5.1 The Basics of Loops Sep 30, 2016

Show notes

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 Sep 30, 2016

Show notes

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

5.3 Patterns for Making Loops Sep 30, 2016

Show notes

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.

5.4 Loop Techniques Sep 30, 2016

Show notes

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.

6.1 Storing Text Data in Strings Sep 30, 2016

Show notes

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.

6.2 String Operations Sep 30, 2016

Show notes

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

7.1 Reading Files Sep 30, 2016

Show notes

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.

7.2 Processing Data in Files Sep 30, 2016

Show notes

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.

8.1 Creating and Using Lists Sep 30, 2016

Show notes

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.

8.2 Manipulating Lists Sep 30, 2016

Show notes

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