Dear All,
Thanks your answers about why I can't redifne the print.
I just wanted to play with Python dynamic possibilities.
I wanted to replace function in a loaded module instead of create an
inherited class and using that.
It was easier to try it with print.

In the general case, this is difficult, and "solving" it might be worse

No precisely because the print statement is a statement (or more accurately
a command) not a function.
