I have a dictionary as follows:-
{
u'StarterAmps1': Row(id=4, ain=u'AIN3', name=u'StarterAmps1',
conv=6834.374834509803, Description=u'Starter Amps'),
u'LeisureVolts': Row(id=1, ain=u'AIN0', name=u'LeisureVolts',
conv=29.01374215995874, Description=u'Leisure Volts'),
u'RudderPos': Row(id=6, ain=u'AIN5', name=u'RudderPos', conv=0.028125,
Description=u'Rudder Position'),
u'xx': Row(id=7, ain=u'AIN6', name=u'xx', conv=0.028125, Description=u''),
u'LeisureAmps1': Row(id=3, ain=u'AIN2', name=u'LeisureAmps1',
conv=32.727273081945, Description=u'Leisure Amps'),
u'StarterVolts': Row(id=2, ain=u'AIN1', name=u'StarterVolts',
conv=28.94469628911757, Description=u'Starter Volts')
}
I want to output a menu to a user comprising some parts of the
dictionary (ain and Description) sorted by ain.
Is there some incantation of sorted() that will do what I want? I
can't quite fathom out the 'key=' parameter needed to sort it by the
tuple item. Maybe I need a cmp= ?
E.g. I want to do something like:-
for meas in sorted(adc.cfg, key=???):
print(adc.cfg[meas].ain, adc.cfg[meas].Description)
What's needed in the ???
