Introduction To Python
Python is a widely-used, interpreted, object-oriented, and high-level programming language with dynamic semantics, used for general-purpose programming. It was created by Guido van Rossum, and first released on February 20, 1991.
Python is a computer programming language often used to build websites and software, automate tasks, and conduct data analysis. It is also used to create various machine learning algorithm, and helps in Artificial Intelligence. Python is a general purpose language, meaning it can be used to create a variety of different programs and isn’t specialized for any specific problems. This versatility, along with its beginner-friendliness, has made it one of the most-used programming languages today. A survey conducted by industry analyst firm RedMonk found that it was the most popular programming language among developers in 2020.

Words Score in Python – HackerRank Solution
Problem:
In this challenge, the task is to debug the existing code to successfully execute all provided test files.
Consider that vowels in the alphabet are a, e, i, o, u and y.
Function score_words takes a list of lowercase words as an argument and returns a score as follows:
The score of a single word is if the word contains an even number of vowels. Otherwise, the score of this word is . The score for the whole list of words is the sum of scores of all words in the list.
Debug the given function score_words such that it returns a correct score.
Your function will be tested on several cases by the locked template code.
Input Format
The input is read by the provided locked code template. In the first line, there is a single integer denoting the number of words. In the second line, there are space-separated lowercase words.
Constraints
- Each word has at most letters and all letters are English lowercase letters
Output Format
The output is produced by the provided and locked code template. It calls function score_words with the list of words read from the input as the argument and prints the returned score to the output.
Sample Input 0
2 hacker book
Sample Output 0
4
Explanation 0
There are two words in the input: hacker and book. The score of the word hacker is because it contains an even number of vowels, i.e. vowels, and the score of book is for the same reason. Thus the total score is .
Sample Input 1
3 programming is awesome
Sample Output 1
4
Explanation 1
There are words in the input: programming, is and awesome. The score of programming is since it contains vowels, an odd number of vowels. The score of is is also because it has an odd number of vowels. The score of awesome is since it contains vowels, an even number of vowels. Thus, the total score is .
