In python I need to know how to :

Add Median Score Function

>>> Add a function get_median_score() to calculate the median (Links to an external site.) score (see link for calculation), where:

• Single list parameter
• Guardian code
  • Use isinstance() to validate parameter is a list, print 'List argument expected' if parameter not a list, and return -1
  • If list is empty return 0
• If list only contains a single element, return that value as the median
• If the list contains even number of elements, average the two middle values as the median
  • Remember to account for the fact that 0 elements might indicate the number of elements is even if you use the modulus operator, so make sure you have elements in the list as well
• If the list contains an odd number of elements, the middle element is the median score
• Return the median score

>>> Save and run the program, and test the median score function.

Print Grade Range Counts

Typical grading is as follows:

• A: 90+
• B: 80 - 89
• C: 70 - 79
• D: 60 - 69
• F:

Add two functions that will enable you to output the number of A's, B's, C's, D's and F's based on the scores.

>>> Add function count_range() to count the number of scores within a low and high range, where:

• List parameter, low score, high score
• Guardian code
  • Use isinstance() to validate parameter is a list, print 'List argument expected' if parameter not a list, and return -1
  • If start or end are not integers, print 'start and end must be integers' and return -1
  • If start > end or start == end, print 'start must be and return -1
  • If list is empty return 0
• Count the number of integers within the start and end range (use >= and
• Return the number of integers within the start and end range

>>> Save and run the program, and test the range count function.

>>> Add function list_range() to call count_range() with ranges appropriate to produce a list of the A, B, C, D and F grades and print out results similar to the image below.

Here is what I got so far:

# import random numbers

import random

def gen_random_integer_list(num, start_range = 1, end_range = 100, sort_list = 'N'): # get random integer list # num = number of integers in list # start_range & end_range = range of integers allowed # sort_list: if Y sort list, if N do not sort #return variable t = [] # test if parameters are valid if num 0') # make sure number is integer elif not isinstance(num, int): print('num must be an integer') # make sure range uses integers elif not isinstance(start_range, int) or not isinstance(end_range, int): print('start_range and end_range must be integers')

else: for i in range(num): r = random.randint(start_range, end_range) t.append(r)

if sort_list.upper() == 'Y': t.sort() # return the list return t

def get_high_score(t): if not isinstance(t, list): print ('List argument expected') elif len (t) > 0: new_t = t[:] new_t.sort() high_score = new_t[-1]

return high_score

def get_low_score(t): if not isinstance(t, list): print ('List argument expected') elif len (t) > 0: new_t = t[:] new_t.sort() low_score = new_t[0]

return low_score

def average_score(t): if not isinstance(t, list): print ('List argument expected') elif len (t) > 0: new_t = t[:] average_score = sum(t)/len(t)

return average_score
