It's effectively a 'table' with columns named 'dev', 'input' and
'name' and I want to access the values of the table using the variable
name.

I could, obviously, store the data in a database (sqlite), I have some
similar data in a database already but the above sort of format in
Python source is more human readable and accessible.  I'm just looking
for a less laborious way of entering it really.



Maybe a dict of dicts:

tx = {lv: {'dev':'bbb', 'input':'1', 'name':'Leisure volts'},
  sv: {'dev':'bbb', 'input':'0', 'name':'Starter volts'},
  ...}

Might have one or two advantages.

Neat, I like that, thank you.

How about:

keys = ['abbr', 'dev', 'input', 'name']
adccfg = [
('lv', 'bbb', '1', 'Leisure volts'),
('sv', 'bbb', '0', 'Starter volts'),
('la', 'bbb', '2', 'Leisure Amps'),
('sa', 'bbb', '3', 'Starter Amps'),
('bv', 'adc2', '0', 'BowProp Volts'),
]
adccfg = [dict(zip(keys, row)) for row in adccfg]

or even:

keys = ['abbr', 'dev', 'input', 'name']
adccfg = '''\
lv,bbb,1,Leisure volts
sv,bbb,0,Starter volts
la,bbb,2,Leisure Amps
sa,bbb,3,Starter Amps
bv,adc2,0,BowProp Volts
'''
adccfg = [dict(zip(keys, line.split(','))) for line in adccfg.splitlines()]

Named tuples stored in a dictionary or list?

How to enter multiple, similar, dictionaries?

2023-12-11 Thread Chris Green via Python-list 
Is there a way to abbreviate the following code somehow?

lv = {'dev':'bbb', 'input':'1', 'name':'Leisure volts'}
sv = {'dev':'bbb', 'input':'0', 'name':'Starter volts'}
la = {'dev':'bbb', 'input':'2', 'name':'Leisure Amps'}
sa = {'dev':'bbb', 'input':'3', 'name':'Starter Amps'}
bv = {'dev':'adc2', 'input':0, 'name':'BowProp Volts'}

It's effectively a 'table' with columns named 'dev', 'input' and
'name' and I want to access the values of the table using the variable
name.

I could, obviously, store the data in a database (sqlite), I have some
similar data in a database already but the above sort of format in
Python source is more human readable and accessible.  I'm just looking
for a less laborious way of entering it really.
