Solution

The output of the Python code will be {1,2}.

Here's the step by step explanation:

  1. A set 'a' is created with elements 1, 2, and 3.
  2. The set 'a' is assigned to 'b'. In Python, this doesn't create a new copy of the set. Instead, 'b' is just another name pointing to the same set that 'a' points to.
  3. The remove() function is called on 'b' to remove the element 3. Since 'b' and 'a' are pointing to the same set, this operation affects 'a' as well.
  4. When you print 'a', it shows the set after the removal operation, which is {1,2}.
