pls use Python do this

Problem Multi-level encryption and decryption

Clearly the basic Caesar cipher is not terribly secure. To make things a little harder to crack, you will now implement a multi-level Caesar cipher. Instead of shifting the entire string by a single value, you will perform additional shifts at specified locations throughout the string. This function takes a string text and a list of tuples shifts. The tuples in shifts represent the location of the shift, and the shift itself. For example a tuple of (0,2) means that the shift starts are position 0 in the string and is a Caesar shift of 2. Additionally, the shifts are layered. This means that a set of shifts [(0,2), (5, 3)] will first apply a Caesar shift of 2 to the entire string, and then apply a Caesar shift of 3 starting at the 6th letter in the string.

To do this, implement the following function according to the specification.

def apply_shifts(text, shifts):

"""

Applies a sequence of shifts to an input text.

text: A string to apply the Ceasar shifts to

shifts: A list of tuples containing the location each shift should

begin and the shift offset. Each tuple is of the form (location,

shift) The shifts are layered: each one is applied from its

starting position all the way through the end of the string.

returns: text after applying the shifts to the appropriate

positions

Example:

>>> apply_shifts("Do Androids Dream of Electric Sheep?", [(0,6), (3, 18), (12, 16)])

'JufYkaolfapxQdrnzmasmRyrpfdvpmEurrb?'
