문자열 split 및 반복 확인 코드
https://programmers.co.kr/learn/courses/30/lessons/60057

Tips.
1.일정 단위로 문자열 나누는 코드는 직접 짜기
2. return min(함수, for in)으로 짜보자

def short_str(s,n):
    sub_word = [s[i:(i+n)] for i in range(0,len(s),n)]
    short = []
    
    previous, rep = sub_word[0], 1
    for sw in sub_word[1:-1]:
        if sw == previous:
            rep += 1
        else:
            short.append(rep)
            previous, rep = sw, 1
    if sub_word[-1] == previous:
        short.append(rep+1)
    else:
        short.append(rep)
    
    return len("".join([str(sh) for sh in short if sh >1]))+(len(s)-(sum(short)-len(short))*n)
         


def solution(s):
    short_len = [short_str(s,n) for n in range(1,int(len(s)/2)+1)]
    return  min(short_len) if short_len else 1

Tip.
for- if- else를 zip을 이용하여 간결하게 표기할 수 있다.
