數字和用戶輸入的乘積之和

Question

如何使該程序正常工作？

問題

我需要設置用戶可以輸入多少個浮點輸入。 然后，將每個輸入乘以一個數字，並對每個乘積求和。

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)

輸出應如下所示：

輸入您想輸入多少個數字？ 3

數字1的值是多少？ 2

數字2的值是多少？ 3

3的值是多少？ 1個

輸入被乘數：5

總價值是：30

Answer 1

您可以這樣操作：

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

這應該解決您的問題：

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))
