Configuring our environment

We are finally here and building our first web application from scratch! From scratch means working from the beginning, even before an empty Python file. The approach is easy – we start by sitting and coding together. Let’s start by creating our virtual environment, which is dedicated exclusively to this new app we will develop:

1. As we’ve already learned in previous chapters, we must fire up our Terminator terminal and create an empty directory named web_app1 with the following instructions:

   mkdir web_app1

2. Then, we must enter the following instruction in the terminal:

   cd web_app1

3. Finally, we must write the following:

   pipenv shell

The last instruction, as we saw previously and already know, will create the virtual environment with pipenv, as shown in Figure 4.1:

Since it will help us a lot in managing code and Streamlit’s execution...
