统计年龄人数Python

统计年龄人数
从键盘输入一组年龄存入列表中，统计35岁(含35岁）以下年龄段、35岁到59（含59岁）年
龄段和60岁以上年龄段的人数，并输出。
输入格式：输入一行以空格分隔的年龄值。
输出格式：输出各年龄段人数，参看输入输出示例。
输入样例：12 67 55 70 45 40
输出样例：less than and equal 35:1
35 to 60:3
bigger than and equal 60:2

count1 =0
count2 =0
count3 =0
lst = list(map(int, input().split()))
for i in lst:
    if i>=0 and i<=35:
        count1+=1
    elif i>=35 and i<=60:
        count2+=1
    else:
        count3+=1
print('less than and equal 35:{}\n35 to 60:{}\nbigger than and equal 60:{}'.format(count1,count2,count3))

dic = {}

s = ['less than and equal 35','35 to 60','bigger than and equal 60']

n = list(map(int, input('输入一行以空格分隔的年龄值：').split()))

for i in n:
        if i<=35:
                dic[s[0]] = dic.get(s[0],0)+1
        elif 35<i<=59:
                dic[s[1]] = dic.get(s[1],0)+1
        else:
                dic[s[2]] = dic.get(s[2],0)+1

for i in s:
        print(':'.join([i,str(dic[i])]))

连提个问题都要杀人诛心吗（35岁）
