Part 3 - Coding Exercise: Decoding a Message from a Text FileIn this exercise, you will develop a function named . This function should read an encoded message from a .txt file and return its decoded version as a string.decode(message_file)Note that you can write your code using any language and IDE you want (Python is preferred if possible, but not mandatory).Your function must be able to process an input file with the following format:3 love6 computers2 dogs4 cats1 I5 youIn this file, each line contains a number followed by a word. The task is to decode a hidden message based on the arrangement of these numbers into a "pyramid" structure. The numbers are placed into the pyramid in ascending order, with each line of the pyramid having one more number than the line above it. The smallest number is 1, and the numbers increase consecutively, like so: 1 2 34 5 6The key to decoding the message is to use the words corresponding to the numbers at the end of each pyramid line (in this example, 1, 3, and 6). You should ignore all the other words. So for the example input file above, the message words are:1: I3: love6: computersand your function should return the string "I love computers".Please submit the complete code for the decode function:

def decode(message_file):
    # Open the file
    with open(message_file, 'r') as file:
        lines = file.readlines()

    # Create a dictionary to store the number-word pairs
    message_dict = {}
    for line in lines:
        number, word = line.split()
        message_dict[int(number)] = word

    # Calculate the pyramid ends
    pyramid_ends = []
    i = 1
    while i <= len(message_dict):
        pyramid_ends.append(i)
        i += len(pyramid_ends) + 1

    # Decode the message
    message = ' '.join([message_dict[i] for i in pyramid_ends])

    return message
