Python 3 mac command line

Homebrew fills this void. The script will explain what changes it will make and prompt you before the installation begins. At this point, you have the system Python 2. If the Homebrew version of Python 2 is installed then pip2 will point to Python 2. If the Homebrew version of Python 3 is installed then pip will point to Python 3. The rest of the guide will assume that python references Python 3. The next step is to install Pipenv, so you can install dependencies and manage virtual environments. A Virtual Environment is a tool to keep the dependencies required by different projects in separate places, by creating virtual Python environments for them.

For example, you can work on a project which requires Django 1.

So, onward! This page is a remixed version of another guide , which is available under the same license. This opinionated guide exists to provide both novice and expert Python developers a best practice handbook to the installation, configuration, and usage of Python on a daily basis.

Easy to set up, and written in a relatively straightforward style with immediate feedback on errors, Python is a great choice for beginners and experienced developers alike. Python 3 is the most current version of the language and is considered to be the future of Python. This tutorial will guide you through installing Python 3 on your local macOS machine and setting up a programming environment via the command line.

The command line, also known as a shell, can help you modify and automate many of the tasks you do on a computer every day, and is an essential tool for software developers. The macOS Terminal is an application you can use to access the command line interface.

Like any other application, you can find it by going into Finder, navigating to the Applications folder, and then into the Utilities folder. From here, double-click the Terminal like any other application to open it up.

Alternatively, you can use Spotlight by holding down the command and spacebar keys to find Terminal by typing it out in the box that appears. There are many more Terminal commands to learn that can enable you to do more powerful things.

Xcode is an integrated development environment IDE that is comprised of software development tools for macOS. You may have Xcode installed already. To check, in your Terminal window, type:. If you received an error, then in your web browser install Xcode from the App Store and accept the default options. Once Xcode is installed, return to your Terminal window. At this point, Xcode and its Command Line Tools app are fully installed, and we are ready to install the package manager Homebrew.

While the OS X Terminal has a lot of the functionality of Linux Terminals and other Unix systems, it does not ship with a good package manager. A package manager is a collection of software tools that work to automate installation processes that include initial software installation, upgrading and configuring of software, and removing software as needed.

They keep installations in a central location and can maintain all software packages on the system in formats that are commonly used. Homebrew provides OS X with a free and open source software package managing system that simplifies the installation of software on OS X.

The curl command pulls a script from the specified URL. This script will explain what it will do and then pauses the process to prompt you to confirm. This provides you with a lot of feedback on what the script is going to be doing to your system and gives you the opportunity to verify the process. To save your changes, hold down the control key and the letter o , and when prompted press the return key.

Now you can exit nano by holding the control key and the letter x. Once you have done this, the changes you have made to the PATH environment variable will be effective. Otherwise, you may get a warning to run another command such as brew update to ensure that your installation of Homebrew is up to date. The Terminal window will give you feedback regarding the installation process of Python 3, it may take a few minutes before installation is complete.

Python 3.x or Python 2.x

Along with Python 3, Homebrew will install pip , setuptools and wheel. A tool for use with Python, we will use pip to install and manage programming packages we may want to use in our development projects. You can install Python packages by typing:. So if you would like to install NumPy, you can do so with the command pip3 install numpy. This will output the specific version of Python that is currently installed, which will by default be the most up-to-date stable version of Python 3 that is available.

Now that we have Xcode, Homebrew, and Python installed, we can go on to create our programming environment. Setting up a programming environment provides us with greater control over our Python projects and over how different versions of packages are handled.

This is especially important when working with third-party packages. You can set up as many Python programming environments as you would like. Each environment is basically a directory or folder in your computer that has a few scripts in it to make it act as an environment. Choose which directory you would like to put your Python programming environments in, or create a new directory with mkdir , as in:.

Once you are in the directory where you would like the environments to live, you can create an environment by running the following command:.
