Not bad, but you didn't reverse in place and didn't handle extra spaces in the output. Otherwise not bad. Check out my comments and let me know if you have questions.

You are doing my_sentence.split which creates a new array of equal size to the string. So... This is O(n) space complexity.
You were asked to do this in place.

This works, but you assume each word is separated by one space. That's not necessarily true.

Since you do .split this has space complexity of O(n).
