Create a basic Python program to classify a list of positive and negative integer numbers.
List of numbers: [2, 4, -3, 6, -7, 0]
positive_numbers = []
negative_numbers = []

for num in numbers:
 if num > 0:
  positive_numbers.append(num)
 else:
  negative_numbers.append(num)

print('Positive numbers:', positive_numbers)
print('Negative numbers:', negative_numbers)
