Find maximum length of consecutive repeated numbers in a list

Question

My question is how to find the maximum length of consecutive repeated numbers (or elements in general) in a list. I wrote the following function which works fine but I was w

Answer 1

longest_fragment = 0
current_fragment = 0

a = int(input())
last_input = a # why do I assign last_input here?
while a:
    if a == last_input:
        current_fragment += 1
    else:  # why is current_fragment assigned 1 in this clause?
        if current_fragment > longest_fragment:
            longest_fragment = current_fragment
            current_fragment = 1
    last_input = a
    a = int(input())

longest_fragment = max(longest_fragment, current_fragment) 
# why didn't i use max in the loop?
# why am I checking again down here anyway?

print('The longest fragment was:', longest_fragment)
