What are some examples of normal functions in code?

Normal functions in code are reusable blocks that perform specific tasks. For example, in Python, you might have a function that calculates the area of a rectangle.

Can you show me the code for that function?

Sure! Here's a simple Python function:

def calculate_area(length, width):
    return length * width

What if I want to add error handling to that function?

You can add error handling using a try-except block. Here's an updated version:

def calculate_area(length, width):
    try:
        return length * width
    except TypeError:
        return 'Please provide numbers for length and width.'

That's helpful! Can you give me another example of a function?

Of course! Here's a function that checks if a number is even:

def is_even(number):
    return number % 2 == 0
