📚 Quick Study Guide

  • 🧠 Function Definition: A block of organized, reusable code that performs a specific task. Functions are defined using the `def` keyword in Python.
  • ⚙️ Function Call: Invoking or executing a function by its name, passing any required arguments.
  • ➡️ Arguments: Values passed to a function when it is called. These allow you to customize the function's behavior.
  • 🔑 Parameters: Variables listed inside the parentheses in the function definition. They receive the arguments passed during the function call.
  • ↩️ Return Value: A function can optionally return a value using the `return` statement. If no `return` statement is present, the function returns `None`.
  • 💡 Scope: Refers to the visibility of variables. Variables defined inside a function have local scope, meaning they are only accessible within that function.
  • 📝 Example: python def add(x, y): return x + y result = add(5, 3) # Calling the function with arguments 5 and 3 print(result) # Output: 8
