我用 python 写了一个简单的脚本。这是一款会说话的电池监视器，灵感来自 IronMan Jarvis。现在的问题是，代码运行完美，但当代码运行时 RAM 不断变满。最后，当 RAM 变满时，PC 崩溃了。可能是什么问题呢？我不使用任何新变量。我通过轮询更新相同的变量。这是我的代码-

# Get power status of the system using ctypes to call GetSystemPowerStatus

import ctypes
from ctypes import wintypes
import speech

def startmonitor():   
    class SYSTEM_POWER_STATUS(ctypes.Structure):
        _fields_ = [
                    ('ACLineStatus', wintypes.BYTE),
                    ('BatteryFlag', wintypes.BYTE),
                    ('BatteryLifePercent', wintypes.BYTE),
                    ('Reserved1', wintypes.BYTE),
                    ('BatteryLifeTime', wintypes.DWORD),
                    ('BatteryFullLifeTime', wintypes.DWORD),
                   ]
    SYSTEM_POWER_STATUS_P = ctypes.POINTER(SYSTEM_POWER_STATUS)
    GetSystemPowerStatus = ctypes.windll.kernel32.GetSystemPowerStatus
    GetSystemPowerStatus.argtypes = [SYSTEM_POWER_STATUS_P]
    GetSystemPowerStatus.restype = wintypes.BOOL

    status = SYSTEM_POWER_STATUS() #define an object of the class SYSTEM_POWER_STATUS
    if not GetSystemPowerStatus(ctypes.pointer(status)):
        raise ctypes.WinError()
    return status
x=0  #counting variable
def setflag0():
    for x in range(7):
        flag[x]=0
    return flag

def setxval():

    if(status.BatteryLifePercent==100):

在循环中的某个地方，一个函数正在使用内存。

可能是系统调用 SYSTEM_POWER_STATUS 正在使用内存。是否可以打电话

status=startmonitor()

在while循环之前？

否则开始删除代码（即使它暂时破坏了功能）以找出哪个部分使用内存并尝试为该部分找到替代方案。
