Python Tutorial - Part 2: Data Types and Variables

Welcome back to our Python tutorial series! In this second part, we'll explore Python's built-in data types and how to work with variables.

Python Variables

Variables in Python are used to store data values. Unlike many other programming languages, Python has no command for declaring a variable.

name = "Alice"
age = 25
height = 5.6

Basic Data Types

Python has several built-in data types:

Numbers

• int: Integer numbers (e.g., 42, -17)
• float: Decimal numbers (e.g., 3.14, -0.5)

integer_number = 42
floating_number = 3.14159

Strings

Text data is represented as strings in Python.

greeting = "Hello, World!"
multiline_text = """This is a
multiline string"""

Booleans

Boolean values represent True or False.

is_python_fun = True
is_difficult = False

Type Checking

You can check the type of any variable using the type() function:

print(type(42))        # <class 'int'>
print(type(3.14))      # <class 'float'>
print(type("Hello"))   # <class 'str'>

What's Next?

In Part 3, we'll dive into Python collections: lists, tuples, and dictionaries. These are fundamental data structures you'll use constantly in Python programming.
