簡單的Python代碼錯誤

Question

error: Can't convert int to str implicitely 

代碼：

user_name = input("What is your name? ") 
print("Hello {}!, this program is going to ask you to type in a series of numbers (all positive integers)" .format(user_name)) 

total_numbers = input("How many numbers would you like to add") 

for i in range(1, total_numbers): 
    number = float(input("State a numbers {}: " .format(i))) 
    total_numbers += number 

    print("Total number: {}" .format(total_numbers)) 

我的任務是：詢問用戶名輸入。它應該存儲在一個合適的變量中（如user_name） 詢問將輸入多少個數字。將其存儲在適當的變量中。 （如「num_values」） 然後獲取輸入的每個數字。 你需要有保持總全都在結尾處的數字和一些辦法，一旦所有的數字已輸入，你需要打印出像..

Answer 1

的問題是線 -

total_numbers = input("How many numbers would you like to add") 
for i in range(1, total_numbers): 
    number = float(input("State a numbers {}: " .format(i))) 
    total_numbers += number 

你必須total_numbers轉換爲int在range功能使用。像 -

total_numbers = int(input("How many numbers would you like to add")) 
for i in range(1, total_numbers): 
    number = float(input("State a numbers {}: " .format(i))) 
    total_numbers += number 

另外，我看到你將這些數字相total_numbers循環本身裏面，也許你不是要創建一個新的變量，其中0用來初始化並添加它來代替，增加total_numbers本身會給你意外的結果。

代碼將是 -

total_numbers = int(input("How many numbers would you like to add")) 
total = 0.0 
for i in range(1, total_numbers): 
    number = float(input("State a numbers {}: " .format(i))) 
    total += number 
print("Total number: {}" .format(total))
