Looks like a trick question.
There is no Array in Python but an object List exists which can be used to the same end.
lst=["a", "b", "c", "e"]
There is no Array in Python but an object List exists which can be used to the same end.
- The List may contain different list items or same kind of list items.
- The List is indexed and zero based. The first list item has an index 0.
- You can retrieve list items using their index. Even negative index is OK.
lst=["a", "b", "c", "e"]
The list can have strings like this as well:
lst2=['a', 'b', 'c', 'e']
They both evaluate to the same: ['a', 'b', 'c', 'e']
List may contain different types of List Items as in this definition.
lst2=["ab", 8, True, 5.8]
Retrieving list items using index
>>> lst[0]
'a'
>>> lst[-1]
'e'
>>> lst2[-2]
True
>>> lst[5]
Traceback (most recent call last):
File "", line 1, in
IndexError: list index out of range
>>> lst[-1]
'e'
>>> lst2[-2]
True
>>> lst[5]
Traceback (most recent call last):
File "
IndexError: list index out of range
Negative Index
>>> lst[-1]
'e'
>>> lst2[-2]
True
'e'
>>> lst2[-2]
True
These evaluations were carried out using Python 3.6.2
