Lesson Goals

This lesson shows you how to download and install Python modules. Thereare many ways to install external modules, but for the purposes of thislesson, we’re going to use a program called pip, easily installable on mac/linux and windows. As of Python 2.7.9 and newer, pip is installed by default. This tutorial will be helpful for anyone using older versions of Python (which are still quite common).

New installations of Python usually come with pip out of the box and there are a few ways to do this on Mac. Installing Python With Homebrew: brew install python. Remember, you may have to use py instead of python 2. Run the following commands in a command prompt window: python -m pip install pyaudio python -m pip install numpy Installing PyAudio on Linux If you have a Linux machine you should be able to just follow the mac instructions but with your own package manager. The main advantage of that solution is that it install pip for the python version that has been used to run get-pip.py, which means that if you use the default OS X installation of python to run get-pip.py you will install pip for the python install from the system.

Introducing Modules

One of the great things about using Python is the number of fantasticcode libraries that are widely and easily available that can save you alot of coding, or simply make a particular task (like creating a CSVfile, or scraping a webpage) much easier. When Googling for solutions toproblems, you’ll often find sample code that uses code libraries youhaven’t heard about before. Don’t let these scare you away! Once theselibraries are installed on your computer, you can use them by importingthem at the beginning of your code; you can import as many libraries asyou’d like, such as

For new Python users, it can be a bit intimidating to download andinstall external modules for the first time. There are many ways ofdoing it (thus adding to the confusion); this lesson introduces one ofthe easiest and most common ways of installing python modules.

The goal here is to install software on your computer that canautomatically download and install Python modules for us. We’re going touse a program called pip.

Note: As of Python 3.4, pip will be included in the regular install.There are many reasons why you might not have this version yet, and incase you don’t, these instructions should help.

Install

Mac and Linux instructions

As per the pip documentation, we can download a python script to installpip for us. Using a Mac or Linux, we can install pip via the commandline by using the curl command, which downloads the pip installationperl script.

once you’ve downloaded the get-pip.py file, you need to execute it withthe python interpreter. However, if you try to execute the script withpython like

the script will most likely fail because it won’t have permissions toupdate certain directories on your filesystem that are by default set sothat random scripts cannot change important files and give you viruses.In this case—and in all cases where you need to allow a script that youtrust to write to your system folders—you can use the sudo command(short for “Super User DO”) in front of the python command, like

Windows Instructions

As with the above platforms, the easiest way to install pip is throughthe use of a python program called get-pip.py, which you can downloadhere. When you open this link, you might be scared of the massivejumble of code that awaits you. Please don’t be. Simply use your browserto save this page under its default name, which is get-pip.py. It mightbe a good idea to save this file in your python directory, so you knowwhere to find it.

Once you have saved this file, you need to run it, which can be done intwo ways. If you prefer using your python interpreter, just right-clickon the file get-pip.py and choose “open with” and then choose whateverpython interpreter you care to use.

If you prefer to install pip using the windows command line, navigate towhatever directory you’ve placed python and get-pip.py. For thisexample, we’ll assume this directory is python27, so we’ll use thecommand C:>cd python27. Once you are in this directory, to install pip run thecommand

Installing Python Modules

Now that you have pip, it is easy to install python modules since itdoes all the work for you. When you find a module that you want to use,usually the documentation or installation instructions will include thenecessary pip command, such as

Remember, for the same reasons explained above (on Mac or Linux systems, but not Windows), you might need to run pip with sudo, like

Sometimes, especially on Windows, you may find it helpful to use the -m flag (to help python find the pip module), like

Happy installing!

Python Mac Pip Installer

PyQt is often not installed by default. The PyQt module can be used to create desktop applications with Python. In this article you’ll learn how to install the PyQt module.

The steps to install pip3 are simple and easy to follow. Once you have python 3, use the following command to install pip3: sudo apt-get update sudo apt install python3-pip. Python3 get-pip.py. When you run this command, it installs the applications used to build python modules. Download Mac OS X 64-bit/32-bit x86-64/i386 Installer; Python 2.6.9 - Oct. No files for this release. Python 3.3.2 - May 15, 2013.

Desktop applications made with PyQt are cross platform, they will work on Microsoft Windows, Apple Mac OS X and Linux computers (including Raspberry Pi).

