python 输出列表，7的倍数。

a,b=list(map(int,input().split()))
list=[]
count=0
for i in range(a,b+1):
  if i%7==0 and i%10!=7:
    list.append(i)
    count+=1
if count==0:
  print("-1")
else:
  print(list)

count = 0
sz = []
num = 0
a = input("请输入一个整数：")
a = int(a)
n = input("请输入一个整数：")
n = int(n)

while a < n:
    a += 1
    if a%7 == 0:
        sz.append(a)
        count += 1
        print("7的倍数是:",a)

for i in range(len(sz)):
    num += sz[i]
print("100之内有%s个奇数，全部奇数的和是%s"%(count,num))
