Is it possible to implement functions in Python, and how to do it?

Yes, in Python, functions are very easy to implement using the keyword def. A function can accept arguments and return a value. Here's an example:

# Defining a function that adds two numbers
def add(a, b):
    return a + b

result = add(3, 5)
print(result)  # Outputs 8

Functions help structure code, reuse logic, and make the program more readable.
