python - What are some Pythonic ways to share variables with objects defined in a module? -

-

I am creating a module where there are many different objects, which need to be controlled by multiple variables.

If it was, then I would pass the objects into an indicator / variable / object, which I want to see, the variables in the application need to be changed, and the objects in the module will "see" new Values.

In the module foo.py: 

  square foo (object): def __init __ (auto, varToWatch): self.varToWatch = varToWatch def DoSomething (print): Print Self.varToWatch

In the application, bar.py: 

  import foo x = "before" y = foo.foo (x) y. This definitely does not work, because what does the original value of x (or the context of x's original value) do? ) Is stored in Y  
 Therefore, I will try ...  
     
  1.  Pass a global name, and name the global name by foo. None, because in place of the global application, not in the module  
  2.  To make a global use in Fu namespace, but I do not know how to address that location by variable name, instead of importing it * is importing from foo * it is painful to change Will happen.  
  3.  Make a dictionary in the module and pass the objects in the module to the name of any key in the dictionary. Manipulate the content of the dictionary from the application. Actually, I'm defining a new global space and sticking the variable in it. I do not see any reason that this will not work, but it seems unclear to me, do I just have to be unfamiliar with Python?   
     I am not getting such a beautiful solution, which is used to see me easily with a dragon, so I suspect that I am missing something  
     Suggestions?  
     TIA, - Tim.   
     
     
     How to insert control variables in a separate module - say,  Settings < / Code> - and a different  import settings ? You can then see  settings.bar  and  settings.quux  from  foo import * to  to close your main namespace. ;-) You can also use a global object to store your settings, mostly with the same effect. 
     
     Of course, with such problems, you will be surprised that a  import Foo  for the reconstruction of things will not help things long ... knowing the problem It is impossible to do without justice, however, so I will give you this problem.

oracle - The fastest way to check if some records in a database table? -

-
I have a big table to work with. I have to see that there are some records whose parent_id is equal to my passing value. Currently I do this by implementing "my_table using select count (*) where parent_id =: id"; If the result> 0, it means that they exist. Because this is a very large table, and I do not care what the actual number of records present, I just want to know if it exists, so I think count (*) Bit is disabled. How do I apply this requirement most quickly? I'm using Oracle 10. # Tips for Hibernation & amp; Tricks It suggests writing in such a way: Integer number = (integer) session .createQuery ("Select Count (*) to ...."). UniqueResult (); I do not know what is the magic of the unique rule? Why does it fast? To compare, select "1 from mytable where parent_id = passId and rowrum", which is more efficient? If you are not interested in the number of records, then there is an EXISTS query one: Select 'y'
