while True:
   try:
       list1 = list(map(int,input().split()))
       a = list1[0]
       sum = 0
       for i in range(1,len(list1)):
          if(list1[i]<a):
              sum = sum + list1[i]
       print (sum)
   except:
       break

这个代码，把数组第一个元素先存到a 里面，没问题，通过率100%

while True:
   try:
       list1 = list(map(int,input().split()))
       sum = 0
#a = list1[0]
       for i in range(1,len(list1)):
          if(list1[i]<list1[0]):
              sum = sum + list1[i]
       print (sum)
   except:
       break

但是我不传到a 里面，直接用list1进行if语句判断，通过率只有28%
