如何向用戶詢問循環金額

Question

我正在嘗試創建一個小程序，詢問用戶該班有多少名學生報名，然后用戶輸入金額。 但是之后，我需要運行一個循環來運行用戶指定的學生數量。 到目前為止，這就是我所擁有的。

def class ():
    x = input ("How many students will be entered? ")
    for count in range (x):
      name = input ("What is your name? ")
      major = input ("What is your major? ")
      year = input ("and your year? ")
      print (name, major, year)

Answer 1

難道不是在python中預定義了類嗎？

因此，您不能將函數稱為“類”。 也使用raw_input。

將輸入值轉換為字符串。

 x = int (raw_input ("How many students will be entered? "))

將其定義為如下函數：

def doSomething():
    x = int (raw_input ("How many students will be entered? "))
    for count in range (x):
      name = raw_input ("What is your name? ")
      major = raw_input ("What is your major? ")
      year = raw_input ("and your year? ")
      print (name, major, year)

然后調用它：

doSomething();

Answer 2

您忘了給我們指定您的問題。 但是很明顯，您正在嘗試將由輸入函數返回的str轉換為int類型。

x = int (input ("How many students will be entered? "))
