Please someboby help me


#1

Write a function called manipulate_data which will act as follows:

When given a list of integers, return a list, where the first element is the count of positives numbers and the second element is the sum of negative numbers.

NB: Treat 0 as positive.

This is my code so far

def manipulate_data(data):
    return [len([n for n in data if isinstance(n, int) and n >= 0]), sum(n for n in data if isinstance(n, int) and n < 0)]

it should satisfy the following test

import unittest

class ManipulateDataTestCases(unittest.TestCase):
  def test_only_lists_allowed(self):
    result = manipulate_data({})
    self.assertEqual(result, 'Only lists allowed', msg='Invalid argument')

  def test_it_returns_correct_output_with_positives(self):
    result = manipulate_data([1, 2, 3, 4])
    self.assertEqual(result, [4, 0], msg='Invalid output')
    
  def test_returns_correct_ouptut_with_negatives(self):
    result = manipulate_data([1, -9, 2, 3, 4, -5]);
    self.assertEqual(result, [4, -14], msg='Invalid output')

First of all, please put your code in backticks, so it looks clearer here (a guide to formatting your post can be found here: https://discuss.codecademy.com/t/how-do-i-format-code-in-my-posts/51139/2).

Second thing — what problem exactly do you have with this code?


#3

I keep getting this error:
Failure in line 11, in test_only_lists_allowed self.assertEqual(result, 'Only lists allowed', msg='Invalid argument') AssertionError: Invalid argument


#4

Is this even codecademy related?

why not list comprehension for the sum as well and cast it to a list()? You might need to use an additional set of brackets, so both list comprehensions execute first


#5

Please hav you find a solution to the error? Please help me with the correct answer


#6

Asking for answers is not according to the guildines, is this even codecademy related?
