For centos: yum install python-requests For Ubuntu: apt-get install python-requests. Use pip install requests (or pip3 install requests for python3) if you have pip installed and Pip.exe added to the Path Environment Variable. If pip is installed but not in your path you can use python -m pip install requests (or python3 -m pip install. Make a GET request to ‘python.org’, using Requests: Try async and get some sites at the same time: Grab a list of all links on the page, as–is (anchors excluded): Grab a list of all links on the page, in absolute form (anchors excluded): Select an element with a CSS Selector: Grab an element’s text contents. Install Tk for Python (Tkinter) on Linux/X11. Tkinter (and, since Python 3.1, ttk, which is the interface to the newer themed widgets) is included in the Python standard library. It relies on Tcl/Tk being installed on your system. Depending on how you install Python, this may not happen automatically. Installing Requests and Supported Versions. Requests is available on PyPI: $ python -m pip install requests Requests officially supports Python 2.7 & 3.6+. Supported Features & Best–Practices. Requests is ready for the demands of building robust and reliable HTTP–speaking applications, for the needs of today. Keep-Alive & Connection Pooling. Apple’s Mac OS comes with python 2.7 installed by default. Perhaps you may want to use python 3.x.x on your machine and also use pip for package management with python 3.x.x. The easiest way to achieve this is by: NOTE: This tutorial does not use Virtual Environments like virtualenv or pyenv to manage various python versions.

1. Installing python3

• Follow this link and download the latest python3OS X package
• Run the package and follow the steps to install python3 on your computer.
• Once the installation is done, on your Terminal, run

This will print out the version of python installed on your system. The output should be similar to:

You may verify the installation directory of python by runningthe following line on the Terminal.

The prompt should print the install path for python3. An example output is:

2. Install pip3:

• Securely download the get-pip.py file from this link
• From the directory where the file was downloaded to, run the following command in the Terminal

• Once the installation completes you should see the prompt print message similar to this
• Verify the installation of pip3 by running the following on the Terminal

This should return the install location of pip3.

• To install python3 packages using pip3, run

Remember to replace packageName with the appropriate package name for your case.

Happy Pythoning!

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).

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.

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
