+Here are the videos I've completed so far:
+
+* [Chapter 1: How to write and test a Python program](https://www.youtube.com/playlist?list=PLhOuww6rJJNP7UvTeF6_tQ1xcubAs9hvO): How to create a Python program, understanding comments and the shebang, how to make a program executable and install into your $PATH, how to write a main() function, add docstrings, format your code, and run tests.
+
+* [Chapter 2: Crow's Nest](https://www.youtube.com/playlist?list=PLhOuww6rJJNPBqIwfD-0RedqsitBliLhT): How to write a Python program that accepts a single, positional argument and creates a newly formatted output string.
+
+* [Chapter 3: Picnic](https://www.youtube.com/playlist?list=PLhOuww6rJJNMuQohHrNxRjhFTR9UlUOIa): Writing a Python program that accepts multiple string arguments and formats the results depending on the number of items.
+
+* [Chapter 4: Jump The Five](https://www.youtube.com/playlist?list=PLhOuww6rJJNNd1Mbu3h6SGfhD-8rRxLTp): Writing a Python program to encode the numerals in a given text using an algorithm called "Jump The Five." Use of a dictionary as a lookup table, characters not in the dictionary remain unchanged. Introduction to encoding/decoding text, basic idea of encryption.
+
+* [Chapter 5: Howler](https://www.youtube.com/playlist?list=PLhOuww6rJJNNzo5zqtx0388myQkUKyrQz): Writing a Python program that can process input text either from the command line or from a file.The output prints either to STDOUT or to a file.  Learning about "os.path.isfile", how to "open" a file handle for reading/writing, how to read/write the contents of a file.
+
+* [Chapter 6: Word Count](https://www.youtube.com/playlist?list=PLhOuww6rJJNOGPw5Mu5FyhnumZjb9F6kk): Writing a Python program to emulate the `wc` (word count) program. Validates and processes multiple file inputs as well as STDIN and creates output of the counts of lines, words, and bytes for each file optionally with a "total" if more than one file is provided.
+
+* [Chapter 7: Gashlycrumb](https://www.youtube.com/playlist?list=PLhOuww6rJJNMxWy34-9jlD2ulZxaA7mxV): Writing a Python program that processes an input file to build a lookup table (dictionary) that is used with multiple positional arguments to translate to the values from the file.
+
+* [Chapter 8: Apples and Bananas](https://www.youtube.com/playlist?list=PLhOuww6rJJNMe_qrKzw6jtxzHkTOszozs): Writing a Python program to find and replace elements in a string. Exploring multiple ways to write the same idea from for loops to list comprehensions to higher-order functions like map().
+
+* [Chapter 9: Abuse](https://www.youtube.com/playlist?list=PLhOuww6rJJNOWShq53st6NjXacHHaJurn): Writing a Python program to generate Shakespearean insults by randomly combining some number of adjectives with a randomly chosen noun. Learning about randomness, seeds, testing, how to use triple-quoted strings.
+
+* [Chapter 10: Telephone](https://www.youtube.com/playlist?list=PLhOuww6rJJNN0T5ZKUFuEDo3ykOs1zxPU): Using probabalistic and deterministc approaches to randomly mutating a string.
+
+* [Chapter 11: Bottles of Beer](https://www.youtube.com/playlist?list=PLhOuww6rJJNNGDXdGGfp3RDXBMhJwj0Ij): Writing a Python program to produce the verse to the "99 Bottles of Beer" song from a given starting point. Learning to count down, format strings, algorithm design. A focus on writing a function and unit test, exploring ways to incorporate our function to generate the verses from for loops to list comprehensions to map().
+
+* [Chapter 12: Ransom](https://www.youtube.com/playlist?list=PLhOuww6rJJNMxWhckg7FO4cEx57WgHbd_): Writing a Python program that will randomly capitalize letters in a given piece of text for the nefarious purpose of creating a ransom note. Exploration of for loops, list comprehensions, and the map() function.
+
+* [Chapter 13: Twelve Days of Christmas](https://www.youtube.com/playlist?list=PLhOuww6rJJNNZEMX12PE1OvSKy02UQoB4): Writing a Python program to create the verses for "The Twelve Days of Christmas" from a given day. Learning how to write a function and the test for it, then using the function in a list comprehension and a map to generate the output.
