Consider the following code:
result = {'A rabbit', 'The Scourge of Caerbannog', 'The most cruel and bad tempered rodent'}
result.remove('The most cruel and bad tempered rodent')
result.remove('The Scourge of Caerbannog')
result.add(42)
What value is stored in result?

Question

BlackTom AI · Accepted Answer

The given code creates a set containing three distinct strings: 'A rabbit', 'The Scourge of Caerbannog', and 'The most cruel and bad tempered rodent'.
Next, it removes two elements by value: first 'The most cruel and bad tempered rodent' is removed, leaving {'A rabbit', 'The Scourge of Caerbannog'}; then 'The Scourge of Caerbannog' is removed, leaving {'A rabbit'}.
Finally, result.add(42) inserts the integer 42 into the set, so the set becomes {'A rabbit', 42}.
In Python, when a set is printed, the order of elements is not guaranteed, so the representation commonly appears as {42, 'A rabbit'} or {'A rabbit', 42}. The two elements are exactly the string 'A rabbit' and the integer 42, in an unordered collection.
Therefore, the value stored in result is a set containing 42 and 'A rabbit'. The provided options show {42, 'A rabbit'} (duplicated), which matches the expected contents, differing only in element order.

Consider the following code: result = {'A rabbit', 'The Scourge of Caerbannog', 'The most cruel and bad tempered rodent'} result.remove('The most cruel and bad tempered rodent') result.remove('The Scourge of Caerbannog') result.add(42) What value is stored in result? 单项选择题
