Question

In Python, colours can be represented in a number of ways: as the colour name (a string), as a hexadecimal number (stri preceded with # ) and as RGB values (a sequence of 3 integers in the range 0 to 255 inclusive, each representing one of (R)ed, (G)reen and (B)lue). Consider the following Python data structure, which contains data representing the name, hexadecimal value and RGB values of some colours: colours- [['black', '#000000', [0,0,0]], ('white','#FFFFFF. [255, 255,25511 ['red', '#FF0000', (255,0,0)), ['green ' , '#00FF00', [0,255,011, ['blue', '#0000FF', [0,0, 25511] Which of the descriptions below best describes the purpose of the following print statement? print (colours (11 t2) 1211 Prints the green RGB element of the colour black Prints the red RGB element of the colour 'white Prints the blue RGB element of the colour blue Prints the green RGB element of the colour red Prints the blue RGB clement of the colour white Prints the green RGB element of the colour white Prints the green RGB element of the colour green Prints the red RGB element of the colour 'red

Explanation / Answer

The correct option is => Prints the blue RGB element of the colour 'white'

Explanation:
Given, colours[1][2][2]
-> colours[1] - the pointer will first move to the row with the index count 1, i.e to the 2nd row.
-> colours[1][2] - Next, at the 2nd row the pointer will read the column with the index number 2 i.e., the third column.
-> It means now the pointer is in the white row and RGB values' column.
-> colours[1][2][2] - Now at the RGB values column the pointer will read the value with index 2 i.e. the 3rd element.

==> ['white', '#FFFFFF', [255, 255, 255]

Since the third element is the blue RGB element, hence so the answer.
