在Python中除了COMError

在python中除了COMError之外有困难。下面是我打算在AutoCAD中做一些事情的方法。

    def populate_drawing(self):
        nMeasurementsFinal = Feature_recognition.determine_OD_dims(Feature_recognition(), "C:\\Users\\buntroh\\Documents\\Rotoworks\\122508.csv")
        while True:
            try:
                for nObject in self.acad.iter_objects(None, None, None, False):
                    if hasattr(nObject, 'TextString'):
                        try:
                            nObject.TextString = nMeasurementsFinal[nObject.TextString]
                        except KeyError as e:
                            continue
            except COMError:
                self.acad.doc.SendCommand("Chr(3)")
            break

COMError异常是因为无论何时在运行脚本之前在AutoCAD中选择了某些内容,它都会返回COMError。然而,即使有例外,我仍然得到:

COMError: (-2147418111, 'Call was rejected by callee.', (None, None, None, 0, None))

当没有选择任何内容并且脚本不应该处理COMError异常时,我得到:

NameError: global name 'COMError' is not defined

不确定该怎么做。我导入了 comtypes ,所以我不确定为什么COMError未定义。

同意以上评论之一,您需要

from comtypes import COMError

然后,您的异常可能是这样的,并假设出现错误: COMError:(-2147418111,'通话被被叫方拒绝。',(无,无,无,0,无))

except COMError as ce:
    target_error = ce.args # this is a tuple
    if target_error[1] == 'Call was rejected by callee.':
        self.acad.doc.SendCommand("Chr(3)")
