if, elif and else

python

amount = 750

if amount >= 1000:

    tier = "high"

elif amount >= 500:

    tier = "medium"

else:

    tier = "low"

print(tier)

OUTPUT

medium

Python checks conditions from top to bottom and runs the first one that's True. Combine checks with and, or and not.

python

city, is_paid = "Pune", True

if city == "Pune" and is_paid:

    print("ship from the Pune warehouse")

watch out == compares two values. A single = assigns a value. Mixing them up is one of the most common beginner bugs.
