Appending an element in nested list comprehension python

My (derailed) mind would like to do the following:

list1 = [1,2,3]
list2 = ['a','b','c']
list3 = [list([a for a in list2]).append(n) for n in list1]

to output this:

[[‘a’, ‘b’, ‘c’, ‘1’], [‘a’, ‘b’, ‘c’, ‘2’], [‘a’, ‘b’, ‘c’, ‘3’]]

only using single line list comprehensions (yes I’m in blinded by Haskell love).

Instead it outputs a list of 3 None type items which is understandable as I’m getting the output of append 3 times.

I think there’s a key python idea I’m missing here on how I could make this work (or me being completely illogical), any help would be appreciated 🙂

>Solution :

No need to over-complicate things.

>>> list1 = [1,2,3]
>>> list2 = ['a','b','c']
>>> [list2 + [x] for x in list1]
[['a', 'b', 'c', 1], ['a', 'b', 'c', 2], ['a', 'b', 'c', 3]]
