數字和用戶輸入的和產品的總和

Question

如何使該程序起作用？

問題

我需要設置多少浮數輸入用戶可以進入。然後將每個輸入乘以一個數字並對每個產品進行求和。

代碼

userInput = int(input("Enter how many numbers you would like to input? ")) 
numList = [None] * userInput 
for x in range(userInput): 
    numList[x] = float(input("What is the value of number 1? ")) 
multiplicand = int(input("Enter the multiplicand: ")) 
for y in numList: 
product = multiplicand * y 
sumOfproduct = sum(product) 
print(sumOfproduct) 

輸出應該像這樣：

回車多少個號碼，你想輸入？ 3

數字1的值是多少？ 2

2號的價值是什麼？ 3

3號的值是多少？ 1

輸入被乘數：5

的總價值爲：30

Answer 1

你可以這樣來做：

userInput = int(input("Enter how many numbers you would like to input? ")) 
multiplicand = int(input("Enter the multiplicand: ")) 
ans = 0 
for x in range(userInput): 
    num = float(input("What is the value of number " + str(x) + " ? ")) 
    ans += num*multiplicand 

print(ans) 

Answer 2

userInput = int(input("Enter how many numbers you would like to input? ")) 
numList = [None] * userInput 
for x in range(userInput): 
    numList[x] = float(input("What is the value of number "+str(x+1)+"?")) 
multiplicand = int(input("Enter the multiplicand: ")) 
l = sum(numList)*multiplicand 
print (l) 

Answer 3

這應該解決烏爾概率： `

temp1 = 1 
temp2 = 0 
user_input=[] 
no_of_input=int(input("Enter how many numbers you would like to input? ")) 

for i in range(0,no_of_input) : 
    num=float(input("enter input {0}".format(i+1))) 
    user_input.append(num) 

multiplicand=float(input(("enter the multiplicand"))) 



for j in range(0,no_of_input) : 
    temp1=multiplicand * user_input[j] 
    temp2= temp2 + temp1 



print("total value is {0}".format(temp2))
