# Bài 4.5

# -------

# Given an integer list from -10 to 10 except 0, write a function:

# - calculate its sum without using function ``sum``.

# - calculate its product

# Return a tuple (sum, product).

# Input::

# li = range(-10, 11)

# li = list(li)

# li.remove(0)

# Compare output with this::

# from functools import reduce

# assert sum_and_product(li) == (sum(li), reduce(lambda x,y: x*y, li))

lst = list(range(-10, 11))

lst.remove(0)

sum_lst = 0

for num in lst:

sum_lst = sum_lst + int(num)

assert sum(lst) == sum_lst, 'You sum this list incorrect'

print(sum_lst)
