Решение с колекция:

n = float(input())

output = {n == 0: 'zero',
          0 < n < 1: 'small positive',
          1 <= n <= 1000000: 'positive',
          n > 1000000: 'large positive',
          0 > n > -1: 'small negative',
          -1 >= n >= -1000000: 'negative',
          n < -1000000: 'large negative'}

print(output[True])
