Python for Everybody (py4e.com)

1.1 Why Program

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

1.2 Hardware Architecture

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 w

1.3 Python as a Language

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.

1.4 What do we Say to Python?

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.

2.1 Building Blocks of Python

We look at Python's reserved words, how we name and use variables, why we choose meaningful (mnemonic) variable names and how assignment statements function.

2.2 Expressions

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

3.1 If-Then-Else

The most basic conditional structure is the if statement where we either execute or skip a segment of code based on the results of a logical expression (i.e. asking a que

3.2 More Conditional Statements

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 b

4.1 Using Pre-Defined Functions

We look at how code flows into and out of functions as well has how we pass information into functions and get results returned to us.

4.2 Building our Own Functions

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.

5.1 The Basics of Loops

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 &apos

5.2 Definite Loops

We learn how to use the 'for' statement in Python to loop through a set of data.

5.3 Patterns for Making Loops

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 ave
