Question

Can you write the function in python?

def remove_outliers(data, num_outliers):
# When analyzing data collected as a part of a science experiment it
# may be desriable to remove the most extreme values before performing
# other calculations. Complete this function which takes a list of
# values and an non-negative integer, num_outliers, as its parameters.
# The function should create a new copy of the list with the num_outliers
# largest elements and the num_outliers smallest elements removed.
# Then it should return teh new copy of the list as the function's only
# result. The order of the elements in the returned list does not have to
# match the order of the lemetns in the original list.
# input1: data (list)
# input2: num_outliers (int)

# output: list

It has to pass this test.

import random
random.seed(1234)
data = [random.randint(50, 150) for ele in range(100)]
data[45] = 1
data[46] = 2
data[90] = 250
data[34] = 300

result = [50, 50, 51, 52, 52, 52, 53, 53, 54,
55, 55, 55, 55, 56, 58, 58, 59, 59, 59, 60, 61, 61,

135, 136, 138, 140, 141, 148, 148, 149, 149, 150]

assert remove_outliers(data, 2) == result

Answer 1

def remove_outliers(data, num_outliers):
copy = data[:]
copy=sorted(copy)
copy=copy[num_outliers:len(data)-num_outliers]
return copy
