1.1 Why Program

2016-10-0112:30

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

1.2 Hardware Architecture

2016-10-0112:15

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.

1.3 Python as a Language

2016-10-0107:48

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?

2016-10-0112:45

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

2016-09-3009:41

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

2016-09-3019:53

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

2016-09-3011:061

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 question).

3.2 More Conditional Statements

2016-09-3013:51

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.

4.1 Using Pre-Defined Functions

2016-09-3010:29

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

2016-09-3012:35

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

2016-09-3009:58

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.

5.2 Definite Loops

2016-09-3006:51

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

5.3 Patterns for Making Loops

2016-09-3008:43

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.
