Hi
I am looking the relationship between some classes
from the enum module
from enum import EnumMeta, Enum
class Color(Enum):
pass
type(EnumMeta)
EnumMeta.__bases__
(,)
so EnumMeta is a metaclass, it is an instance of type
and inherit from type too.
type(Enum)

It should have come with Python. Try it - you should be able to just

_siftdown function breaks out of the loop when the current pos has a valid

but _siftup function is not implemented in that fashion, if a valid subheap
is given to the _siftup, it will bring down the root of sub heap and then
again bring it up to its original place.

As an attempt to answer your original question, Python doesn't explicitly
mark a module as done. It does keep imports cached in sys.modules, though.
The behaviour you describe where later imports get the same module object
is driven by that cache.
There are cases, such as cyclical imports, where t

Hallow,
I try to open a .py file (attached), but what I get is a windows DOS window
opening and closing in a couple of seconds. Ran repair of the program, nothing
happened.
I cannot see error messages and don't know where to look for ones.
Would appreciate your piece of advice.

Hi
I am an computer science engineer. I downloaded the python version
3.5.1.amd64 and just python 3.5.1. The problem is when I install the program
setup is failed and showing 0*80070570-The file or directory is corrupted and
unreadable. I install the newest visual c++ redist and still same.
I think it has to be with some functions that I think they are defined on the
"forked" processes and maybe they don't, if I create a class on the new process
it should have all the defined functions than the original right?

The short version: How CPython marks a module as being fully imported, if it

The __bases__ property is defined by the metaclass, "type". dir() of a
