R has the function edit() which allows the editing of the definition

In general, no. In general, it is not possible since the definition may
not be in Python. (The equivalent must be true in R also.)
In a decent Python IDE, like IDLE, that allows one to enter, retrieve,
and edit complete statements, then yes for function definitions entered
in the same session. It is also possible to edit multi-line code
line-by-line in the standard REPL, but it is more painful and error prone.
One can monkey-patch an edited function into an imported module written
in Python. The original code can be copied from an editor and pasted
into the REPL.
