Hello Programmers, In this post, you will know how to solve the Finding the percentage in Python HackerRank Solution. This problem is a part of the HackerRank Python Programming Series.
One more thing to add, don’t directly look for the solutions, first try to solve the problems of Hackerrank by yourself. If you find any difficulty after trying several times, then you can look for solutions.
Finding the percentage in Python HackerRank Solution
Problem
The provided code stub will read in a dictionary containing key/value pairs of name:[marks] for a list of students. Print the average of the marks array for the student name provided, showing 2 places after the decimal.
Example
marks key:value pair are
‘alpha’:[20,30,40]
‘beta’:[30,50,70]
query_name = ‘beta’
The query_name is ‘beta’. beta’s average score is (30+50+70)/3=50.0.

The first line contains the integer n, the number of students’ records. The next n lines contain the names and marks obtained by a student, each value separated by a space. The final line contains query_name, the name of a student to query.
Constraints
- 2 <= N <= 10
- 0 <= Marks <= 100
- Length of marks arrays = 3
