I've heard that the reason why python uses reference counting rather
than tracing collector is because python cannot determine the root set
for its various C extensions.
But provided that BDWGC(full name: Boehm-Demers-Weiser conservative
garbage collector) is conservative --- can be used for C, and
given i = 0,
I know i = i + 1 and i += 1 are all correct
but when I type:
>>> i++
the interpreter replies:
File "", line 1
i++
^
SyntaxError: invalid syntax
so I get the idea that suffix ++ is invalid in python
but when I input:
>>> ++i
and the interpreter replies
0
Don't you think it
