Python module variables -


in root of application have app_db.py file sets variable. in app/models/models.py try 

from app_db import *

and try access variables, gives error variable not defined. app/models contains init.py file , models.py file. doing wrong? app_db.py file simple

if os.environ.get('database_url') none:     sqlalchemy_database_uri = 'postgresql://mfrtdskrujqfer:tikrp25zsl7w3mqtrw0@ec2-184-78-175-240.compute-1.amazonaws.com:5432/dev03fouea9lm' else:     sqlalchemy_database_uri = os.environ['database_url']

if going from package import * things available must listed in package/__init__.py files __all__ entry.

if from package import (name1, name2,...) not have unless names prefixed underscores, (see pep8 section on name mangling).

better still of course use import package , access package.name1, etc.

php - Accessing static methods using newly created $obj or using class Name -

see class definition below: i using 5.3.9 version of php class a{ static function ab(){ echo "static function ab<br>"; } public function xy(){ echo "public function xy<br>"; } } $obj = new a(); $obj->ab(); a::ab(); both functions call give same output without error static function ab static function ab how possible static method can called class object? because static method calls using class name only?! now difference between accessing these 2 ways call static method ? referring php.net website declaring class properties or methods static makes them accessible without needing instantiation of class. property declared static can not accessed instantiated class object (though static method can). a big difference is because static methods callable without instance of object created, pseudo-variable $this not available inside method declared static. refer page php.net/manual/en/
