Hello there: I must follow the below instructions very carefully to complete the code. My code is not working. Can you help me to fix it? In the def reverse function, I'm stuck there with the instructions.

Thanks in advanced!

The instructions are in the code comments. Also, you can see some output examples.

import numpy as np

# SIZE is a global constant, use this throughout your program.

# you should be able to change this to any int and your

# whole program will still work correctly. TEST THIS!

SIZE = 10

STATS_SIZE = 4

MULTIPLIER = 10

# initialize the array with 10, 20, 30, etc.

def make_array():

  # creates a numpy array of size SIZE filled with 0s.

  nums = np.array([0] * SIZE, dtype=int)

  # now fill it with 10,20,30, etc ***using a loop*** and return it

def calc_stats(nums):

  stats = np.array([0] * STATS_SIZE, dtype = int)

  stats[0] = np.min(nums)

  stats[1] = np.max(nums)

  stats[2] = np.sum(nums)

  stats[3] = int(np.mean(nums))

  # make an integer array of size 4 to hold stats

  # calculate four basic stats and put them in the size 4 array in this order:

  # min, max, total, average

  # min and max will just be the first and last numbers from the nums array

  # average may calculate as a float, make it an int to store it in the stats array

  # return the stats array with all the correct stats in order

def display_stats(stats):

  print("Min: ", stats[0])

  print("Max; ", stats[1])

  print("Total: ", stats[2])

  print("Average: ", stats[3])

  print()

  # make this display everything as shown in the examples

  # you can hard code the indexes, you don't need a loop

def reverse_array(arr):

  for i in range(SIZE):

    nums[i] = (i + 1) * MULTIPLIER

  # this will accept an integer array

  # do NOT alter the array passed in. use it as-is

  # put the numbers from arr in another array in reverse order

  # you MUST use a loop

  # and return the reversed array

def main():

  # this function is complete, DO NOT MODIFY IT

  # you may modify it while you program, but when you turn in for grading

  # it must be returned to EXACTLY this state

  # this will initialize the array with 10,20,30... etc

  numbers = make_array()

  # show the array

  print("All the numbers...")

  print(numbers)

  print()

  # this will calculate 4 stats, min, max, total, average

  statistics = calc_stats(numbers)

  # this will initialize the array with 10,20,30... etc

  display_stats(statistics)

  # this will reverse the array

  numbers = reverse_array(numbers)

  # show the array again

  print("All the numbers in revered order...")

  print(numbers)

  print()

# this starts the program

# do not change this line

main()

Hints

● You can put the line pass in your empty functions as a temporary placeholder to make Python ignore the fact there is no code inside the function. This is so your program won't crash while you work on it. It can be like this: def some_function(): pass

● To start, put pass in your empty functions and comment out all the code in main() except for this part: Then work on just the make_array() function. Get that to work by itself first.

● Similarly, then uncomment the line statistics= calc_stats(numbers) and work on just that function. You can add a debug line below it like this: print(statistics) so you can see what calc_stats() is doing.

● Continue in that way. Uncomment just the next part you want to work on, and add debug statements as needed. Make sure you remove all debug statements before you submit.

● Make sure you return main() back to its original state
