In this lesson you’ll get a general overview about the requests library. Furthermore, it reveals you how to install requests on your machine using pip and how to import it. In fact it’s as easy as:

Shell
      
$ pip install requests

After installing requests you’re able to import into your project via:

Python

import requests

00:00 Hi, this is Chris Bailey. I’m going to be taking you through Python’s requests library. This is Section 1 of 3, and it will be getting started with requests, introducing the GET request, and processing responses—talking about status codes, and content, and headers.

00:15 A couple of quick details about requests. The subtitle is HTTP for Humans™. It was created by Kenneth Reitz, and this is a link to the docs.

00:25 So, why learn about requests? It’s the defacto standard for making HTTP requests in Python. It’s a beautifully simple API, it abstracts the complicated parts of HTTP, and it focuses on interaction with services. So, what do you need to know for this tutorial?

00:40 Just a basic knowledge of HTTP. You can get that from a link that’s in the article, or I’m repeating it right here, from W3Schools. All right, let’s get started. The first step is to install requests. To do that we’re going to use pip, and it’s simply pip install requests.

00:57 As you can see here, I’ve already installed it on this machine. Let’s step into a REPL. The one I’m using is called bpython.

01:05 Let’s make sure it worked. We’ll go ahead and import it.

01:10 All right, looks like it’s successful. Great! Let’s get started with the GET request.

Hi Chris, thanks for the tutorial :-) Getting to know bpython was already worth so much! I didn’t know it so far but it already helped me today to get an effortless look into some module functions!

Thanks so much Dominic! I’m really getting mileage out of bptyhon, its fantastic for inspecting elements.

Evan E on May 1, 2019

Yeah, big ups on bpython. I’ve been using bpython since Dan Bader showed it back when he use to make YouTube vids;)

Hi @ll, what’s the best way to install bpython? I’m getting error on homebrew and pip3…

emalfiza on Jan. 24, 2020

Hey Christ, why the bpython installation doesnt work? I tried in my Mac terminal and even in PyCharm terminal?

Chris Bailey RP Team on Jan. 24, 2020

Hi @emalfiza. I’m sorry you are having trouble with bpython. What type of error are you getting? What version of Python do you have, is it a version from Python.org or a different distribution, and which version of macOS? I have had lots of issues of late installing libraries/packages and python itself, as I had to start over with a new drive (SSD) in my Mac. Two of the problems I had involved for one the inability to compile the version of the package on my machine, and the other had to do with not having certificates installed. For the compiling I needed to update Xcode libraries, which the error I got in the terminal walked me through. The other issue with certificates had to do with the version of Python not automatically installing those certificates, and needing to go into the folder where Python is installed and click to run, Install Certificates.command.

In general the best method of installing is using python3 -m pip install bpython, but it would help to know what errors you are getting.

emalfiza on Jan. 24, 2020

Hey @ChristBailey grateful of your reply to the issue.

I have the Python3 3.8.0 version install in my MacOS Catalina version 10.15.2 and I have downloaded python3 from python.org.

I tried the commands that you have used in the HTTP requests module plus the python3 -m pip install bpython and as will as python3 -m pip3 install bpython, but no joy.

The errors that I get is really verbose:

 ERROR: Command errored out with exit status 1:

By the way I really loved and enjoyed your tutorials.

Chris Bailey RP Team on Jan. 24, 2020

Hi @emalfiza, It looks like you are having a gcc compiler issue, but I’m not positive. The section (error:invalid active developer path(....CommandLineTools)) is referring to it being unable to find those tools I think. If you recently upgraded to Catalina, it can sometimes remove the tools, or makes other changes so that they don’t work. There is a terminal command to re-install them. xcode-select --install Here is a thread with more about it I found. I hope this helps.
