非整数破整数输入

Question

当我在此代码它与此消息打破进入非数：

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转换为数字。如果您希望在用户键入非整数时捕捉案例，则可以使用try语句。

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!")
