M3 R5: Programming and Problem Solving through Python

Set

See Explanation !

1 Suppose d = {“john”:40, “peter”:45}, what happens when we try to retrieve a value using the expression d[“susan”]?

मान लीजिए d = {“john”:40, “peter”:45}, तब क्या होता है जब हम d[“susan”] अभिव्यक्ति का उपयोग करके मान प्राप्त करने का प्रयास करते हैं?

Since “susan” is not a value in the set, Python raises a KeyError exception

It is executed fine and no exception is raised, and it returns None

Since “susan” is not a key in the set, Python raises a KeyError exception

Since “susan” is not a key in the set, Python raises a syntax error
