500

This pair of keywords is used to handle errors and prevent your program from crashing.

What are try and except? 

Find the Error

100

age = 16

print("You are " + age + " years old.")

What is a TypeError? 

200

x=5 

if x =2:

    print("This number is 2.")

else: 

    print("This number is not 2.")

What is a missing equal sign? 

300

positive = 10

while positive > 0:

    print("This number is positive")

What is an infinite loop? 

400

def add(a, b): 

    return a + b

add(2)

What is missing a parameter? 

500

def square(n):

    result = n * n

print(square(5))

What is a missing return statement? 

Predict the Output

100

x = 5

print(x+3)

What is 8?

200

for i in range(3):

    print(i)

What is 0, 1, and 2

300

for i in range(5, 1, -1):

    if i % 2 == 0:

        print(i)

What is 4 and 2?

400

for i in range(5):

    if i % 2 == 0:

        continue

     print(i)

What is 1 and 3?

500

x = 3

def update(x):

    x = x + 2

    return x

update(x)

print(x)

What is 3?

Strings

100

This is the result of the following: 

print("Hi" + "class")

What is "Hiclass"?

What is "random stuff y"

Random

100

The four different variables we have talked about 

integers, floats, booleans, and strings

200

These are used to document your functions and provide those reading your code with explanations as to how your code works. 

What are comments?

300

Difference between using a set of if statements vs elif statements.
