CBSE 10th Class Unit 2 - Knowledge of data types

 

Data Types

• Number:
• Integer: Whole numbers (e.g., 10, -5, 0).
• Float: Real numbers with decimal points (e.g., 3.14, -2.5).
• Complex: Numbers with real and imaginary parts (e.g., 2+3j).
• Boolean: Represents truth values (True or False).
• Sequence:
• String: An immutable sequence of characters (e.g., "Hello").
• List: A mutable ordered collection of elements (e.g., [1, 2, 3, "a"]).
• Tuple: An immutable ordered collection of elements (e.g., (1, 2, 3)).
• None: Represents the absence of a value.
• Mapping:
• Dictionary: An unordered collection of key-value pairs (e.g., {"name": "Alice", "age": 30}).
• Mutable: Data types whose values can be changed after they are created (e.g., lists, dictionaries).
• Immutable: Data types whose values cannot be changed after they are created (e.g., strings, tuples, numbers).
