Accessing dict keys like an attribute?

Question

I find it more convenient to access dict keys as obj.foo instead of obj[\'foo\'], so I wrote this snippet:

class AttributeDict(dict

As noted by Doug there's a Bunch package which you can use to achieve the obj.key functionality. Actually there's a newer version called

NeoBunch

It has though a great feature converting your dict to a NeoBunch object through its neobunchify function. I use Mako templates a lot and passing data as NeoBunch objects makes them far more readable, so if you happen to end up using a normal dict in your Python program but want the dot notation in a Mako template you can use it that way:

from mako.template import Template
from neobunch import neobunchify

mako_template = Template(filename='mako.tmpl', strict_undefined=True)
data = {'tmpl_data': [{'key1': 'value1', 'key2': 'value2'}]}
with open('out.txt', 'w') as out_file:
    out_file.write(mako_template.render(**neobunchify(data)))

And the Mako template could look like:

% for d in tmpl_data:
Column1     Column2
${d.key1}   ${d.key2}
% endfor
