When using a list comprehension, is the order of the new list guaranteed in any way? As a contrived example, is the following behavior guaranteed by the definition of a list

    It has been a while, but since I came up with a similar question myself recently, and needed a bit more explanation to understand what this comes down to exactly, I'll add my two cents, may it help someone else in the future! :) More specifically this is about the order of values resulting from a list comprehension operation.


    Imagine you have the following list:

    list_of_c = [a, b, c, d, e]
    

    I want to round the variables in that list using the following list comprehension:

    list_of_d = [round(value, 4) for value in list_of_c]
    

    My question was whether this would mean that the order resulting from the list comprehension would be the following:

    list_of_d = [round_a, round_b, round_c, round_d, round_e]
    

    And the answer I received very kindly from @juanpa.arrivillaga , was that indeeded, YES that was the case!
