How do i start the second part

def L4(p):
    x=[]
    for i in range (10):
        x.append(randrange(1,7,1))

if
Part 1 The function that takes an input parameter an empty list. It then creates a list 10 elements long, each consisting of a random number between 1 and 6.
Part 2 Using in and slicing,its supposed to check to see if any of the elements occurred twice. If so, use the index function and slicing to check to see if it occurs 3 times in the list. If so, using the index and the slicing, check to see if it occurs 4 times. A variable to keep track of the largest number of occurrences.

What part do you not understand. It seems pretty straight forward to me. Using "in" to find duplicates, if a number is found a second time, slice off the first part of the list and check the remaining list, and do this until it is not found.

found = True
while found:
    if num in some_list:
        ## slice, add one to a counter
    else: 
        found = False
 
if ctr > largest_occur:
    largest_occur = ctr
