Python Data Types

Python has several built-in data types that are used to store different kinds of information. Understanding these is fundamental to programming in Python.

1. Numbers

Python supports integers, floating-point numbers, and complex numbers.

x = 5        # Integer
pi = 3.14    # Float
z = 2 + 3j   # Complex number

2. Strings

Strings are sequences of characters, used to store text.

name = "Alice"
greeting = 'Hello, world!'

3. Booleans

Booleans represent True or False values.

is_active = True
is_admin = False

4. Lists

Lists are ordered, mutable collections of items.

fruits = ["apple", "banana", "cherry"]
fruits.append("orange")

5. Tuples

Tuples are ordered, immutable collections.

point = (10, 20)

6. Dictionaries

Dictionaries store key-value pairs.

person = {"name": "Alice", "age": 30}

7. Sets

Sets are unordered collections of unique items.

unique_numbers = {1, 2, 3, 2}
# unique_numbers will be {1, 2, 3}
