Winner! Thanks all.
I want to make sure I understand what this line is doing:
> oldprint = print
Experimenting, I find this is not a rename because I can use both
function names. It looks it literally copies the function "print" to
another function called "oldprint". But now, I have a way to modify the
builtin funciton "print" by referencing oldprint. Without oldprint, I
have no way to directly modify print? For example, based on your post, I
tried:
def print(*args, **kw):
print(*args, sep='', **kw)
meaning print calls print (itself) with sep=''. But this failed and I
guess the reason is that it would keep calling itself recursively adding
sep='' each time? Thanks.
