I wrote the below code

    new_methods = _create_methods(arith_method, comp_method, bool_method, use_numexpr, default_axis=None, special=True, have_divmod=have_divmod)
    def _wrap_inplace_method(method):
        '\n                                return    an    inplace    wrapper    for    this    method\n                                '
        def f(self, other):
            result = method(self, other)
            self._update_inplace(result.reindex_like(self, copy=False)._data, verify_is_copy=False)
            return self
        return f
    new_methods.update(dict(__iadd__=_wrap_inplace_method(new_methods['__add__']), __isub__=_wrap_inplace_method(new_methods['__sub__']), __imul__=_wrap_inplace_method(new_methods['__mul__']), __itruediv__=_wrap_inplace_method(new_methods['__truediv__']), __ipow__=_wrap_inplace_method(new_methods['__pow__'])))
    if (not compat.PY3):
        new_methods['__idiv__'] = new_methods['__div__']
    add_methods(cls, new_methods=new_methods, force=force, select=select, exclude=exclude)

What's a good function header?

Here's a good function header?
