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):

帮助?
答案 0 :(得分:1)
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
行parser.set('money_value','Amount',PlrMny - .5)
带
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。
