使用ConfigParser不支持的操作数类型

我正在尝试制作一个游戏,每次玩游戏时,都会从ini文件中的值中扣除玩家.5。但是我一直收到错误,我不知道该怎么做。这是我的代码。不要担心评论,这些是给我的,我稍后关闭while循环。这只是代码的一部分。顺便说一句,代码工作,只是没有。感谢。

def rerun():
import ConfigParser
from ConfigParser import ConfigParser

parser = ConfigParser()
parser.read('Game.ini')

PlrMny = parser.get('money_value', 'Amount')
#config = ConfigParser.ConfigParser()
configFile = open("C:\Python27\Game.ini", "w")
#config.read(configFile)
#valueamount = config.getfloat("section","starting_value")
print PlrMny

print "You will be given a $10 starting amount. Each game costs $.50 to play and is 
deducted when you input the first value."
print "\nGetting one match gives $1 and the output is multiplied by 2 for each extra 
match."
print "\nCurrent Amount =",PlrMny,

def gamble():

    import random
    import sys
    number1 = random.randint (1, 20)
    number2 = random.randint (1, 20)
    number3 = random.randint (1, 20)
    number4 = random.randint (1, 20)
    number5 = random.randint (1, 20)



    def input():
        c = 0
        PlrMny == type(int)
        print "\n\n\n\nTry guess what five numbers the computer will guess. Type '100' 
        in any of the inputs to close program prematurely"    
        print "Money =",PlrMny,
        #parser.set("money_value", "Amount",10000)
        #parser.write ('Game.ini')

        while True:
            try:
                User11 = int(raw_input( "\n\nNumber 1 : "))
                parser.set('money_value','Amount',PlrMny - .5)
                parser.write (configFile)
                if User11 < 1:
                    print "Error"
                elif User11 == 100:
                    sys.exit()
                elif User11 > 20:
                    print "Error"
                else:
                    break
            except ValueError:
                print "Error"

这是错误:

    Traceback (most recent call last):
  File "C:\Python27\Gamb Game.py", line 181, in <module>
    rerun()
  File "C:\Python27\Gamb Game.py", line 180, in rerun
    gamble()
  File "C:\Python27\Gamb Game.py", line 174, in gamble
    input()
  File "C:\Python27\Gamb Game.py", line 42, in input
    parser.set('money_value','Amount',PlrMny - .5)
    TypeError: unsupported operand type(s) for -: 'str' and 'float'

帮助?

您试图从字符串中减去.5,而不是浮点数。也就是说,你的变量PlrMny是一个字符串。

替换

parser.set('money_value','Amount',PlrMny - .5)

parser.set('money_value','Amount',str(float(PlrMny) - .5)) #if you want money_value to be a string

但是,使用parser.set不会更改正在运行的程序中PlrMny的值。它只会更改.ini文件上下文中的值。所以,你可能想要做的就是使用这段代码:

PlrMny = float(PlrMny) - .5
parser.set('money_value','Amount',str(PlrMny))

在写入ini时,您需要将PlrMny强制转换为字符串,以避免在读取ini文件时出错。
