s = input()
cnt = 0
s = list(s)
s.sort()
ss = set(s)

for i in ss:
    if s.count(i) > cnt:
        cnt = s.count(i)
for i in ss:
    if s.count(i) == cnt:
        print(i, end="")

更改

s = input()
cnt = 0
s = list(s)
s.sort()
ss = set(s)

for i in ss:
    a = s.count(i)
    if a > cnt:
        cnt = a
for i in ss:
    if s.count(i) == cnt:
        print(i, end="")

原因：

多一个s.count()也会使运行时间变多，所以应该减少s.count的使用
