Exercise: Extracting Toppers From a Student Record

Problem statement

You have been provided with different grades lists which are all lists of dictionaries, containing the name of the student and the grade percent that they achieved. Here’s an example list:

grades = [
   {"name": "Mary","percent": 90},
   {"name": "Don","percent": 55},
   {"name": "Bob","percent": 70},
   {"name": "Jim","percent": 85},
   {"name": "Meg","percent": 80},
   {"name": "Jil","percent": 75}
]

Therefore, your task is to write the get_top() function which takes in this grades list and then extracts only the students with percent values greater than or equal to 80%.

You need to use any of the functional programming built-in functions (map, filter, reduce) or list comprehension to complete this task.

Input

grades = [
   {"name": "Mary","percent": 90},
   {"name": "Don","percent": 55},
   {"name": "Bob","percent": 70},
   {"name": "Jim","percent": 85},
   {"name": "Meg","percent": 80},
   {"name": "Jil","percent": 75}
]

Output

['Mary', 'Jim', 'Meg']
