TypeError: __init__() missing 1 required positional argument: 'name'

You’re calling a function without all the required arguments.

Fix 1: Pass all required arguments

class User:
    def __init__(self, name, email):
        self.name = name
        self.email = email

# ❌ Missing email
user = User("Alice")

# ✅ Pass all arguments
user = User("Alice", "alice@example.com")

Fix 2: Forgot self in method call

class Calculator:
    def add(self, a, b):
        return a + b

# ❌ Calling on the class, not an instance
Calculator.add(1, 2)

# ✅ Create an instance first
calc = Calculator()
calc.add(1, 2)

Fix 3: Add default values

def greet(name, greeting="Hello"):
    return f"{greeting}, {name}!"

greet("Alice")  # Works — greeting defaults to "Hello"
