Python实现计算字符串中出现次数最多的字符示例

ee = 'aa111(((bbhhhhhh%jjjjjj%(ccc((vvvv22'
cc='11222333'
def max_letter_count(n):
  list4 = []
  list1 = []
  list2 = []
  for i in n:
    list3 = []
    count_max = n.count(i)
    list3.append(i)
    list3.append(count_max)
    list1.append(list3)
    list2.append(count_max)
  num=max(list2)
  for i in range(len(list2)):
    if list2[i] == num:
      list4.append(list1[i][0])
  return list(set(list4)),'字符出现最大次数为:%d' % num
print(max_letter_count(ee))

ee = 'aa111(((bbb((%%%%%%%%%%%(ccc((vvvv22'
cc='11222333'
def num(n):
  return max(n,key=n.count)
print(num(cc))

print(num(ee))
