Python tools to interact with the user

In the previous section, we saw how to get information from the user on the command line, but what do we do when we need a more dynamic form of interaction? So, let's take a look at some of Python's tools for sending information to the user and requesting information from the user.

Python's built-in functions - print and input

The fundamentals of interactivity are simple. We need to be able to tell the user things and we need the user to be able to tell us things. In service of those two goals, Python provides two built-in functions. These are print and input.

Create a simple.py file with the following code:

The print function takes any number of Python objects as parameters and prints them on the screen. The input function takes a string prompt as its parameter, prints it out, then reads text until the user hits Enter, and returns what the user typed as a string.

Run the following command to see how the print and input functions work:

python3 simple.py
