The problem is from codeforces: http://www.codeforces.com/problemset/problem/118/A
Python is good at string manipulations. The problem is easy and the solution is straightforward. Just read the problem statement carefully… I didn’t do so that is why I failed the first submission because I think ‘Y’ is a consonant which is not.
v = ['a', 'e', 'i', 'o', 'u', 'y', 'A', 'E', 'I', 'O', 'U', 'Y']
s = raw_input()
r = ''
for i in s:
if any(i in y for y in v):
pass
else:
r += '.' + i.lower()
print r
