400

How do you end an ELIF statement?

With an else

500

num = 200

if num > 50: 

    print("This is a big number!")

Modulo

100

You have 5 cupcakes and 3 friends. How many cupcakes will you have left if each friend has an equal amount of cupcakes?

5%2 = 

2

200

You have 10 cupcakes and 5 friends. How many cupcakes will you have left over if each friend receives an equal amount?

10%5 = 

0

300

Now you have 9 cupcakes and 4 friends. How many cupcakes will you have left over if each friend receives an equal amount?

9%4 = 

1

400

Now you have 4 cupcakes and 7 friends. How many cupcakes will you have left over if each friend receives an equal amount?

4%7 = 4

500

Now you have 10 cupcakes and 2 friends. How many cupcakes will you have left over if each friend receives an equal amount?

10%2 = 0

Errors

100

The process of fixing errors is called...

debugging 

200

This error occurs when you have violated the rules of python syntax. It can't understand what you are trying to do. 

Syntax error

300

What type of error is this? 

numerator = 10

denominator = 0

result = numerator / denominator

print(result)

run time error, because it is happens when the code tries to perform an operation that is not allowed. 

400

What kind of error is this?

# Program to calculate the average of two numbers

a = 5

b = 7

average = a + b / 2   # Incorrect calculation of average, it should be (a+b)/2

print("The average of", a, "and", b, "is", average)

Logical error, because it the code does not produce the expected output due to incorrect logic or algorithm. 

500

What are the steps to fixing errors?

1. Read the error message carefully: When an error occurs, the computer will usually give you an error message that explains what went wrong.

2. Identify the line(s) of code causing the error: The error message will usually give you a line number or point to the specific line(s) of code that caused the error. 

3. Use print statements: You can use print statements to help debug your code. You can add print statements to the code to check the values of variables or to see if the code is executing as expected.

4. Test the code: Students should test their code by running it with different inputs to see if it produces the expected results.

5. Repeat the process: If the code still doesn't work, you should repeat the process, starting from step 1, until you find and fix the error.

Lists

100

Each value in a list is called...

an item

200

What number do you start with in indexing?

0

400

What will print in the console? 

my_list = ["a", "b","c"]

print(my_list[1])

b

500

What will print in the console? 

str_list = [“p”, “r”, “o”, “b”, “e”]

print(str_list[0])

print(str_list[4])

print(str_list[-5])
