Objects in python have reference count which basically means the amount of places an object exist in. Using del<\/code> removes one reference to the object (it does not force delete it). __del__<\/code><\/a> is then called when 0 references are left. You may create a new reference to the object and this way prevent it’s deletion like so:<\/p>\n

class obj:\n    def __del__(self):\n         global _ref\n         _ref = self\n         return\n<\/code><\/pre>\n
This will prevent the deletion of the object by creating a global reference.
\nKeep in mind it is not suggested to do so as it will prevent the garbage collector from working correctly.<\/p>\n
UPDATE:<\/strong><\/p>\n
In case you are using a list, you should convert it to an immutable object such as a tuple<\/code> in order to prevent changes like deletion as so:<\/p>\n
mylist = [obj1, obj2, obj3, obj4 ....]\nmylist = tuple(mylist)\n<\/code><\/pre>\n<\/p><\/div>\n
<\/div>\n<\/div>\n
