How long can you stand it, 5% of useful information is lost in the rubbish of imbeciles who can not even program, but prove something, criticize ... While mom cooks cabbage soup in the kitchen ...

They say they don't know how to program, but they prove their point by criticizing while their mother makes cabbage soup in the kitchen.)

Evgeny Dyuka:
There are several people here who are frightened by the thought "what if they succeed".
Peter, accept the fact that sooner or later they will. And (oh my God!) they'll make money on it.

Didn't notice the post.

Yes, apparently very scared)). It smells bad.)))

I'm probably wrong, trying to tell someone something. There are two sides to the market and the first always gives money to the second. I guess I was on the wrong side. I'll be gone forever...))))))

It's already too much. I've had enough fun, I've got the likes, that's enough for today.

It is better to make such generalizations about polymorphism in your own thread about AI. It's more appropriate there.

Yes, the topic there stimulates synapse connections responsible for higher forms of thinking, communication , andassociation. It is more appropriate there.

Representation or surface copy

Different array objects can use the same data. The view() method creates a new array object that is a representation of the same data.

>>> c = a.view()
>>> c is a
False
>>> c.base is a  # c это представление данных, принадлежащих a
True
>>> c.flags.owndata
False
>>>
>>> c.shape = (2,6)  # форма а не поменяется
>>> a.shape
(3, 4)
>>> c[0,4] = 1234  # данные а изменятся
>>> a
array([[  0, 1, 2, 3],
       [1234, 5, 6, 7],
       [ 8, 9, 10, 11]])

An array slice is a view:

>>> s = a[:,1:3]
>>> s[:] = 10
>>> a
array([[  0, 10, 10, 3],
       [1234, 10, 10, 7],
       [ 8, 10, 10, 11]])
