Making proper sets
unique(ar[, return_index, return_inverse, …]) |
Find the unique elements of an array. |
Boolean operations
in1d(ar1, ar2[, assume_unique, invert]) |
Test whether each element of a 1-D array is also present in a second array. |
intersect1d(ar1, ar2[, assume_unique]) |
Find the intersection of two arrays. |
isin(element, test_elements[, …]) |
Calculates element in test_elements, broadcasting over element only. |
