我最近一直在研究 Squish 测试脚本，并尝试做一些类似于解决方案中描述的事情： Python 进程使用的总内存？
我的代码中的相关片段如下：
def measureMemory():
w = wmi.WMI('.')
result = w.query("SELECT WorkingSet FROM Win32_PerfRawData_PerfProc_Process WHERE Name=\"some_program\"")
print result
for WorkingSet in result:
print WorkingSet
subset = result[0]
print subset['WorkingSet']
# return result[0]['WorkingSet']
for i in range(50):
memory = measureMemory()
if memory:
# test.passes("%d memory used during undo." % memory)
print memory
不幸的是，每当我实际尝试运行该东西时，我都会遇到错误，如下所示。
[<_wmi_object: \\USER-PC\root\cimv2:Win32_PerfRawData_PerfProc_Process.Name="some_program">]
instance of Win32_PerfRawData_PerfProc_Process
{
Name = "some_program";
WorkingSet = "19386368";
};
Traceback (most recent call last):
File "C:\Python26\Test scripts\Testify", line 25, in -toplevel-
memory = measureMemory()
File "C:\Python26\Test scripts\Testify", line 19, in measureMemory
print subset['WorkingSet']
File "C:\Python24\Lib\site-packages\win32com\client\dynamic.py", line 242, in __getitem__
raise TypeError("This object does not support enumeration")
TypeError: This object does not support enumeration
我不确定为什么这应该引发错误，因为我认为我没有从我获取代码的示例中改变任何重要的内容。我正在使用 Python 2.4.4，如果这很重要的话，不幸的是我无法真正升级，无论它有多大帮助。
