/* JavaDoc above */
def inconsistentComments(){
""" Python docstrings below """
}

😂

when it's longer than one line, explaining more than the following line, or explaining what the following line does, then above.

when it's a bit of additional info for the line of code, then next to it:

position += orientation * speed * deltaTime; //deltaTime to make it go brrr framerate-independently

Comments are always above or inline. Documentation blocks vary in languages but are generally above the definition.
Perl POD is often below all the code.

Actually would be interested what you comment?
😅

`def inconsistentComments() {
...
}`

o.o what language is this? Some kind of Python hybrid with a C-like?
