🔧 Python Operators

Python operators are special symbols and keywords that tell Python to perform specific operations on your data. Think of operators as the action words of programming—they add, subtract, compare, combine, and manipulate information in your programs.

Understanding operators is essential because they're the building blocks you'll use to create logic, perform calculations, and make decisions in your code.

# Basic operators in Python
print("=== PYTHON OPERATORS ===")

# Math operators
a = 10
b = 3
print(f"{a} + {b} = {a + b}")       # 13
print(f"{a} > {b} = {a > b}")       # True

# Text operators
name = "Python"
print(f"Hello " + name + "!")       # Hello Python!

📂 Types of Operators

Python has several categories of operators, each designed for specific types of operations. Understanding these categories helps you choose the right tool for each programming task.

# Different types of operators
print("=== OPERATOR TYPES ===")

# Arithmetic
price = 25
tax = 5
total = price + tax
print(f"Total: ${total}")

# Comparison
age = 18
can_vote = age >= 18
print(f"Can vote: {can_vote}")

# Logical
has_license = True
is_adult = age >= 18
can_drive = has_license and is_adult
print(f"Can drive: {can_drive}")

💡 Why Operators Matter

Operators are fundamental to programming because they allow you to manipulate and work with data. Without operators, your programs would just store information without being able to do anything useful with it.

🔄 Common Operator Patterns

As you learn Python, you'll discover that certain operator patterns appear frequently in programming. Understanding these patterns will help you write better code.

# Common operator patterns
print("=== COMMON PATTERNS ===")

# Updating variables
score = 0
score += 10  # Add 10 to score
print(f"Score: {score}")

# Chaining comparisons
temperature = 75
comfortable = 65 <= temperature <= 80
print(f"Comfortable temperature: {comfortable}")

# Combining conditions
sunny = True
warm = temperature > 70
nice_day = sunny and warm
print(f"Nice day: {nice_day}")

⚡ Operator Precedence

Just like in mathematics, Python operators have a specific order of operations (precedence). Understanding this order helps you write expressions that work as expected and avoid common mistakes.

# Order of operations example
print("=== OPERATOR PRECEDENCE ===")

# Without parentheses
result1 = 2 ** 3 + 1
print(f"2 ** 3 + 1 = {result1}")  # 9 (exponentiation first)

# Chained comparison with logical operators
x = 15
result2 = 10 > 5 and 3 < 2
print(f"10 > 5 and 3 < 2 = {result2}")  # False

# Range checking
number = 15
in_range = 10 <= number <= 20
print(f"15 is between 10-20: {in_range}")  # True

🎯 Working with Different Data Types

Python operators work with different types of data, and understanding how they behave with strings, numbers, and boolean values will help you use them effectively.

# Operators with different data types
print("=== DATA TYPE OPERATIONS ===")

# Numbers
result = 5 + 3 * 2
print(f"Math: 5 + 3 * 2 = {result}")

# Strings
greeting = "Hello " + "World!"
repeated = "Hi! " * 3
print(f"String concat: {greeting}")
print(f"String repeat: {repeated}")

# Membership testing
fruits = ["apple", "banana", "orange"]
has_apple = "apple" in fruits
print(f"Apple in fruits: {has_apple}")

# Assignment shortcuts
count = 5
count += 3  # Same as: count = count + 3
print(f"After +=: {count}")
