Finding the similarity between two strings, and searching for substrings in larger strings are two regularly occurring problems in computer science. For this problem you will be exploring an example of both. Write a function starting_string(str_one, str_two) that takes in two strings, and returns the common substring that begins each string. If the two strings do not begin with a common substring, return an empty string. For example, given the strings 'Episode II: Attack of the Clones' and 'Episode III: Revenge of the Sith', the starting common substring would be 'Episode II', since it's the longest string which can be found at the start of both strings with a length (10). Hints: • Be sure to avoid index out of range errors in situations where one string is longer than the other.

Python string:-
A string in Python is a collection of Unicode characters. Every character from every language is included in Unicode, which was created to bring encoding standardization. Python Unicode is a resource for learning about Unicode. Strings include things like "hello world" and "LKJH019283," for instance. An associated string is added to a variable in computer programming.
