How do you define a user-defined function in Python?

a) Using the define keyword

b) Using the function keyword

c) Using the def keyword

d) Using the fun keyword

Answer:

c) Using the def keyword

Explanation:

You define a user-defined function in Python using the def keyword, followed by the function name and parentheses. Inside the parentheses, you can define parameters if needed. The code block that follows the def statement is the body of the function, which contains the statements that the function will execute.

def greet(name):
    print(f"Hello, {name}!")  # This function takes a name as input and prints a greeting

User-defined functions allow you to create custom functionality tailored to your specific needs, making your code more reusable and modular.

Understanding how to define and use user-defined functions is crucial for organizing your code and solving complex problems in a structured way.
