Python 3

Your task is to create a function that will take an integer and return the result of the look-and-say function on that integer. This should be a general function that takes as input any positive integer, and returns an integer; inputs are not limited to the sequence which starts with "1".

Conway's Look-and-say sequence goes like this:

Start with a number.

Look at the number, and group consecutive digits together.

For each digit group, say the number of digits, then the digit itself.

Sample inputs and outputs:

1 is read as "one 1" => 11 11 is read as "two 1s" => 21 21 is read as "one 2, then one 1" => 1211 9000 is read as "one 9, then 3 0s" => 1930 222222222222 is read as "twelve 2s" => 122
