Overview of this book

This Learning Path shows you how to leverage the power of both native and third-party Python libraries for building robust and responsive applications. You will learn about profilers and reactive programming, concurrency and parallelism, as well as tools for making your apps quick and efficient. You will discover how to write code for parallel architectures using TensorFlow and Theano, and use a cluster of computers for large-scale computations using technologies such as Dask and PySpark. With the knowledge of how Python design patterns work, you will be able to clone objects, secure interfaces, dynamically choose algorithms, and accomplish much more in high performance computing. By the end of this Learning Path, you will have the skills and confidence to build engaging models that quickly offer efficient solutions to your problems. This Learning Path includes content from the following Packt products: • Python High Performance - Second Edition by Gabriele Lanaro • Mastering Concurrency in Python by Quan Nguyen • Mastering Python Design Patterns by Sakis Kasampalis

The requests module


The requests module allows its users to make and send HTTP request methods. In the applications that we will be considering, it is mainly used to make contact with the server of the web pages we want to extract data from and obtain the response for the server.

Note

According to the official documentation of the module, the use of Python 3 is highly recommended over Python 2 for requests.

To install the module on your computer, run the following:

pip install requests

You should use this code if you are using pip as your package manager. If, however, you are using Anaconda instead, simply use the following:

conda install requests

These commands should install requests and any other required dependencies (idna, certifi, urllib3, and so on) for you if your system does not have those already. After this, run import requests in a Python interpreter to confirm that the module has been installed successfully.

Making a request in Python

Let's look at an example usage of the module. If...
