Study Notes

Practice 4 Plan

Homework from Practice 3 should be completed
Python statements: if, elif, and else will be covered
Practice exercises will be conducted
Quiz 1 will be taken

Python Statements Part 1: if, elif, else

if, elif, and else statements are used to control the flow of execution in Python based on conditions
if statements are used to execute code only if a certain condition is true
elif statements (short for "else if") provide additional conditions to check if the previous if or elif conditions are false
else statements execute code if none of the preceding if or elif conditions are true

Task # 1

The provided code snippet uses if and else statements to create different outputs based on the value of the room variable
The if statement checks if room is equal to "kit" and prints "looking around in the kitchen." If it is not equal to "kit", the else statement executes and prints "looking around elsewhere."

Task # 2

The task instructs you to add an else statement to the second control structure, which checks the value of the area variable
The else statement should print "pretty small" if the condition area > 15 evaluates to False

Task # 3

The task instructs you to customize the conditional statements further by introducing elif statements
Using elif, you can add additional conditions to check if the value of room is equal to "bed" and print “looking around in the bedroom."
In the second control structure, you should add an elif statement to print "medium size, nice!" if the value of area is greater than 10 but not greater than 15.

Task # 4

The task involves adding an elif statement to the second control structure to output a tailored message for different area values
The elif statement should check if area is greater than 10 and less than or equal to 15 and then print “medium size, nice!”

Quiz 1

The quiz will be paper-based and worth 10% of the overall grade
