HackerRank Re.findall() & Re.finditer() solution in python

HackerRank Re.findall() & Re.finditer() solution in Python – In this Re.findall() & Re.finditer() problem in Python programming, you are given a string S. It consists of alphanumeric characters, spaces and symbols(+,-).

Your task is to find all the substrings of S that contains 2 or more vowels. Also, these substrings must lie in between 2 consonants and should contain vowels only.

_re.findall()

The expression re.findall() returns all the non-overlapping matches of patterns in a string as a list of strings.
_Code

>>> import re
>>> re.findall(r'\w','http://www.hackerrank.com/')
['h', 't', 't', 'p', 'w', 'w', 'w', 'h', 'a', 'c', 'k', 'e', 'r', 'r', 'a', 'n', 'k', 'c', 'o', 'm']

_{re.finditer()}

The expression re.finditer() returns an iterator yielding MatchObject instances over all non-overlapping matches for the re pattern in the string.
