код:

   if i != 0:

       n.append(i)

mine = 0

maxe = 0

pos = 0

for i in n:

   pos += 1

   if i < 0:

       x1 += i

   if i % 5 == 0 and i < 20:

       x2 += 1

   if pos % 2 == 0:

       x3 *= i

   if pos == 1:

       mine = i

   elif pos == 20:

       maxe = i

   if i % 3 == 0 and i > 0:

       x5.append(str(i))

x4 = mine + maxe

print('  '.join(x5))
