09:18 Lesson 25.2 Error-Specific Recovery Lesson 25.2 Error-Specific Recovery	Lesson 25.2 Error-Specific Recovery In this video we show how to use the error type to give you more control over a try-except statement. You can chose to recover from some errors, while completely ignoring other errors. error assertion function script float string exception instance statement typing letter bounds problem range air expressions aha accepts types trace From Hannah Lee 66 plays
05:58 Lesson 14.4 Try-Except and Testing Lesson 14.4 Try-Except and Testing	Lesson 14.4 Try-Except and Testing We have a new control structure, so it is time once again to talk about testing. In this video we revisit the concept of code coverage and show testing a try-except is very similar to testing a… function test slash string precondition float cases branches frack statement problem division answer integer possibilities specification fraction works mind script From Hannah Lee 57 plays
04:58 Lesson 14.2 Functions with Try-Except Lesson 14.2 Functions with Try-Except	Lesson 14.2 Functions with Try-Except Try-except statements will allow use to write functions that we could not write with conditional statements. In this video, we show how to use try-except as a general programming tool. float notation function forgiveness conditionals string specification reason lot idea languages programming permission difference period decimals examples pseudocode error statement From Hannah Lee 62 plays
06:47 Lesson 14.1 Try-Except Statements Lesson 14.1 Try-Except Statements	Lesson 14.1 Try-Except Statements In this video we intrduce a new control structure: the try-except statement. As we will see, it looks very similar to an if-else statment with some important differences. function script problem float statement input definition crash accept tools error string body types trie control python idea programmer screen From Hannah Lee 77 plays
06:53 Lesson 12.1 Objects Everywhere Lesson 12.1 Objects Everywhere	Lesson 12.1 Objects Everywhere The biggest lie that we have told is that there is a difference between classes and the basic types. In this video we show that this is not true, and what ramifications this has for Python. folder python string int objects object types folders abc boolean float function method things series error class thing box constructor From Hannah Lee 88 plays
04:54 Lesson 11.6 Attribute Invariants Lesson 11.6 Attribute Invariants	Lesson 11.6 Attribute Invariants When you work on Assignment 3, you will discover that the color objects have some significant restrictions on how they can be used. These restrictions are called attribute invariants, and they are… object preconditions class attributes invariance classes function color documentation cs intro invariants rgb invariant float dot integers values webpage objects From Hannah Lee 98 plays
04:47 Lesson 7.4 Preconditions Categories Lesson 7.4 Preconditions Categories	Lesson 7.4 Preconditions Categories In this video, we break our preconditions up into categories. The primary reason for this is to help us analyze a specification. It will also become extremely imporant when we talk about enforcement… precondition float restriction string operations sense specification variable condition pre function language restrictions languages definition tools text x. values preconditions From Hannah Lee 68 plays
04:12 Lesson 7.3 Preconditions Lesson 7.3 Preconditions	Lesson 7.3 Preconditions The one thing that we have not talked about yet are the preconditions in a specification. However, as this video shows, they are arguably the most important part of the specification. They are what… function precondition person specification developer microsoft preconditions definer float specifications fault tools developers string hand return centigrade call parameter grade From Hannah Lee 72 plays
05:53 Lesson 3.1 Built-In Functions Lesson 3.1 Built-In Functions	Lesson 3.1 Built-In Functions The easiest functions to use in Python are those that are built into it. They are listed on the Python Documentation page. In this video we examine some of these and show the syntax for how to use… function parentheses call functions expression python float int word arguments argument integer calls quit return expressions math webpage documentation answer From Hannah Lee 132 plays
03:41 Lesson 2.4 Dynamic Typing Lesson 2.4 Dynamic Typing	Lesson 2.4 Dynamic Typing If you have programmed before (and it is okay if you have not), you may be used to variables having the restriction that they can only contain specific types. This is not the case in Python, and that… word expression string variables float class things values variable python thing programs numbers error fact languages int mind types language From Hannah Lee 105 plays
03:20 Lesson 2.2 Assignment Statements Lesson 2.2 Assignment Statements	Lesson 2.2 Assignment Statements Now that we have some idea of what a variable is, it is time to start creating them. We do that with assignment statements, which are the subject of this video. python command box names expression statement assignment expressions x. e3 e1 underscore numbers letters symbol statements variables underscores operator float From Hannah Lee 110 plays
02:27 Lesson 2.1 Notion of a Variable Lesson 2.1 Notion of a Variable	Lesson 2.1 Notion of a Variable Variables are tricky things because they are often invisible. To better understand them, we need to build a mental model of how they work. That is the purpose of this video. python box variables boxes things thing values float memory expressions variable concept restrictions java languages int notice tool locations x.

04:33 Lesson 1.7 Mixed Expressions Lesson 1.7 Mixed Expressions	Lesson 1.7 Mixed Expressions For the most part, operations are used to combine two expressions of the same type.
