Python Primer

Greg Trzeciak introduces Python Primer and explains how it prepares you for the Pragmatic Works Python Labs. He covers what the course includes and how each module builds toward the skills you’ll use in the labs. By the end of this module, you’ll know what to expect from the course and how it fits into your Python learning path.

This module covers functions, one of the core building blocks of Python. You’ll learn what a function is, how to call one, and how to pass it a value. You’ll then use print() to display output on the screen, the first function you’ll use in nearly every Python Lab. By the end, you’ll be able to write and run simple lines of code that produce visible results.

Building on the previous module, Greg shows how to nest print() with other expressions and function calls to produce more complex output. You’ll see how Python evaluates the inner parts of a statement before printing the result, which is a key idea for reading and writing code in the labs. This module builds your confidence combining pieces of Python into a single working statement.

In the final module, you’ll learn how if statements let your code make decisions by running different instructions based on whether a condition is true. You’ll see how to write a basic condition and control what your program does in response. Greg then recaps the course and points you to the next step: putting these fundamentals to work in the Python Labs.
