Python code to demonstrate why the output of numpy.where(condition) is not an array, but a tuple of arrays # Import numpyimportnumpyasnp# Creating a numpy arrayarr=np.array([ [1,2,3,4,5,6], [-2,1,2,3,4,5]])# Display original arrayprint("Original array:\n",...
Python Collections (Arrays) There are four collection data types in the Python programming language: Listis a collection which is ordered and changeable. Allows duplicate members. Tupleis a collection which is ordered and unchangeable. Allows duplicate members. ...

Matrices are generally represented as 2-D arrays of shape (M,N). python # Import numpy import numpy as np # Create numpy arrays from lists x = np.array([1, 2, 3]) y = np.array([[3, 4, 5]]) z = np.array([[6, 7], [8, 9]]) # Get shapes print(y.shape) # (1, ...
I noticed some strange behaviour when saving tuples of ndarrays. When one of them is clearly a different shape it works correct. But if the arrays seem similar (ie. their first dimension is the same), but they are not 'broadcastable' an ...
Just like in other Python container objects, the contents of an array can be accessed and modified by indexing or slicing the array. Unlike the typical container objects, different arrays can share the same data, so changes made on one array might be visible in another. ...

Replacement to #3296. As discussed there, we believe it's safe to use PyTuple_New when there is confidence of no Python code running while filling the uninitialized tuple. Therefore in this PR I ad...
