Yea. I got it. It was a new information for me. A module in a package can
import its own mother package to call the variables in __init__.
Is it funny or an extraordinary feature? Anyway. I felt it as something weird.
Guido should have done it something like how 'self' behaves in classes.

Hi,
If you store the variables in __init__.py, you can import them from the
package. So in your case suppose __init__.py contains:
a = 10
b = {1 :"Hello", 2: "World" }
Than if you import my_package, you can access the variables as follows
(interactive IPython session):
In [1]: import my_package
In [2]: my_pack
my_package my_package/
In [2]: my_package.
my_package.a my_package.b
In [2]: my_package.a
Out[2]: 10
In [3]: my_package.b
Out[3]: {1: 'Hello', 2: 'World'}
In [4]:

Accessing variables in __init__.py
my_package/ __init__.py my_module1.py my_module2.py variables.py I want to define common variables in __init__.py and use the namespace in my_module1.py or my_module2.py. Defining it is not a problem. How can call it from my modules? If I define them in a module (say, variables.py), I can call them by importing variables.py in other modules. How can it be done if I define it in __init__.py? It may be a silly query as I am newbie in Python. But, I would be grateful to get help. -- http://mail.python.org/mailman/listinfo/python-list
