join() function can be used to either join lists or strings with a common string.
The basic format for using this function:
(1) Joining lists:
We can all the list elements with a common character. Let's say that we have a list with the first 5 English alphabets and let's say that we want to join these elements with a underscore.
>>> alphabets = ['a','b','c','d','e']
(2) Joining strings:
We can use this same formatting to join the strings.
>>> string = 'abc'
