尋找最小編號

Question

我試圖找到最少的數字，您可以輸入儘可能多的數字，當您輸入-1時，它會中斷。

a=int(input("What is your number of choice? ")) 
b=int(input("What is your number of choice? ")) 
c=int(input("What is your number of choice? ")) 
d=int(input("What is your number of choice? ")) 
smallest=a 

if (b < smallest): 
    smallest=b 
    while(True): 
    smallest =int(input("What is your number of choice? ")) 

    if (smallest == -1): 
     break 
if (c < smallest): 
    smallest=c 
    while(True): 
    smallest =int(input("What is your number of choice? ")) 

    if (smallest == -1): 
     break 
if (d < smallest): 
    smallest=d 
    while(True): 
    smallest =int(input("What is your number of choice? ")) 

    if (smallest == -1): 
     break 
print(smallest, " is smallest of the numbers you chose") 

我找不出如何解決它。

Answer 1

您需要設置一個循環以允許用戶輸入多個值。跟蹤這些值可以用列表來完成，每個輸入追加到它，如下所示：

all_inputs = [] 
val = int(input('Enter a number (or -1 to finish):')) 

while val != -1: 
    all_inputs.append(val) 
    val = int(input('Enter a number (or -1 to finish):')) 

print(str(min(all_inputs)) + ' is the smallest of your numbers') 

min可以有效地找到最小輸入值。

Answer 2

如果c小於b和b比a小你永遠不會因爲你進入以前，而bucle達到c<smallest代碼。

此外您還需要正確縮進您的代碼。

if (b < smallest): 
    smallest=b 
    while(True): 
     smallest =int(input("What is your number of choice? ")) 

     if (smallest == -1): 
      break 

最後中斷退出方法不執行las打印行。
