Filter a list by marks using python list comprehension

In this sample, we will try to filter a list of students based on marks, name or id. List comprehension is a simple way to filter a list in Python. Filter can be applied on single or multi dimensional lists.

This sample has a list of 5 students. Each item in the list is another list with student id, name and marks. To apply the filter, we can access these values using positional parameters.

from datetime import datetime #Id, Name, Total Marks studentsList = [ [1, 'Carl', 450], [2, 'Tim', 470], [3, 'Peter', 430], [4, 'George', 425], [5, 'Kim', 480] ] #Filter by marks filteredList = [ [ st[0], st[1], st[2] ] for st in studentsList if st[2] > 450] print("Filter based on Marks: " + str(filteredList)) #Filter by id filteredList = [ st for st in studentsList if st[0] < 3] print("Filter based on Id: " + str(filteredList)) #Filter by name filteredList = [ st for st in studentsList if ('e' in st[1].lower())] print("Filter based on Name: " + str(filteredList))
Output: Filter based on Marks: [[2, 'Tim', 470], [5, 'Kim', 480]] Filter based on Id: [[1, 'Carl', 450], [2, 'Tim', 470]] Filter based on Name: [[3, 'Peter', 430], [4, 'George', 425]]
