RxPY – Environment Setup

In this chapter, we’ll focus on installing RxPy. To get started with RxPY, we need to first install Python. Therefore, we will do the following:

• Install Python
• Install RxPy

Install Python

Go to the official Python website: href=”https://www.python.org/downloads/”>https://www.python.org/downloads/. As shown below, click the latest version available for Windows, Linux/Unix, and Mac OS. Download Python based on your 64-bit or 32-bit operating system.

After the download is complete, click the .exe file and follow the steps to install Python on your system.

The Python package manager, pip, will also be installed by default in the above installation. To enable it globally on your system, simply add the Python location to your PATH variable.

Installing RxPY

Now that Python is installed, we will install RxPy.

Once Python is installed, the Python package manager, pip, will also be installed. Here is the command to check the pip version –

E:pyrx>pip --version
pip 19.1.1 from c:usersxxxxappdatalocalprogramspythonpython37libsite-
packagespip (Python 3.7)
