How do you find a price by name in Python?
Short answer. Store it in a dictionary and use the name as the key.
Can a dictionary have two same keys?
No. Keys are unique.
Remember
| Key: what you search by |
| Value: what you get back |
| Keys are unique |
How do you find a price by name? Use a dictionary. Tea is a key, and ten its value. A colon joins each pair, in curly brackets. Menu at poha gives twenty five. The key is what you search by. The value is what you get. Keys are unique.
