backquote

[Olaf Meding]

Is `object` (using backquotes) the same as saying str(object)? Trying
to understand how backquotes work. Thanks for your help.

`object` is equivalent to repr(object).

Is this syntax one of those vestigial short-cuts that is on somebody's hit
list for future deprecation? To my eyes, `object` is more arcane than
repr(object) - why else would we be having this thread in the first place?

I believe so. It's scheduled for removal in Python 3.0 or at the heat
death of the universe, whichever comes first.

I suspect so, but not before Python 3.

see GvR's comments at:

http://python.org/doc/essays/ppt/regrets/5

He is recommending we drop `x` in favor of repr(x)

Indeed. Recently (current CVS) a patch was applied removing almost all
occurences of backquotes in the standard library, and they will be
removed in Python 3.0. I believe Guido regrets them.

It's the same as using "repr(objec t)".
