Finding The Percentage - Hacker Rank Solution
Hello coders, today we are going to solve Python Finding The Percentage Hacker Rank Solution.
Task
The provided code stub 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 pairs 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.

Constrains
- 2 ≤ n ≤ 10
- 0 ≤ marks[i] ≤ 100
- length of the marks array = 3
Output Format
Print one line: The average of the marks obtained by the particular student correct to 2 decimal places.
