#Problem 5: Write a function def even_list(my_list) that has one 
#parameter - list of integers. The function creates and returns TWO new 
#lists: list of all even elements from my_list, and list of all positions 
#(INDEX)(PLACE) of even elements in my_list Write main to test your 
#program. 


#Example: my_list=[1, 4, 5, -10, 3, 5, -12, 4]
#index=[0,1,2,3,4,5,6,7]

#evens=[4, -10, -12, 4]
#positions=[1, 3, 6, 7]
