So you know how some people say that "Good code documents itself"?
Is this what they meant?
def self_documenting_sum(a, b): with open(__file__, 'r') as source: data = source.read().split('\n') with open(__file__, 'w') as source: if not data.startswith(' "'): documentation = ' """Sums up two integers"""' new_source = data[:] new_source.insert(1, documentation) source.write('\n'.join(new_source)) else: source.write('\n'.join(data)) return a + b print(self_documenting_sum(2,5))
(It's a Python script that adds docstring to its only function on the first run.)
edit: I expanded on the idea a bit in hamatti/self-documenting-code
