Python Data Types

Python data types are the different types of data that can be stored and manipulated in a Python program. Python has several built-in data types, including numbers, strings, lists, tuples, dictionaries, and sets.

1. Numbers: Numbers are used to store numerical values. They can be integers (whole numbers), floats (decimal numbers), or complex numbers. Examples of numbers include:

- Integer: 5, -10, 0
- Float: 3.14, -2.5, 0.0
- Complex: 3+4j, -2+5j

2. Strings: Strings are used to store text values. They are enclosed in single or double quotes. Examples of strings include:

- 'Hello World!'
- "Python is awesome!"
- '12345'

3. Lists: Lists are used to store a collection of values. They are enclosed in square brackets and the values are separated by commas. Examples of lists include:

- [1, 2, 3, 4]
- ['apple', 'banana', 'cherry']
- [1.2, 3.4, 5.6]

4. Tuples: Tuples are used to store a collection of values. They are enclosed in parentheses and the values are separated by commas. Examples of tuples include:

- (1, 2, 3, 4)
- ('apple', 'banana', 'cherry')
- (1.2, 3.4, 5.6)

5. Dictionaries: Dictionaries are used to store key-value pairs. They are enclosed in curly brackets and the key-value pairs are separated by commas. Examples of dictionaries include:

- {'name': 'John', 'age': 20}
- {'fruit': 'apple', 'vegetable': 'carrot'}
- {1: 'one', 2: 'two'}

6. Sets: Sets are used to store a collection of unique values. They are enclosed in curly brackets and the values are separated by commas. Examples of sets include:

- {1, 2, 3, 4}
- {'apple', 'banana', 'cherry'}
- {1.2, 3.4, 5.6}
