Part $3-$ Coding Exercise: Decoding a Message from a Text File

In 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

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:

number is $1,$ and the numbers increase consecutively, like so:

$1$

$23$

$456$

$1$: $I$

$3$: love

$6$: computers

and your function should return the string "I love computers".

Please submit the complete code for the decode function

$1$

Explain how your code works in two or more complete sentences.

So for the example we shared above, you'd paste 'i love computers' without the quotes.
