Write a program that reads in a file and counts the number of each letter in the file. Ignore anything that is not a letter and consider both upper case and lower case

You should write your program in a function called count_letters which accepts a single parameter filename.

Example Output

You should print out the frequency of each of the letters seen as follows:

The count of the letters for the file test.txt is:

A: 1

h: 2

i: 7

x: 5

Getting Started

You can copy and paste the following in to get started.

def count_letters(filename):

pass

if __name__ == "__main__":

count_letters("words.txt")

THIS IS WHAT THE TEXT FILE "test.txt" includes:

This is a simple file With a few lines And some odd spacing
