I am developing an application with check the status of a bunch of sensors.
The way to get their status is very straightforward:
sensor_name.get_status()
Instead of writing several calls to check all those sensors, I was wondering if I could store all sensor names in a list of strings and let a for do the work for me.
Pretty much like this:
sensors_list = ['sensor_name_1', 'sensor_name_2', 'sensor_name_3']
for sensor in sensors_list:
#call it :-)
How can I get this done?
How about, instead of keeping the names in the list, you just keep the sensors themselves in the list?
sensors = [sensor_1, sensor_2, sensor3]
for sensor in sensors:
sensor.get_status()
Use locals (I will set sensor_name_1 to the min function just so it is callable):
>>> sensor_name_1 = min # just an example function
>>> locals()['sensor_name_1']([1,2,3])
1
For your specific example, you would do:
sensors_list = ['sensor_name_1', 'sensor_name_2', 'sensor_name_3']
for sensor in sensors
locals()[sensor].get_status()
