And is there a way to get the refcount of an object within Python? I'd
like to test if the refcount is correct.
sys.getrefcount(obj)
Good to know. When I run
- ------------------- test.py ----------------
from _test import *
import sys
def test_my_array():
a = A()
print 'a.my_array=',a.my_array
print 'sys.getrefcount(a)=',sys.getrefcount(a)
print 'sys.getrefcount(a.my_array)=',sys.getrefcount(a.my_array)
if __name__ == "__main__":
test_my_array()
- ------------ end test.py -------------
I get the output
- ----------- output -------------
wal...@wronski$ python test.py
a.my_array= [ 1. 2. 3.]
sys.getrefcount(a)= 2
sys.getrefcount(a.my_array)= 2
- ----------- end output --------
Ermm, is that good?
I expected that the refcount would be 1 and not 2.
When you call getrefcount, the argument becomes another reference, so
there are two references.
http://docs.python.org/library/sys.html#sys.getrefcount
sys.getrefcount(object)
Return the reference count of the object. The count returned is
generally one higher than you might expect, because it includes the
(temporary) reference as an argument to getrefcount().
