A Comprehensive Guide to Python Data Types

Immutable Data Types

• Cannot be changed once created.

Examples:

- int: Whole numbers like 1, 2, 3

- float: Decimal numbers like 1.5, -3.14

- complex: Complex numbers like 1+2j

- str: Strings, e.g., "Hello"

- tuple: Ordered collections like (1, 2, 3)

- frozenset: Immutable version of a set

- bool: Boolean values like True, False

Advantages:

- Consistency: Once created, their values don’t change, making them reliable.

- Safe from Modification: Useful for fixed data and in multi-threaded programs where data consistency is critical.

Disadvantages:

- Less Flexible: You need to create new objects for any changes.

- Potentially Slower: Creating new objects repeatedly can slow down performance.

Mutable Data Types

Can be changed after creation.

Examples:

- list: Ordered collections like [1, 2, 3]

- dict: Key-value pairs like {"key": "value"}

- set: Unordered collections of unique elements like {1, 2, 3}

Advantages:

- Flexible: Easily modify content without creating new objects.

- Efficient: Updating content is usually faster and less resource-intensive.

Disadvantages:

- Risk of Inconsistency: Can be accidentally changed, leading to bugs.

- Thread Safety Issues: Can cause issues in multi-threaded programs if not managed carefully.

Python Data Types Summary

- Numeric Types: int, float, complex

- Sequence Types: str, list, tuple

- Mapping Type: dict

- Set Types: set, frozenset

- Boolean Type: bool

Python is dynamically-typed, meaning you don’t need to declare the type of a variable when creating it.
