07:12 Lesson 30.2 Horizontal Notation Lesson 30.2 Horizontal Notation	Lesson 30.2 Horizontal Notation Sorting algorithms can be quite sophisticated. In order to understand them, we need some way to visualize them. In this video, we introduce horizontal notation, which is a way to track how much of a… dot region notation range things sorting loop numbers regions picture n. sort python videos box invariants portions pictures statements assignment From Hannah Lee 40 plays
10:43 Lesson 29.1 Multitasking Lesson 29.1 Multitasking	Lesson 29.1 Multitasking To understand coroutines, we have to understand a little bit about their history first. Coroutines are a form of multitasking. This is what we informally call the act of running multiple programs at… switching threads routines parallelism server programs java concurrency game assignment client window topic things python language systems machines machine computer From Hannah Lee 60 plays
06:43 Lesson 28.9 Dictionary Comprehension (OPTIONAL) Lesson 28.9 Dictionary Comprehension (OPTIONAL)	Lesson 28.9 Dictionary Comprehension (OPTIONAL) This video is not optional because the material is advanced. It is optional because this video series has run long and this topic is less important for you to know. While we have not talked about… dictionary comprehension things grades generator string python key method bonus pattern accumulator expression keys iterable incomprehension lot disadvantages student students From Hannah Lee 26 plays
05:16 Lesson 28.7 Iterator Chaining Lesson 28.7 Iterator Chaining	Lesson 28.7 Iterator Chaining Generators take iterators as input, but they also produce one as output. In this video we show how to chain iterators together, doing complex operations on our data. tools things chain module generator filter generators output types thing functions object average input tuple iter python documentation programming running From Hannah Lee 42 plays
09:34 Lesson 28.4 Generator Visualization Lesson 28.4 Generator Visualization	Lesson 28.4 Generator Visualization Generators look like normal functions, but they do not behave like them. In this video we show how to visualize them, using the Python Tutor. call frame return generator function statement yield loop constructor counter instruction python error parameter notice folder thing class range tutor From Hannah Lee 56 plays
06:23 Lesson 28.3 The yield Statement Lesson 28.3 The yield Statement	Lesson 28.3 The yield Statement Making iterator classes is hard. In this video, we show an alternative, allowing us to write the iterator as a ‘function”. This requires the addition of a new python statement, the yield… function loop iterator statement elements yield return call definition generator python things visualization minute frame object a. huh difference outputs From Hannah Lee 58 plays
07:38 Lesson 28.2 Iterable Classes Lesson 28.2 Iterable Classes	Lesson 28.2 Iterable Classes In this video, we show how to make our own iterable and iterator classes. These are actually tightly linked, and you need one to create the other. iterator function iterable range loop object method times attribute class constructor underscore element iter limit attributes shot classes python demand From Hannah Lee 70 plays
07:34 Lesson 28.1 Iterators Lesson 28.1 Iterators	Lesson 28.1 Iterators We are familiar with iterables, types that we can use in a for-loop. In this video we introduce the iterator. This is a type that can be used in a for-loop, but we can also manually step through the… loop iterator files function element contents elements range memory python sequence interval iterable object iterators alright crash a. folder y. From Hannah Lee 66 plays
09:37 Lesson 27.9 Model-View-Controller Lesson 27.9 Model-View-Controller	Lesson 27.9 Model-View-Controller When we break up out application in multiple classes, we need to give each class a role. One of the most popular ways to do this is designate a class as a model, a view or a controller. In this video… controller model classes class centigrade application thing fahrenheit pattern folder things attribute script models game lot python gay stuff py From Hannah Lee 59 plays

06:05 Lesson 26.5 While-Loops vs For-Loops Lesson 26.5 While-Loops vs For-Loops	Lesson 26.5 While-Loops vs For-Loops We can always replace for-loops with while-loops, but should we? In this video we talk about the trade-offs of the two control structures and why it might be better to use over the other. loop fibonacci loops sequence squares variable function range thing bugs module n. things python iterator specification accumulator elements calculation recursion From Hannah Lee 67 plays
08:46 Lesson 26.2 While-Loop Traces Lesson 26.2 While-Loop Traces	Lesson 26.2 While-Loop Traces While-loops can do everything that a for-loop can (and more) but they are much harder to use. That is why, in this video, we talk about how to debug a while-loop before we talk about how to write… loop loops accumulator function things tutor squares trace python sum flow x. variable body numbers lot control debugging statements print From Hannah Lee 71 plays
08:15 Lesson 26.1 The While-Loop Lesson 26.1 The While-Loop	Lesson 26.1 The While-Loop In this video we talk about the while-loop and explain why it is necessary. In particular, there are types of iteration that are not possible with the for-loop. loop expression times loops variable script statement elements body iterator accept chance lines difference statements iteration inside problem letter python From Hannah Lee 77 plays
05:24 Lesson 25.1 Error Types Lesson 25.1 Error Types	Lesson 25.1 Error Types In this video we revisit error messages in Python and show how to read the error type. This type is a class, which means that you can construct your own error objects. error class exception assertion python stack things folders base object trace zerodivisionerror colon parent subclass instance fact errors arithmetic exceptions From Hannah Lee 70 plays
08:56 Lesson 24.4 Duck Typing Lesson 24.4 Duck Typing	Lesson 24.4 Duck Typing This partial typing from the previous video has a name. It is called duck typing. In this video we show both why this is so popular among Python programmers and also why it is so controversial. duck point typing fraction attributes object types denominator numerator instance language programming times function bugs languages getter python class ease From Hannah Lee 72 plays
