1)

import random

number_list = []

for n in range(10):

   number_list.append(random.randint(-10, 10))

print(number_list)

number_list = [number * -1 for number in number_list]

print(number_list)

2)

import random

number_list = []

for n in range(10):

   number_list.append(random.randint(-10, 10))

amount = 0

for number in number_list:

   amount += number

print(amount)

3)

import random

number_list = []

for i in range(10):

   number_list.append(random.randint(-10, 10))

number_list = [number ** 2 for number in number_list]

amount = 0

for n in number_list:

   amount += n

print(amount)

4)

import random

number_list = []

for n in range(10):

   number_list.append(random.randint(-10, 10))

negative_numbers = []

positive_numbers = []

for number in number_list:

   if number < 0:

       negative_numbers.append(number)

   elif number > 0:

       positive_numbers.append(number)

amount_positive = 0

amount_negative = 0

for n in negative_numbers:

   amount_negative += n

print('сумма отрицательных чисел: ' + str(amount_negative))

for p in positive_numbers:

   amount_positive += p

print('сумма положительных: ' + str(amount_positive))
