- python exercise: Write a Python function called get_top_students that takes the list of dictionaries as input and returns a dictionary containing the name and GPA of the top two students in the list. Each dictionary has the following keys: "name", "age", "major", and "gpa".arrow_forward1c) Average sentence length We will create a function ( avg_sentence_len ) to calculate the average sentence length across a piece of text. This function should take text as an input parameter. Within this function: 1. sentences : Use the split() string method to split the input text at every '.'. This will split the text into a list of sentences. Store this in the variable sentences . To keep things simple, we will consider every "." as a sentence separator. (This decision could lead to misleading answers. For example, "Hello Dr. Jacob." is actually a single sentence, but our function will consider this 2 separate sentences). 2. words : Use the split() method to split the input text into a list of separate words, storing this in words . Again, to limit complexity, we will assume that all words are separated by a single space (" "). (So, while "I am going.to see you later" actually has 7 words, since there is no space after the ".", so we will assume the this to contain 6 separate…arrow_forwardMatich the following statements with the correct data structure by clicking on the drop down arrow and selecting the correct choice..

- The mapped list pattern Our second pattern is the mapped list pattern, described in video 4 3 mapped list pattern. Often we need to write a function that takes a list as a parameter and returns a new list in which each item in the original list is "mapped" to a new item in the result list. For example, the following function takes a list of numbers as a parameter and returns a list of all the numbers squared, e.g. squares ( [1, 3, 7]) returns [1, 9, 49]. def squares (nums): "Returns the squares of the given numbers""" result = [] for num in nums: result.append (num * num) return result Although this is just a special case of the accumulator pattern, it is so common that we give it its own name: the mapped list pattern. Consider the following function: def squares(nums): ""Returns the squares of the given numbers""" result = [] for num in nums: result.append (num * num) return result If the main program calls print(squares ( [5, -3, 2, 7]) what is the state table for the function…arrow_forward11111 2) Name: 2.
