Question

How would I count consecutive characters in Python to see the number of times each unique digit repeats before the next unique digit?

At first, I thought I could do

Answer 1

This is my simple code for finding maximum number of consecutive 1's in binaray string in python 3:

count= 0
maxcount = 0
for i in str(bin(13)):
    if i == '1':
        count +=1
    elif count > maxcount:
        maxcount = count;
        count = 0
    else:
        count = 0
if count > maxcount: maxcount = count        
maxcount
