For example: I'm writing simple class:
class Numbers:
def __init__(self, numbers):
self._numbers = numbers
def get_all(self):
for number in self._numbers:
yield number
If I want to add another method for yielding even numbers only, I may
use:
def get_even(self):
for numbers in self._numbers:
if numbers % 2 == 0:
yield number
or, I can use public method 'get_all' instead of using private
attribute '_numbers', like:
def get_even(self):
for numbers in self.get_all():
if numbers % 2 == 0:
yield number
Which coding style do you prefer? I'm more toward public API way,
since it requires less code change if I refactor private data
structure later.
Plz give pros and cons of these.
