Question

I have three lists in python. Let’s say :

list_a
list_b
list_c

Now I am calling a method which also return a list and save into the above lists.
For example:

list_a = get_value(1)
list_b = get_value(2)
list_c = get_value(3)

I think the way I choose to call a same methods with different parameters are not a good option. Would it be possible for us to call these methods within one line?

I am beginner in Python, but what about the tuple option?

Answer 1

A list of lists?

ll = [get_value(x) for x in (1, 2, 3)]

or with your three lists:

list_a, list_b, list_c = [get_value(x) for x in (1, 2, 3)]

taking into account, that get_value cannot be modified and returns just the single list.

Another possibility would be a dictionary.

params = {'a': 1, 'b': 2, 'c': 3}
result = {k:get_value(v) for k,v in params.iteritems()}
# result == {'a': get_value(1), 'b': get_value(2), 'c': get_value(3)}
