Question
What will be the output of the following Python code?>>> a={1,2,3}>>> b=a>>> b.remove(3)>>> a{1,2,3}Error, copying of sets isn’t allowed{1,2}Error, invalid syntax for remove
Solution
The output of the Python code will be {1,2}.
Here's the step by step explanation:
- A set 'a' is created with elements 1, 2, and 3.
- 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.
- 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.
- When you print 'a', it shows the set after the removal operation, which is {1,2}.
