第一题：
import reimport string
inText = raw_input('Please enter a string of text (the bigger the better): ')
outText = inText.lower()
outText = re.sub(r"[^a-z]","", outText)
count, letter = [], []
for l in string.ascii_lowercase:
n = outText.count(l)
if n != 0:
count.append(n)
letter.append(l)
map = sorted(zip(count, letter), key=lambda x:(x[0]), reverse=True)
print 'The distribution of characters in "' + inText + '" is:'
for c in map:
print c[1] * c[0]
