methods are used to manipulate data

listname.append("item")
use + to create a new list based off another one:
new_list = listname + ["item1", "item"2]
add an item to s specific place in a list:
listname[i] = "newitem"
([i] is the number index: [0] is first, [-1] is last)
if 2D list listname[i][i]
remove the first occurrence of an element:
listname.remove("element")
tuples are immutable lists
