Question

Which answer correctly defines two parameters x and y for a function definition: def calc_val(...)?

How would you correctly define x and y in a Python function?

a) (x, y)
b) x, y
c) x, y
d)

Answer 1

To define parameters x and y in a Python function, they are included within parentheses in the function definition as (x, y). This follows Python's syntax for defining function parameters, where x can be seen as the independent variable and y the dependent variable, mimicking their roles in mathematical equations.

Step-by-step explanation:

To correctly define two parameters x and y for a function definition in Python, you would define them within the parentheses in the function signature. Therefore, the correct answer would be option a) (x, y). Here's an example of how you can define this in a function:

def calc_val(x, y):
# your code here

Within the function, x is usually used as the independent variable while y is the dependent variable. For instance, in a mathematical equation, you would substitute a chosen value for x and solve for y. In Python, these variables work similarly when you pass arguments to the function.

Here's a simple example to illustrate their roles:

def calc_val(x, y):
return x + y
print(calc_val(2, 3)) # outputs 5
