Python for Everybody (py4e.com)

In this lecture we learn abut how the computer processes and stores programs. We learn about the CPU, Memory, Storage and Input / Output devices are brought together to write a program.

We look at the basics of the Python language and how we write code in Python to communicate sequential steps, conditional steps and repeated steps.

Code Walkthrough: Hello World

We look at how we use various numerical and string operations to compute new information and store the new values in variables.

Code Walkthrough: Exercise 2.3

In this video we look at multi-branch if statements and the try-except concept where we can indicate a group of statements to be executed if something goes wrong with a block of statements.

Code Walkthrough: Exercise 3.2

We look at how to build our own functions using parameters and arguments as well as how we return results to the code that is calling our functions.

We look at how we construct a loop so that it runs as long as we want it to run. We learn about iteration variables and exiting loops with the 'break' and 'continue' statements.

Loops have a beginning, middle, and end. We look ant how we construct a loop to look at a list of items one at a time so we can compute an overall maximum, minimum or average.

Worked Exercise: Exercise 5.1

We learn how to extract substrings using slicing, and use the string library to perform common data extraction operations with strings.
