= is to assign a value to a variable

== is used to compare the value of two variables

400

What are the four main types of data types?

- Strings (str)

- Integers (int)

- Floats (float)

- Boolean (true/false)

500

To specify a variable type, what would you use to denote integers, floats, and strings?

Commands

100

Which command will display the text 'Hello world!' on the screen? 

A) print(Hello world!) 

B) print("Hello world!")

C) print "Hello world!" 

D) print = "Hello world!"

B) print("Hello world!")

Which command will correctly ask the user for their age? 

A) age = input(How old are you?) 

B) input("How old are you?") = age 

C) How old are you = input() 

D) age = input("How old are you?")

D) age = input("How old are you?")

300

In the following example, Is myName a string, a function, a variable, or a method?

myName = input()

Variable

400

What is the result of this command? print ("5" + "3") 

A) 8 

B) "8" 

C) "5" + "3" 

D) 53

500

The following code would not run. What is wrong with it, and how can it be fixed?

name = "Bob"

print(Name)

"Name" is supposed to print, but there's no variable "Name". It needs to be uncapitalized as "name" for it to print "Bob".

200

What does input do? 

A) It allows users to change the program 

B) It allows a user to solve a task 

C) It converts data types 

D) It allows users to enter data

D) It allows users to enter data

300

What would happen in the following: number = int('5.0')

a. Converts to integer, becoming 5

b. Keeps as a string

c. Gets an error

c. Gets an error

400

Which of these codes tests whether the variable x is the same as 'Hello'? 

A) x = "Hello" 

B) x == "Hello"

C) x != "Hello" 

D) x <> "Hello"

B) x == "Hello"

500

What would the output of this program be?
