The answer is that you can't. Python is not low-level like c/c++ - it does not provide APIs to do so. – Nir Alfasi Jun 13 '19 at 23:06

1You can't change a string in place, let alone reverse it. – Mikael Jun 13 '19 at 23:08

Python `str` objects are immutable. – juanpa.arrivillaga Jun 13 '19 at 23:12

1When asked this question in Python/Java where it is not possible to reverse a String in place the *"String"* will usually be provided to you as array/list of characters so it is possible: https://repl.it/repls/CornyBuzzingConferences – Sash Sinha Jun 13 '19 at 23:24

Python strings are immutable, which means you can't really change it. There's no way you could reverse it in-place.
Obviously, you could reassign the same variable to it, but this is not an in-place change as you asked for:
str = 'reverse'
str = str[::-1]
