with open("the.txt") as ecoli:

from collections import defaultdict

counts = defaultdict(int)

for line in ecoli:

if line.startswith(">"):

continue

for char in line:

if char in {"A", "C", "D", "E", "F", "G", "H", "I", "K", "L", "M", "N", "P", "Q", "R", "S", "T", "V", "W", "Y"}:

counts[char] += 1

total = float(sum(counts.values()))

for key,val in counts:

print ("{}: {}, ({:.1%})".format(key,val, val / total))

Can someone please expain to me how would you go about taking the results (below) and orgazing them in terms of percentage??? As in, I want the highest percetage on the top and lowest on the bottom.

THANKS
