The following should be done in a python code editor and should run on your computer's terminal.

1. Your task for this exercise is to generate an amino acid usage report with counts only, and in no particular order. Do this by opening the file below, stripping the lines without amino acid text, and using a dictionary to store each of the 21 amino acids used along with their count as the value. Your output should look like this:

T: 69645 G: 95475 V: 91683 Y: 36836 H: 29255 .....

2. Modify your script from #1 to display only the top 5 most frequently used amino acids and add their percentage use. The output should be like this:

L: 139002 (10.7%) A: 123885 (9.6%) G: 95475 (7.4%) V: 91683 (7.1%) I: 77836 (6.0%)
