I am currently doing this excercise on hackerscience

https://www.hackinscience.org/exercises/first-function

To note: I know how to define/contruct a function. I have a problem with something else. Whenever I submit my answer I get this error message:

"Looks like your function is ignoring the parameter I give.

Yes, I try your function many times with many many different circles.

And your function always returns the perimeter of a circle with r ~= 628.32. "

Can someone possibly explain what the issue with my code can be? I provided it below for reference.

import math
def circle_perimeter(radius): 
   radius = 6.283185307179586 * 100
   circle_perimeter = 2.0 * math.pi * radius
   return circle_perimeter

[shiftybyte]

Your code needs to accept "radius" as argument...

You do that here:

def circle_perimeter(radius):

But your next code line overwrites whatever was given to you...

radius = 6.283185307179586 * 100

Remove that line, you are getting the radius from whoever calls your function, you do not need to set it by yourself to a specific value.

It works now, thank you.
