Answer:
1)
The given tuple is as follows:
|
Index |
0 |
1 |
2 |
3 |
4 |
|
Index (reference to the last element’s position) |
-5 |
-4 |
-3 |
-2 |
-1 |
|
Value |
'abcd' |
786 |
2.23 |
'john' |
70.2 |
The index referencing 2: means 2nd element to last element.
Therefore “print(print(tuple[2:]))” prints (2.23, 'john', 70.2)
2)
The index referencing -3: means , -3 element to last element.
Therefore “print(print(tuple[2:]))” prints “ (2.23, 'john', 70.2)”
3)
When referencing the elements with respect to the last element’s position, we start with the index of the last element, that is -1.
There for the index of the beginning element is “ -1”.
4)
Unlike lists, dictionaries are unordered sets of elements. Each element in the dictionary is associated with a key(name).Since dictionary does not support indexing, keys(names),are used to uniquely identify the elements.
Therefore the correct option is “name”.
