assert_array_equal checks for exact equality. That’s fine for integer and boolean values, but often fails with floating point values because of very slight differences in the results of values calculated different ways or on different computers. For comparing floating point values I use assert_al...

Write a NumPy program to test element-wise for complex numbers, real numbers in a given array. Also test if a given number is of a scalar type or not. Click me to see the sample solution 9. Test Element-Wise Tolerance Equality

Finally, you need to test that the length of each dimension is either (drawn from) a common length, or 1. A trick for doing this is to first mask the array of NumPy “shape-tuples” in places where it equals one. Then, you can check if the peak-to-peak (np.ptp()) column-...
