對于以下問題：編寫一個程序，重復提示用戶輸入整數，直到用戶輸入done。輸入“完成”后，打印出最大和最小的數字。如果用戶輸入的不是有效數字，則使用 try/except 捕獲它并發出適當的消息并忽略該數字。輸入個案：輸入 7、2、bob、10 和 4 并匹配下面的輸出。我的程序沒有正確顯示答案。這里有什么問題？while True:inp = input("Enter number: ")if inp == "done": print("done") breaktry: inp_data = int(inp)except: print("Invalid input")if smallest is None: smallest = inp_dataelif inp_data < smallest: smallest = inp_dataelif inp_data > largest: largest = inp_data print("largest", largest)print("smallest", smallest)輸出：無效輸入，最大值為 10，最小值為 2。

您在打印輸出時遺漏了一些語句。
以下代碼對我有用。
largest = None
smallest = None
while True:
num = input("Enter a number: ")
if num == "done":
break
try:
#print(num)
num = int(num)
if largest is None or largest < num:
largest = num
elif smallest is None or smallest > num :
smallest = num
except ValueError:
print("Invalid input")
continue
print("Maximum is", largest)
print("Minimum is", smallest)
已驗證并成功運行。

largest = None

while True:
num = input("Enter a number: ")
if num == "done":
break
try:
num = int(num)
except:
print("Invalid input")
continue
if largest==None or num > largest:
largest = num
elif smallest==None or smallest > num:
smallest = num
print("Maximum is", largest)
print("Minimum is", smallest)

如果包含 elif 語句，則如果 if 語句中的條件為真，則不會檢查它們，因此如果我有“elif smallest...”，則永遠不會檢查結果為“Minimus is none”。
largest = None
smallest = None
while True:
enter_num = input('Enter a number ')
if enter_num == 'done':
break
try:
num = int(enter_num)
if largest is None or largest < num:
largest = num
if smallest is None or smallest > num:
smallest = num
except:
print('Invalid input')
continue
print('Maximum is', largest)
print('Minimum is', smallest)

試試這個代碼，稍后謝謝我
largest = None
smallest = None
while True:
val = input("Enter a number: ")
if val == "done":
break
try:
val = int(val)
if largest is None or val > largest:
largest = val
elif smallest is None or smallest > val:
smallest = val
except:
print("Invalid input")
continue
print("Maximum is", largest)
print("Minimum is", smallest)

largest = 0
smallest = 100
while True:
num = input('Enter a number: ')
if num == 'done' :
break
try:
l1 = int(num)
except:
print('Invalid Input')
continue
#print(l1)
if l1 > largest:
l2 = l1
largest = l2
elif l1 < smallest:
l3 = l1
smallest = l3
print('Maximum', largest)
print('Minimum', smallest)
這是我唯一能解決的問題。無法弄清楚如何將最大和最小值保持為 none
