Re: deleting an object

Please help. Questions based on snippet of code below.

Please post code that works. Use cut and paste.

1) when myTestCase is deleted, is just the pointer deleted or the
entire instance with all of its data and data structure deleted?

Have you read the manual section on the del statement?

2) What is the practice for deleted the object and recovering the
memory it occupies?

Most programs use del rather sparingly. Most temporary objects are
created within functions and get unbound automatically when the function
exits. If you need to guarantee release of external resources before
the program ends, make explict calls to .close methods of the instances
that connect to them. Actually memory recovery depends on the
implementation and version. I would not worry about this until you
really need to.

3) If delete is the way, what happens to
‘testUtils.utilFunction1()’ if it were instantiated in other classes
that have not been deleted yet?

Objects will not be destroyed while still reachable from code (in the
absence of a severe bug).

import testUtils
class testClass:
def __init__(self):
self.testList = list()
self.testDict1 = dict()
self.utils1 = testUtils.utilFunction1()

myTestCase = testClass()
delete myTestCase

Don't indent main body code.
Do use legal keywords.
