1.1 Why Program

Python for Everybody (Audio/PY4E) ·

2016/10/01

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

en-US

12:15

1.2 Hardware Architecture

Python for Everybody (Audio/PY4E) ·

2016/10/01

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.

7:48

1.3 Python as a Language

Python for Everybody (Audio/PY4E) ·

2016/10/01

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.

en-US

12:45

1.4 What do we Say to Python?

Python for Everybody (Audio/PY4E) ·

2016/10/01

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.

en-US

9:40

2.1 Building Blocks of Python

Python for Everybody (Audio/PY4E) ·

2016/09/30

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.

en-US

19:52

2.2 Expressions

Python for Everybody (Audio/PY4E) ·

2016/09/30

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

en-US

13:29

3.1 If-Then-Else

Python for Everybody (Audio/PY4E) ·

2016/09/30

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).

en-US

13:51

3.2 More Conditional Statements

Python for Everybody (Audio/PY4E) ·

2016/09/30

In this lecture 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.

en-US

10:29

4.1 Using Pre-Defined Functions

Python for Everybody (Audio/PY4E) ·

2016/09/30

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.

en-US

12:34

4.2 Building our Own Functions

Python for Everybody (Audio/PY4E) ·

2016/09/30

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.

en-US

9:58

5.1 The Basics of Loops

Python for Everybody (Audio/PY4E) ·

2016/09/30

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.

en-US

6:51

5.2 Definite Loops

Python for Everybody (Audio/PY4E) ·

2016/09/30

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

en-US

8:43

5.3 Patterns for Making Loops

Python for Everybody (Audio/PY4E) ·

2016/09/30

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.

en-US

18:47

5.4 Loop Techniques

Python for Everybody (Audio/PY4E) ·

2016/09/30

We continue to look at how to construct loops including how to do something special the first time through the loop. We introduce the idea of 'None' which is a way to indicate that a variable is currently empty.

en-US

10:42

6.1 Storing Text Data in Strings

Python for Everybody (Audio/PY4E) ·

2016/09/30

We learn how to create string variables and extract portions of the data as well as write simple loops to read through the characters in a string.

en-US

18:44

6.2 String Operations

Python for Everybody (Audio/PY4E) ·

2016/09/30

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

en-US

7:54

7.1 Reading Files

Python for Everybody (Audio/PY4E) ·

2016/09/30

We look at how text and lines are represented in files, how we open a file and write a loop to read through all the lines in the file.

en-US

13:46

7.2 Processing Data in Files

Python for Everybody (Audio/PY4E) ·

2016/09/30

We look at patterns for reading and processing the data in files. We learn how to check for nonexistent files, and how we process each line within the file.

en-US

10:56

8.1 Creating and Using Lists

Python for Everybody (Audio/PY4E) ·

2016/09/30

We learn how to put data into lists, take data out of the list and write simple loops to examine the elements of a list.

en-US

9:36

8.2 Manipulating Lists

Python for Everybody (Audio/PY4E) ·

2016/09/30

We learn about list slicing, list searching, and using pre-defined functions with lists.
