n=int(input())
a=[]
for i in range(n):
    fenshu=float(input())
    a.append(fenshu)
a.pop(0)
a.pop()

求平均数：

sum = 0
for i in range(a.size):
    sum += a[i];
print(sum / a.size)

@continue_and_break

a=int(input())
b=input().split()
for i in range(a):
    b[i]=int(b[i])
b.sort()
b.pop(0)
b.pop(a-2)
c=0
for i in range(a-2):
    c+=int(b[i])
c=c/(a-2)
print("%.2f"%c)

这应该可以
