CMU CS Academy BUGS!

What is a bug?

Sometimes ​ (a)   does not work fine. When code does not work, we say it has a ​ (b)   . The reason that we call it a bug is that supposedly, a long time ago and actual bug crawled into a ​ (c)   and caused it not to work. And for that reason, we still call it a bug today.

What is one kind of bug explained in the video?

• Careless

• Typo

• Syntax Error

• Runtime Error

A syntax error is when you are not following the rules of ​ (a)   . (In the previous video) Python says you must have a closing ​ (b)   to match the open one, and if you don't, you have a syntax error. Notice how ​ (c)   gets drawn at all even though there is nothing wrong with the lines before the error. That is because when you have a syntax error, Python will not run your code at all until you ​ (d)   your bug.

• Python
• parenthesis
• nothing
• find and fix

What is another type of error according to the video?

• Syntax Error

• Spelling Error

• Runtime Error

• Division by zero Error

Another type of error is a ​ (a)   error. Notice that the first ​ (b)   did get drawn. That is because this is valid Python ​ (c)   so it's not a syntax error. But once it gets to line 5, when Python tries to draw our second rectangle, it ​ (d)   divide by 0. So the program stops running, it crashes. A runtime error is when your code runs but ​ (e)   while it is running.

• can not
• crashes

The third type of error that is shown in the video is?

• Logical Error

• Runtime Error

• Syntax Error

• Code Error

From the video in the previous question we get that it is not a syntax error because: ​ (a)   . It is not a runtime error because: ​ ​ (b)   . But it is still an error because​ (c)  

• It's proper Python code, and the code runs
• It didn't crash like when we divided by 0
• it doesn't do what we need to do.

Match the following

• Logical Error

• 
• Syntax Error

• 
• Runtime Error
