Python中处理负整数的问题

Question

我正在尝试检查一些条件的输入，然后将字符串转换为整数，在此之后我想确保整数不是负数，否则提示用户再次输入。

它适用于字符串条件，但是当我输入负数时，输入会引发错误“输入预计最多 1 个参数，得到 2”

关于如何评估这一点的任何想法？

     #This compares whether the bet placed is greater than the value in the players chip_balance. It prompts the player for a lower bet if it is of greater value than chip_balance

 while bet > chip_balance:

      print('Sorry, you may only bet what you have 0 -', chip_balance)

      bet = input("Place your bet: ")

      while bet == '':

          bet = input("Can't be an empty bet please try again ")

      while bet.isalpha() or bet == '':

          bet = input("Must be a numerical value entered \n \n Place You're bet:")

      bet = int(bet)

 if bet < 0:

      bet = input("Sorry, you may only bet what you have sir! 0 \-", chip_balance)

      bet = int(bet)

Answer 1

bet&nbsp;=&nbsp;input("Sorry,&nbsp;you&nbsp;may&nbsp;only&nbsp;bet&nbsp;what&nbsp;you&nbsp;have&nbsp;sir!&nbsp;0&nbsp;\-",&nbsp;chip_balance)input 函数不接受 2 个参数，而 print 接受。你可以这样做；bet&nbsp;=&nbsp;input("Sorry,&nbsp;you&nbsp;may&nbsp;only&nbsp;bet&nbsp;what&nbsp;you&nbsp;have&nbsp;sir!&nbsp;0&nbsp;\-&nbsp;{}".format(chip_balance))
