Help in Python please

2) Using a while loop, write a function called product_evens (n) that takes a positive integer n as an argument and returns the product of the positive even integers less than or equal to n. You can assume the argument n will be an integer greater than or equal to 3. For example, the function call product_evens(7) should return 48 , since 2x 46 is 48 . The function call product_evens (10) should return 3840, since 2468 x10 is 3840
