WHAT DOES THE .append thing do?
You should really post more meaningful questions, like what language are you using, where have you seen the append function etc. Remember repl.it is a special platform for many languages not just python so be more specific. Now I'm assuming you're using python and the
.append() function is used on list.
Let's suppose you have a list named
l which is basically
[5, 8, 9]. Just suppose, it can be anything.
Now if you do
l.append(7) it becomes
[5, 8, 9, 7].
