7-4-Make

Task – Make

In the make tasks, students use the skills learned in the earlier stages of PRIMM to create their own program based on a description of what it should do.

Make sure that the students add comments to explain what the code does.

If…Else Statements

What is it

These are statements that allow Python to perform different tasks in different situations.

This is used all the time in real life. One example could be:

IF it is raining, THEN I will take my umbrella

In the example, the second part ONLY happens if the first part is true.

Boolean conditions

If…Else statements rely on a boolean condition to decide whether or not to run the code.

Boolean conditions check if something is True or False.

Boolean conditions are written using logical operators. These are:

Operator	Definition	Example
`==`	Equal to/Same as (a single = is used to store data in a variable, so Python uses double = to compare two pieces of data)	`if weather == "rain"` If it is raining
`!=`	Not Equal to	`if weather != "snow"` If it is not snowing.
`>`	Greater than	`if age > 10` If the age is greater than 10.
`>=`	Greater than or Equal to	`if age >=10` If the age is greater than 10, OR if the age is 10.
`<`	Less than	`if age < 18` If the age is less than 18
`<=`	Less than or Equal to	`if age <=18` If the age is less than 18, OR if the age is 18

When using the == operator, case matters. Hello World is not equal to hello world.

Code Examples

# Code with one statement
if condition:
    print("Run this code")

# Code with else statement
if condition: 
    print("Run this code if the condition is True")
else: 
    print("Run this code if the condition is False")

Help! My Code Does Not Work!

Make sure to check your code for the following things:

A colon at the end of each if and else line.
Each branch is indented unsing the TAB key (not just spaces)
No condition after ‘else’
A double equals in the condition (==) when checking that two pieces of data are the same.
