Pythonic Programming Tips for Software Engineers

# Problem statement

Given text as a string, use the `Counter` class to find and report the three most frequent letters in that text as three space-separated characters. Treat the letters in a case-independent way. 

# Task
Use the `Counter` class to print a list of the three most frequent letters in a human-readable way (separated by three spaces). Note that only letters should be counted, not other symbols!

## Example
For the text, `"Mary had a little lamb"`, the program should report `"a l m"`.


Discover the most frequently used letters in a text.
