In Python, functions are first-class objects. A first-class object is an object that can be assigned to a variable, passed as an argument to a function, or used as a return value in a function. So, you can use a function object as a return value in any return statement. A function...
PyObject* tanh_impl(PyObject* /* unused module reference */, PyObject* o) { double x = PyFloat_AsDouble(o); double tanh_x = sinh_impl(x) / cosh_impl(x); return PyFloat_FromDouble(tanh_x); } At the end of the file, add a structure to define how to present the C++ tanh_...

在Python 中,我们使用 return Tuple 的方式,从函数中返回多个参数,并直接赋值给变量。 # A Python program to return multiple # values from a method using tuple # This function returns a tuple def fun(): str = "geeksforgeeks" x = 20

def __unicode__(self): return self.name 1. 2. 对__unicode__()的唯一要求就是它要返回一个unicode对象 如果`` __unicode__()`` 方法未返回一个Unicode对象,而返回比如说一个整型数字,那么Python将抛出一个`` TypeError`` 错误,并提示:”coercing to Unicode: need string or buffer, int found” ...
One especially important use case is when you want to return more than one object from your Python function. 在这种情况下,您通常会将所有这些对象包装在一个元组对象中,然后返回该元组。 In that case, you would typically wrap all of those objects within a single tuple object, and then return th...
