The Python language provides a protocol for accessing memory buffers like the data stored in a MATLAB array. MATLAB implements this Python buffer protocol for MATLAB arrays so that you can read MATLAB arrays directly from Python code, running in the same process as MATLAB, without copying data. ...
NumPy, short for Numerical Python, is one of the most important foundational packages for numerical computing in Python. Most computational packages providing scientific functionality use NumPy’s array objects as the lingua franca for data exchange. ...
So, the object's id is unique only for the lifetime of the object. After the object is destroyed, or before it is created, something else can have the same id. But why did the is operator evaluate to False? Let's see with this snippet. class WTF(object): def __init__(self): ...
