Can you give an example of calling a function in Python and explain how it works?

Calling a function in Python is the process of transferring control to a specific block of code that performs certain actions and may return a result.

Example:

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

message = greet("Anna")
print(message)  # Will output: Hello, Anna!

Explanation:

• def greet(name): — declares a function with the parameter name.
• When calling greet("Anna"), the string "Anna" is passed to the function.
• The function constructs a greeting string and returns it.
• The result is stored in the variable message and displayed on the screen.
