Hi, This is my frist post here. I am learning Python and Qt and am trying to understand a pecularity with object references. I think I get the integer part, but for floating point it seems like the caching/interning process works a little bit here and there:
1) Same object on command line >>> a, b = 5.0, 5.0 >>> id(a), id(b) (11140648, 11140648) 2) Different object on command line >>> a = 5.0 >>> b = 5.0 >>> id(a), id(b) (11140616, 11140600) 3) Same object in script When running the last assignments for the float objects in a script (point 2) above, one line per assignment), it is cached again and the variables refer to the same object. Why is it different on a command line and in a script? How can you know when you create a new object or not, are there any rules? Thanks for a great forum. Regards, Bjorn
