Is it possible to decorate a predefined function.

Question

How could one decorate print() for example

Answer 1

Closest I found online seems to recommend (because "no, decoration happens at 'def' time") wrapping the functions and some other weirdness [link 1].

So...I took the method we've both recently used...overriding the builtin with a new name...then decorators work fine:

^^^ Here, the print() function auto-repeats itself twice and auto-clocks that duration (I include an arbitrary delay), using decorators, without modifying the print line itself.

For ideas, I also looked at "tracers" (sys.settrace) -- try traceMe("print") at line 36:

...and late binding [link 2] "In Python, you can rebind any function..."
