Python Set difference_update() Method Example

Python Set difference_update() is an inbuilt method that finds the difference of two sets and returns the difference as a new set.

Python Set difference_update() is an inbuilt method that finds the difference of two sets; also it modifies the caller set with the result set. In the set difference method, we find the difference between the two sets and returns the difference as a new set.

For example,

if  A = {a,b,c,d,e,f} and B={a,e,f,g} are two sets and if we want to find A-B then the result will be {b,c,d}, also this method will modify the set A with values {b,c,d}.

Similarly, if we want to find B-A, then the result will be {f,g}, and this method will modify the set B with this value, but set A will remain unchanged.
