How do we return a sparse matrix and an array data from a function. My sparse matrix is
我们如何从函数返回稀疏矩阵和数组数据。我的稀疏矩阵是
sparse_mat
sparse_mat
<540x5550 sparse matrix of type '' with 9068 stored elements in COOrdinate format>
<540x5550类型为''的稀疏矩阵，其中包含9068个以COOrdinate格式存储的元素>
and the other data is session_id:
其他数据是session_id：
array([['192.168.113.111_timesofindia.indiatimes.com_1', 'User'],
['192.168.113.111_timesofindia.indiatimes.com_2', 'User'],
dtype='|S46')
I want to return both these data from a function.Thanks
我想从函数中返回这两个数据。谢谢

You can return more than one value from a Python function by returning a tuple:
您可以通过返回元组从Python函数返回多个值：
return sparse_mat, session_id
The caller can get the returned value by something like:
调用者可以通过以下方式获取返回值：
m, id = your_function()
Oh, and it doesn't make any difference if there are two different data types. You can return two values of the same type too of course.
哦，如果有两种不同的数据类型，它没有任何区别。当然，您也可以返回两个相同类型的值。

Use a tuple:
使用元组：
def foo(x, y):
sum = x + y
return (x, y, sum)
See? I returned 3 items. And what is more, if I know the airity of the tuple, then I can use an extractor to capture them:
看到？我退回了3件物品。更重要的是，如果我知道元组的空气，那么我可以使用一个提取器来捕获它们：
(m, n, total) = foo(4, 5)
wherein m is assigned 4, n is assigned 5 and total is assigned 9.
其中m被指定为4，n被指定为5，总数被指定为9。

例子
def return2():
a = {1:1}
b = 'b'
return a,b
def anotherReturn2():
a = {1:1}
b = 'b'
return {'a' : a, 'b' : b}
a_1, b_1 = return2()
a_2 = return2()[0]
b_2 = return2()[1]
print a_1, b_1, a_2, b_2
a_1, b_1 = anotherReturn2()
a_2 = anotherReturn2()['a']
b_2 = anotherReturn2()['b']
print a_1, b_1, a_2, b_2
>>>
{1: 1} b {1: 1} b
a b {1: 1} b
>>>
