The file animals.txt has a list of animals, each written on a new line. For example:
rabbit
cat
turtle
Create a new file, animals_new.txt, where those animals are written on a single line and separated by a whitespace.
Don't forget to close all files!
Tip: The fact that animals in the first file are written each on a new line means that each string in the file, except for the last one, ends with '\n'. To get rid of \n, you can use either str.rstrip() or str.replace() methods.
