Can anyone help me with the logic behind this code?

Question

def calc(x):
p=4*x
a=x*x
return (p,a)
side = int(input())
p, a = calc(side)
print("Perimeter: " + str(p))
print("Area: " + str(a))

Answer 1

What specifically don't you get?

it defines a function that returns a tuple of two values. first is the x parameter times 4 and second is x squared. Then it prints the values

Answer 2

So is side= x?

Answer 3

No, x is a parameter in the function, it can be any number. 'side' is a specific number given from input. You just use it as an argument for the function so the value passes down.
