Python: load variables in a dict into namespace

Consider the Bunch alternative:

class Bunch(object):  def __init__(self, adict):    self.__dict__.update(adict)

so if you have a dictionary d and want to access (read) its values with the syntax x.foo instead of the clumsier d['foo'], just do

x = Bunch(d)

this works both inside and outside functions -- and it's enormously cleaner and safer than injecting d into globals()! Remember the last line from the Zen of Python...:

>>> import thisThe Zen of Python, by Tim Peters   ...Namespaces are one honking great idea -- let's do more of those!

Rather than create your own object, you can use argparse.Namespace:

from argparse import Namespacens = Namespace(**mydict)

To do the inverse:

mydict = vars(ns)

This is perfectly valid case to import variables inone local space into another local space as long asone is aware of what he/she is doing.I have seen such code many times being used in useful ways.Just need to be careful not to pollute common global space.

You can do the following:

adict = { 'x' : 'I am x', 'y' : ' I am y' }locals().update(adict)blah(x)blah(y)
