Could someone find the mistake, i ran this script but it printed incorrectly i guess

Question

print("money: ",money)
b = str(input("input: "))
print(b)
print("-coffee 2000\n-gundam 10000 \n")

if b=="coffee" or "Coffee":
money-=2000
if money<0:
print("you dont have enough money")
else:
print("your money: ",money)

elif b=="gundam" or "Gundam":
money-=10000
if money<0:
print("you dont have enough money")
else:
print("your money: ",money)
else:
print("error")

Answer 1

after "or" you need whole expression so b=="coffee" or b=="Coffee" the same with "gundam"

Answer 2
