append(): append the object to the end of the list.
insert(): inserts the object before the given index.
extend(): extends the list by appending elements from the iterable.
List Concatenation: We can use + operator to concatenate multiple lists and create a new list.
#append to list
lst = [1, 2, 3]
li = 4
lst.append(li)
#lst is now [1, 2, 3, 4]
.append("the add"): append the object to the end of the list.
.insert("the add"): inserts the object before the given index.
.extend("the add"): extends the list by appending elements from the iterable.food = "banana"
basket = []
basket.append(food)
test_list = [['abc','2'], ['cds','333'], ['efg']]
test_list[2].append('444')
# test_list is now: [['abc','2'], ['cds','333'], ['efg', '444']]
