Strings, Loops
A simple method for compressing a string is to reduce the amount of repeated information by recording characters and the number of times they repeat (if any).
For example, the compressed version of 'aabbaabb' is 'a2b2a2b2' because
'a' appears twice, followed by 2 'b's, 2 'a's, and 2 'b's.
The compressed version of 'abc' is just 'abc'. That’s because
'a1b1c1' is twice as long as the original string, which would make our
compression algorithm pretty useless.
Here are some more examples:
'Hello, world! Cows go moooo...' => 'Hel2o, world! Cows go mo4.3'
'balloonicorn' => 'bal2o2nicorn'
Write a function that takes in a string and returns a compressed version of that string. Your string will only contain non-numeric characters — that is, it will only contain letters, whitespace, and punctuation.
We’ve provided compress-string.py which contains tests and a function stub for you to complete.
