Basic Functions

100

How do you print the statement: Hello World

print(Hello World)

200

How do you set a variable to an input?

x = input("enter x: ")

300

How do you create a function?

function():

400

Create a function that gets the user's name and prints it back to them.

function():

  name = input("what is your name?")

  print(name)

500

Create a function that gets 2 integers from the user and adds them together.

function():

  number1 = input("enter first number: ")

  number2 = input("enter second number: ")

  print(int(number1) + int(number2))

Variables & Operators

100

Create a variable x and set it to the string: "test"

x = "test"

200

print the sum of 3 and 5

print(3+5)

300

set variables to 9 and 4 and find the difference

num1 = 9

num2 = 4

difference = num1 - num2

400

what does the operator: // mean?

Floor Division, returns the largest possible integer

500

Create 3 integer variables and find the mean of them.

x = 1

y = 2

z = 3

mean = float(x + y + z) / float(3)

Data Types

100

What is an example of a string?

"hi"

200

What is an example of an integer?

21

300

What is the difference between an integer and a float?

Integer must be whole. Float can include decimals.

400

Give an example of a boolean.

number1 == number2

500

Why does this line of code not work?

sum = input() + 8

input() returns a string, which cannot be added with an integer. You must first cast it using int().

Casting & Concatenation

100

Cast the integer: 42 to a string

str(42)

200

Put together separate strings "Hello " and "World" to make one message.

message = "Hello " + "World

300

Turn the integer "36" into a string.

str("36")

400

Get the user's name and return: hi user_name

print("hi " + input("what's your name? "))

500

Get the user's age and return: you will be - in 4 years.

print("you will be " + str(int(input("age: ")) + 4) + " in 4 years")

Control Flow

100

What 2 values can a boolean return?

True, False

200

Write an if statement comparing 2 and 3.

if 2 == 3:

300

What does an else statement do?

The else statement is executed in the case that the if condition is false.

400

What are Python's 3 default Boolean Operators?

and (only returns true for Boolean if both are true)

or (returns true for Boolean if either of the arguments are true)

not (inverts modifying argument)

500

Ask the user for a number, if it is equal to 7, then return correct, but if not, return incorrect.

number = input("number: ")

if number == 7:

  print("correct")

else:

  print("incorrect")
