adding a variable to a list in python

Question

I am a bit confused about how I can add a variable to a list in python. I have looked at this post

and this was not very helpful. This is the code I have:

lst = [1, 2, 3]
        something = 4
        print(lst.append(something))

This for some reason returns none. Unsure if I am missing something. Any help would be grateful.

Well, that's totally understandable because list.append() always return None and you are actually trying to print what this append() function is returning. — spectre009

Does this answer your question? Why does list.append() return None? — pho

Does this answer your question? Why do these list operations (methods: clear / extend / reverse / append / sort / remove) return None, rather than the resulting list? — Karl Knechtel

lst = [1, 2, 3]
something = 4
res = [int(something)]
print(lst + res)
