Sorting a list by the last character

I'm trying to create a program that would order a list by the last character.

["Apple", "Mellon", "Banana"]

This is my list and I need to arrange them such that it becomes. 

["Banana", "Apple", "Mellon"]

You can sort using a function, here we use the lambda function which looks at the last index of the strings inside of your list.

lst = ["Apple", "Mellon", "Banana"]
sorted(lst, key=lambda x: x[-1])

['Banana', 'Apple', 'Mellon']

Without making a copy of the list you can apply the .sort(). This is a more memory efficient method.

lst.sort(key=lambda x: x[-1])
print(lst)

['Banana', 'Apple', 'Mellon']

You can use sort method by passing a lambda expression for key property.

This method does not return any value but it changes from the original list.

l = ["Apple", "Mellon", "Banana"]
l.sort(key = lambda item: item[-1])

Output

['Banana', 'Apple', 'Mellon']
