Making Decisions
Python: Booleans
Master the logic of True and False - the foundation of all computer logic.
The Hook
A Boolean is like a Light Switch.
It can only be in one of two states: True (On) or False (Off). Computers use these two values for every single decision they make.
Logic & Comparisons
Python evaluates questions like "Is 10 bigger than 5?" into a Boolean.
is_sunny = True
# Note the capital T
game_over = 10 > 5
# 10 > 5 is True
is_winner = 10 == 100
# 10 == 100 is False (== means 'equal to')

Predict
What exactly will this logic print?
score = 100
print(score > 200)
print(score > 200)
