Python for Everybody (py4e.com)

Explore the nature of programming and how programming a computer is different than using a computer.

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 how writing programs is just another form of communication. Instead of communicating with another person, we are communicating our ideas to a computer.

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.
