Hi Jazmin,
Let's take a look at each component of this task.
Create a function named square. It should define a single parameter named number.
Create a function named square.
Functions are created (or defined) with the keyword def and a function name is its identified that follows the def keyword, doesn't have spaces, and ends in parentheses.
Python
def square():

It should define a single parameter named number
Parameters (which are sometimes referred to as arguments) are the variables that go inside the parentheses, and they can be used by the function based on their name. So if I had a function that looked like:
Python
def draw_circle(radius_in_pixels, color):
 
The function name is make_paper, it has one two parameters the first is named radius_in_pixels and the second is named color
If I call the function somewhere else in my program I would do it as below. When we call the function we include arguments in the function call, the values of our arguments become the values of the parameters within the function
Python
draw_circle(5, "green")

So within our function:
Python
def draw_circle(radius_in_pixels, color):
        # radius_in_pixels would be equal to an integer of value 5, if called as above
        # color is a string containing "green", if called as above
        # for instance, we might write:
        diameter_in_pixels = radius_in_pixels * 2
