my_list = ["banana", "cherry", "apple"]

# len() : get the number of elements in a list
print("Length:", len(my_list))

# append() : adds an element to the end of the list
my_list.append("orange")

# insert() : adds an element at the specified position
my_list.insert(1, "blueberry")
print(my_list)

# pop() : removes and returns the item at the given position, default is the last item
item = my_list.pop()
print("Popped item: ", item)

# remove() : removes an item from the list
my_list.remove("cherry") # Value error if not in the list
print(my_list)

# clear() : removes all items from the list
my_list.clear()
print(my_list)

# reverse() : reverse the items
my_list = ["banana", "cherry", "apple"]
my_list.reverse()
print('Reversed: ', my_list)

# sort() : sort items in ascending order
my_list.sort()
print('Sorted: ', my_list)

# use sorted() to get a new list, and leave the original unaffected.
# sorted() works on any iterable type, not just lists
my_list = ["banana", "cherry", "apple"]
new_list = sorted(my_list)

# create list with repeated elements
list_with_zeros = [0] * 5
print(list_with_zeros)

# concatenation
list_concat = list_with_zeros + my_list
print(list_concat)

# convert string to list
string_to_list = list('Hello')
print(string_to_list)
