Re.findall() & Re.finditer() HackerRank Solution In Python

Problem

_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.

Code

>>> import re>>> re.finditer(r'\w','http://www.hackerrank.com/')<callable-iterator object at 0x0266C790>>>> map(lambda x: x.group(),re.finditer(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']

Task

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.

Note :
Vowels are defined as: AEIOU and aeiou.
Consonants are defined as: QWRTYPSDFGHJKLZXCVBNM and qwrtypsdfghjklzxcvbnm.

Input Format

A single line of input containing string S.

Constraints

0 < len(S) < 100

Output Format

Print the matched substrings in their order of occurrence on separate lines.
If no match is found, print -1.

Sample Input

rabcdeefgyYhFjkIoomnpOeorteeeeet

Sample Output

eeIooOeoeeeee

Explanation

ee is located between consonant d and f.
Ioo is located between consonant k and m.
Oeo is located between consonant p and r.
eeeee is located between consonant t and t.
