Highest Number Of Consecutively Repeating Values In A List

Let's say I have this list: List= [1,1,1,0,0,1,1,1,1,1] How do I display the highest number of repeating 1s in a row? I want to return 5.

Solution 1:

I don`t really understand the question, but if you want the highest number of consecutive elements in list, maybe something like this

from itertools import groupby

list = [1,1,1,0,0,1,1,1,1,1]
count_cons_val = [sum(1for _ in group) for _, group in groupby(list)]
print(max(count_cons_val))

Output:

5

Solution 2:

Find my comments how this answer helps you out inline after the # tag.

save = None
count = 0
best = 0
for i in list:
    if i == save:
        count += 1 # if it's the same as last add 1 to count
        best = count
    else: #if it is different reset with the new element
        count = 0
        save = i

print(best)
