Due to its key$-$value pair format, dictionaries can be used to present some forms of structured data in an easily readable way. This challenge will help you write code to present frequency data for characters in strings.

Due to its key$-$value pair format, dictionaries can be used to present some forms of structured data in an easily readable way. This challenge will help you write code to present frequency data for characters in strings. Dictionaries are very good data structures for organizing data in a readable format. Your aim is to write a function called word$\_$counter, which will take in a line of text and output a dictionary with each letter as a key, the value being the frequency of appearance of the letter. Here are some hints to help you out: $$ Treat different uppercase and lowercase letters separately. For example, M and m should have different counts. $$ Drop empty spaces. $$ Assume that sentences will not have any special characters.
