將與先前的位置

Question

循環的當前位置，這可能是一個愚蠢的問題，但 我有一個循環，其中n是用戶輸入

n = input("enter number"): 
for i in range(n): 
    a = input("enter a value for each n") 

現在我需要與先前添加的當前位置的位置

c = a[n] + a[n-1] 

我該怎麼做？

可以說，N = 5和= 1,2,3,4,5

Answer 1

if you want your script to add numbers, you need to store the sum in a variable 

n = int(input("enter number")) 
b = 0 # store sum here 
for i in range(n): 
    a = int(input("enter a value for each n")) 
    b = b + a 
    print(b) 

enter number4 
enter a value for each n2 
2 
enter a value for each n3 
5 
enter a value for each n4 
9 
enter a value for each n6 
15
