For returning multiple values from a function, we can return tuple, list or dictionary object as per our requirement. Method 1: Using tuple def func(x): y0 = x+ 1 y1 = x * 3 y2 = y0 ** 3 return (y0, y1, y2) However, above program get problematic as the number of values r...
pass ... >>> function(0, a=0) Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: function() got multiple values for keyword argument 'a' 当**name存在表单的最终形式参数时,它接收包含除了与形式参数相对应的所有关键字参数的字典(参见映射类型 - 字典)。

Effective Python 笔记 (Chapter 3 Functions) Item 19: Never Unpack More Than Three Variables When Functions Return Multiple Values Unpacking into four or more variables is error prone and should be avoided; instead, return a small class or namedtuple instance. ...
return result ... >>> f100 = fib2(100) # call it >>> f100 # write the result [0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89] 此示例中,像往常一样,演示了一些新的 Python 功能: return 语句会从函数内部返回一个值。 不带表达式参数的 return 会返回 None。 函数执行完毕退出也会返...
When you’re writing a function that returns multiple values in a single return statement, you can consider using a collections.namedtuple object to make your functions more readable. namedtuple is a collection class that returns a subclass of tuple that has fields or attributes. You can access ...
Returning Multiple Values in Python - GeeksforGeeks 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 ...
