exercise_1.py — Age category

Ask the user for their age with input(), cast it to int. Using if/elif/else, print "child" if under 13, "teen" if 13-17, and "adult" otherwise.

Example run (input is 15):

How old are you?
15
teen

exercise_2.py — Fix the bug

This code always prints "Weekend!", even on a Monday. Copy it into exercise_2.py, then fix the condition so it only matches Saturday or Sunday.

day = input("What day is it?\n").strip().lower()

if day == "saturday" or "sunday":   # BUG: fix this condition
    print("Weekend!")
else:
    print("Not the weekend.")

Expected output (for an input of monday):

What day is it?
monday
Not the weekend.

exercise_3.py — Grade calculator

Ask the user for a score with input(), cast it to int. Using if/elif/else, print the letter grade: A for 90 and above, B for 80-89, C for 70-79, otherwise F.

Example run (input is 82):

Enter your score:
82
Grade: B

exercise_4.py — Comfortable temperature

Ask the user for a temperature with input(), cast it to float. Use a chained comparison (18 <= temperature <= 25) to print True if it's comfortable, False otherwise.

Example run (input is 22):

Enter the temperature:
22
Comfortable: True

exercise_5.py — Bonus: one-line status

Ask the user for their age with input(), cast it to int. Using a one-line conditional expression (ternary), set status to "adult" if age >= 18 else "minor", and print it.

Example run (input is 16):

How old are you?
16
minor
