What type is {"name": "Ana", "age": 30} in Python?

Options

1. list: an ordered sequence of items
2. dict: a collection of key-value pairs (Correct option)
3. tuple: a fixed sequence of items
4. str: a piece of text

Answer

dict (dictionary): key-value pairs

Why

Basic Python types:

• int and float: numbers, like 30 and 3.5.
• str: text, like "Ana".
• bool: True or False.
• list: ordered items that can change, like [1, 2, 3].
• dict: key-value pairs inside curly braces. You read a value by its key: person["name"] gives "Ana".

Remember

{} with key: value pairs = dict.
