Lesson 3: Python programming

Strengthening: Use conditional statements to create a calculator. 

Excelling: Use iteration in a program to form a loop. 

CORRECT

CAUSE AN ERROR

print = ("Hello")

When need to cast to change the type of data that the user enters. 

We add the keyword INT before the input to change it.

Add this to your code

Creating a calculator

Using casting we can now create a calculator.

A value that is used by the program and can change is known as a...

1. constant
2. procedure
3. function
4. variable

Code that only runs when a condition is met is known as coding in...

1. Sequence
2. Selection
3. Iteration
4. Recursion

After every if, elif and else statement you put ...

1. ;
2. }
3. :
4. #

Which of the following if statements would cause an error

1. if name != "Fred":
2. if password == guess:
3. if name = "Bobby":
4. if age >= 18 :

Which symbol will check if two values are the same in a while condition?

1. !=
