Variables and Types

100

How many types of variables have we learned about so far this year?

3

200

What are the types of variables that we have learned so far this year?

String, Int, Float

300

What types of variables are the following:

5.0

5

"5.0" 

Float

Int

String

400

Tell me why all integers/floats can be strings, but not all strings can be integers/floats.

Because letters cannot be turned into numbers, python will give us a typeError.

500

What will be the output of my program?

1variable = 24

print(24)

Error.

csp = input("Input a string: ")

200

How do I get user input of a int? Write in on the board...

name of variable is csp

csp = int(input("Input a string: "))

300

How do I get user input of a float? Write in on the board...

name of variable is csp

csp = float(input("Input a string: "))

400
