Ruby - 相当于Python __str __()方法？

在Ruby中,是否有相当于__str__()您可以在Python类上定义的方法？

你可以使用to_s.

FWIW,检查可能更喜欢__repr__()比__str__()

repr(个体经营)

Called by the repr() built-in function and by string conversions (reverse quotes) to compute the ``official'' string representation of an object. If at all possible, this should look like a valid Python expression that could be used to recreate an object with the same value (given an appropriate environment). If this is not possible, a string of the form "<...some useful description...>" should be returned. The return value must be a string object. If a class defines __repr__() but not __str__(), then __repr__() is also used when an ``informal'' string representation of instances of that class is required.
