Question
In Python use the Design Recipe to write a function count_evens_NxN, that consumes a nested list representing a matrix of size NxN. The function should return the number of even numbers in the matrix. For this function, 0 is considered an even number. Include a Docstring!
Note: You may assume the list argument passed to the function is a nested list of integers
Write 3 assert_equal statements to test your function

- In pythonarrow_forwardJS Write a function named count_in_range that takes a list/array of decimal numbers as a parameter. The function must return the number of entries in the parameter whose value is between 16.67 and 47.61. Your count should NOT include any entries whose value is equal to 16.67 or 47.61.arrow_forwardThe function list_combination takes two lists as arguments, list_one and list_two. Return from the function the combination of both lists - that is, a single list such that it alternately takes elements from both lists starting from list_one. You can assume that both list_one and list_two will be of equal lengths. As an example if list_one = [1,3,5] and if list_two = [2,4,6]. The function must return [1,2,3,4,5,6].arrow_forward
- program7.pyThis assignment requires the main function and a custom value-returning function. The value-returning function takes a list of random integers as its only argument and returns a smaller list of only the elements that end with 7. This value-returning function must use a list comprehension to create this smaller list.In the main function, code these steps in this sequence: Set random seed to 42 import randomrandom.seed(42) create an empty list that will the hold random integers. use a loop to add 50 random integers to the list. All integers should be between 200 and 250, inclusive. Duplicates are okay. sort the list in ascending order and then use another loop to display all 50 sorted integers on one line separated by spaces. print a slice showing list elements indexed 5 through 10, inclusive. print a second slice showing the final 5 elements in the sorted list. execute the custom function with the entire original list as its sole argument. report the number of elements in…arrow_forwardPYTHON Problem Statement Given a list of numbers (nums), for each element in nums, calculate how many numbers in the list are smaller than it. Write a function that does the calculation and returns the result (as a list). For example, if you are given [6,5,4,8], your function should return [2, 1, 0, 3] because there are two numbers less than 6, one number less than 5, zero numbers less than 4, and three numbers less than 8. Sample Input smaller_than_current([6,5,4,8]) Sample Output [2, 1, 0, 3]arrow_forwardJS Write a function named list_concat that has a single parameter. This parameter will be a list/array. The parameter's entries will be strings. Your function needs to return a string. The returned string's value should be the concatention of all of the entries in the parameter with a space after each entry. Sample test cases: list_concat(["single"]) evaluates to "single list_concat(["limit", "break", "ready"]) evaluates to "limit break readyarrow_forward
- Need some help on this Python Quesionarrow_forwardin python Integer num_samples is read from input, representing the number of data samples to be read from input. List data_list contains the data samples read from the remaining input. For each element in data_list: If the element is greater than 25, output the element followed by ' at index ', the element's index in the list, and ' is flagged'. Otherwise, output the element followed by ' at index ', the element's index in the list, and ' is normal'.arrow_forwardWrite a function called find_duplicates which accepts one list as a parameter. This function needs to sort through the list passed to it and find values that are duplicated in the list. The duplicated values should be compiled into another list which the function will return. No matter how many times a word is duplicated, it should only be added once to the duplicates list. NB: Only write the function. Do not call it. For example: Test Result random_words = ("remember","snakes","nappy","rough","dusty","judicious","brainy","shop","light","straw","quickest", "adventurous","yielding","grandiose","replace","fat","wipe","happy","brainy","shop","light","straw", "quickest","adventurous","yielding","grandiose","motion","gaudy","precede","medical","park","flowers", "noiseless","blade","hanging","whistle","event","slip") print(find_duplicates(sorted(random_words))) ['adventurous', 'brainy', 'grandiose', 'light', 'quickest', 'shop', 'straw', 'yielding']…arrow_forward
