Test: Tuples, Dictionary and Sets - 1 - EmSAT Achieve MCQ

Tuples maintain the order of elements, unlike sets or dictionaries.

Lists are ordered collections, whereas dictionaries are unordered and use key-value pairs.

The add() method is used to add an element to a set in Python.

Tuple indexing starts from 0, so my_tuple[2] will access the third element (index 2) of the tuple.

Sets do not allow duplicate elements. Each element in a set is unique.

The get() method returns the value associated with the specified key. If the key is not found, it returns None.

The add() method adds an element to the set. In this case, 6 is added to the set, resulting in a total of 6 elements.

Tuples are immutable, which means you cannot change individual elements once a tuple is created.

The del keyword is used to remove an item from a dictionary based on its key.

The remove() method removes an element from a set. If the element is not found, it raises a KeyError.

The intersection() method returns a new set containing the elements common to both set1 and set2.

The pop() method removes the item with the specified key from the dictionary and returns its value.

The + operator can be used to concatenate tuples. The comma at the end ensures that the second tuple is recognized as a tuple.

The given code uses a set comprehension to create a new set where each element is the square of the corresponding element in the original set.

The clear() method removes all items from the dictionary, resulting in an empty dictionary.