$ sudo apt-get update $ sudo apt-get install python3.8 python3-pip Once the installation is complete, you can run Python 3.8 with the python3.8 command and pip with the pip3 command. Linux Mint and Ubuntu 17 and below: Python 3.8 isn’t in the Universe repository, so you need to get it from a Personal Package Archive (PPA). PyQt is often not installed by default. The PyQt module can be used to create desktop applications with Python. In this article you’ll learn how to install the PyQt module. Desktop applications made with PyQt are cross platform, they will work on Microsoft Windows, Apple Mac OS X and Linux computers (including Raspberry Pi). Doing it Right¶. Let’s install a real version of Python. Before installing Python, you’ll need to install GCC. GCC can be obtained by downloading Xcode, the smaller Command Line Tools (must have an Apple account) or the even smaller OSX-GCC-Installer package.

How to install PyQt5 on Windows?

To install PyQt on Windows there are a few steps you need to take.
First use the installer from the qt-project website, from qt to install PyQt.

Next you want to install a Python version 3.3 or newer. Check the box to add all of the PyQt5 extras. It’s not necessary to compile everything from source, you can install all the required packages with the installer.

On Python >= 3.6, you can also try this command:

It should work without problems.

How to install PyQt5 on Mac OS X?

On Apple Mac OS X installation is a bit simpler. The first step to take is to install the Mac OS X binary. This installs the PyQt GUI library.

But to use it from Python, you also need Python module. This is where the tool brew comes in.
You can use brew to install pyqt (in the terminal):

How to install PyQt5 on Linux?

Python is often installed by default on Linux (in nearly all of the distributions including Ubuntu). But you want to make sure to use Python 3, because of all the features and ease of use. You can verify that you have the newest Python version with the command:

On Ubuntu Linux they sometimes include two versions of python, python3 and python. In that case use Python 3.

Once you have Python ready, the next step is to install PyQt.

This isn’t hard to do if you have some Linux experience. You can install PyQt your software package manager. Which package manager to use depends on which Linux distribution you are using.

On Ubuntu Linux / Debian Linux you can use the command:

Mac Pip Install Python 3.7

For CentOS 7 use the command:

For RPM-based systems (Redhat-based)

If you are new to Python PyQt, then I highly recommend this book.

Mac OS X comes with Python 2.7 out of the box.

You do not need to install or configure anything else to use Python 2. Theseinstructions document the installation of Python 3.

The version of Python that ships with OS X is great for learning, but it’s notgood for development. The version shipped with OS X may be out of date from theofficial current Python release,which is considered the stable production version.

Doing it Right¶

Let’s install a real version of Python.

Before installing Python, you’ll need to install GCC. GCC can be obtainedby downloading Xcode, the smallerCommand Line Tools (must have anApple account) or the even smaller OSX-GCC-Installerpackage.

Note

If you already have Xcode installed, do not install OSX-GCC-Installer.In combination, the software can cause issues that are difficult todiagnose.

Note

If you perform a fresh install of Xcode, you will also need to add thecommandline tools by running xcode-select--install on the terminal.

Pip

While OS X comes with a large number of Unix utilities, those familiar withLinux systems will notice one key component missing: a package manager.Homebrew fills this void.

To install Homebrew, open Terminal oryour favorite OS X terminal emulator and run

The script will explain what changes it will make and prompt you before theinstallation begins.Once you’ve installed Homebrew, insert the Homebrew directory at the topof your PATH environment variable. You can do this by adding the followingline at the bottom of your ~/.profile file

If you have OS X 10.12 (Sierra) or older use this line instead

Now, we can install Python 3:

This will take a minute or two.

Pip¶

Homebrew installs pip pointing to the Homebrew’d Python 3 for you.

Working with Python 3¶

At this point, you have the system Python 2.7 available, potentially theHomebrew version of Python 2 installed, and the Homebrewversion of Python 3 as well.

will launch the Homebrew-installed Python 3 interpreter.

will launch the Homebrew-installed Python 2 interpreter (if any).

will launch the Homebrew-installed Python 3 interpreter.

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.

Pipenv & Virtual Environments¶

The next step is to install Pipenv, so you can install dependencies and manage virtual environments.

Pip Install Virtualenv Python3 Mac

A Virtual Environment is a tool to keep the dependencies required by different projectsin separate places, by creating virtual Python environments for them. It solves the“Project X depends on version 1.x but, Project Y needs 4.x” dilemma, and keepsyour global site-packages directory clean and manageable.
