python - 多个 Try-Excepts 后跟 Python 中的 Else

Question

有没有办法让几个连续的 Try-Except 子句仅在所有子句都成功时才触发一个 Else？

举个例子:

 try:
    private.anodization_voltage_meter = Voltmeter(voltage_meter_address.value) #assign voltmeter location
except(visa.VisaIOError): #channel time out
    private.logger.warning('Volt Meter is not on or not on this channel')
try:
    private.anodization_current_meter = Voltmeter(current_meter_address.value) #assign voltmeter as current meter location
except(visa.VisaIOError): #channel time out
    private.logger.warning('Ammeter is not on or not on this channel')
try:
    private.sample_thermometer = Voltmeter(sample_thermometer_address.value)#assign voltmeter as thermomter location for sample.
except(visa.VisaIOError): #channel time out
    private.logger.warning('Sample Thermometer is not on or not on this channel')
try:
    private.heater_thermometer = Voltmeter(heater_thermometer_address.value)#assign voltmeter as thermomter location for heater.
except(visa.VisaIOError): #channel time out
    private.logger.warning('Heater Thermometer is not on or not on this channel')
else:
    private.logger.info('Meters initialized')

如您所见，如果所有仪表都关闭，您只想打印 meters initialized，但正如目前所写，它仅取决于加热器温度计。有什么方法可以堆叠这些吗？

就我个人而言，我只需要一个行程变量 init_ok 或类似的东西。

将其设置为True，并将所有except子句设置为False，然后在最后测试？
