Each package, module, class, function and method function owns a "namespace" in which variable names are resolved. When a function, module or package is evaluated (that is, starts execution), a namespace is created. So if you want to create a namespace, you just need to call a function, instantiate an object, import a module or import a package. For example, we can create a class called Namespace and when you create an object of that class, you're basically creating a namespace.
Example
In this class, you can also pass variable names to attach to the namespace, for example,
class Namespace: def __init__(self, **kwargs): self.__dict__.update(kwargs) args = Namespace(a=1, b='c') print args.a, args.b
Output
This will give the output:
1 c
