Several of the doors in ye old house were sticking at the top at the latch end. The door was angled too high (or the door frame top was drooping). My solution, in each case, was to use a chisel to deepen the lower hinge seat on the door frame. This allowed the bottom of the door to swing towards the hinge side, bringing the top away from the frame. I could have added shims to the top hinge too. Indeed, for one of the doors I added shims to the top hinge, chiseled away the lower hinge AND chiseled away a bit of the top corner.
Python's context managers are a very neat way of handling code that needs a teardown once you are done. Python objects have do have a destructor method ( __del__ ) called right before the last instance of the object is about to be destroyed. You can do a teardown there. However there is a lot of fine print to the __del__ method. A cleaner way of doing tear-downs is through Python's context manager , manifested as the with keyword. class CrushMe: def __init__(self): self.f = open('test.txt', 'w') def foo(self, a, b): self.f.write(str(a - b)) def __enter__(self): return self def __exit__(self, exc_type, exc_val, exc_tb): self.f.close() return True with CrushMe() as c: c.foo(2, 3) One thing that is important, and that got me just now, is error handling. I made the mistake of ignoring all those 'junk' arguments ( exc_type, exc_val, exc_tb ). I just skimmed the docs and what popped out is that you need to return True or...
