And to find …With the more general concept of shape, numpy developers choose to implement __len__ as the first dimension. Python maps len (obj) onto obj.__len__. X.shape returns a tuple, which does have a len - which is the number of dimensions, X.ndim. X.shape [i] selects the ith dimension (a straight forward application of tuple indexing). Share.

And also a range: new_range = (0, 1) max_range = max (new_range) min_range = min (new_range) The first thing I do here is to see what is the current range of numbers between the minimum and the maximum. Since we want the minimum to be 0.0 and the maximum 1.0, we must divide the range (1.0 - 0.0, maximum minus the minimum), that is 1.0, between ...

Rotating a vector around the origin (a point) in 2D simply means rotating it around the Z-axis (a line) in 3D; since we're rotating around Z-axis, its coordinate should be kept constant i.e. 0° (rotation happens on the XY plane in 3D). In 3D rotating around the Z-axis would be. A short informal answer: The distance vector ΔS Δ S between two close (differential) points is. ΔS = (Δx, Δy, Δz). Δ S = ( Δ x, Δ y, Δ z).
