NumPy’s main object is the homogeneous multidimensional array. It is a table of elements (usually numbers), all of the same type, indexed by a tuple of non-negative integers. In NumPydimensionsare calledaxes. For example, the array for the coordinates of a point in 3D space,[1, 2, 1...
Index-based selection is great, but what if you want to filter your data based on more complicated nonuniform or nonsequential criteria? This is where the concept of a mask comes into play. A mask is an array that has the exact same shape as your data, but instead of your values, ...
