非整數破整數輸入

Question

當我在此代碼它與此消息打破進入非數：

Traceback (most recent call last): File "C:/Users/Default/Desktop/AS91076.py", line 12, in temp = int(input("At what Temperature do you want your wash? (Maximum 40 Degrees)")) ValueError: invalid literal for int() with base 10: 'asdf'

 temp = int(input("At what Temperature do you want your wash? (Maximum 40 Degrees)")) 
     if temp < 41: 
     **Misc Code** 
     else: 
      print("Not a valid Temperature!") 

Answer 1

的任意字符串不能被轉換爲數字。如果您希望在用戶鍵入非整數時捕捉案例，則可以使用try語句。

try: 
    temp = int(input("At what Temperature do you want your wash? (Maximum 40 Degrees)")) 
    if temp < 41: 
     **Misc Code** 
    else: 
     print("Temperature too high!") 
except ValueError as e: 
     print("Not a valid Temperature!")
