20 / 35Tuples and SetsMediumPython Basics

What will be the output when Ravi executes this code that modifies a set by removing elements?

my_set = {10, 20, 30, 40, 50}
my_set.discard(30)
my_set.remove(40)
print(my_set)

  1. `{10, 20, 50}`

  2. `{10, 20, 30, 40, 50}`

  3. `{30, 40}`

  4. `{10, 20}`

Show answer & explanation

Correct answer

`{10, 20, 50}`

Explanation

Both `.discard()` and `.remove()` remove elements from a set. The difference is that `.discard()` doesn't raise an error if the element doesn't exist, while `.remove()` does. Here, both 30 and 40 are removed, leaving `{10, 20, 50}`.
