version option like below.

Brew Install Python 3

We can see that Python2 pip version is pip 9.0.1 and Python3 pip version is pip 9.0.1 . They are the same version for both Python2 and Python3. This is because to prevent version conflicts and synchronize the feature development of the pip command for both Python versions.
