Set Operations

• NumPy provides functions for set-like operations on arrays.

• union1d()
• intersect1d()
• setxor1d()
• setdiff1d()

What is Union?

• Union returns the unique values present in either array.

Step 1:

Output:

What is Intersection?

• Intersection returns the values common to both arrays.

Step 1:

Output:

What is Set Difference?

• setdiff1d() returns values that exist in the first array but not in the second.

Step 1:

Output:

What is Set XOR?

• setxor1d() returns values that are in either array but not in both.

Step 1:

Output:
