Github For Mercurial User

You are a Mercurial user and have little experience with Github. You are required to publish your Mercurial repository on Github. The good news is, you can do it without parting with Mercurial. There are bridges between Git and Mercurial. The one we are going to talk about today, is hg-git.

Let's start demonstrating our solution.

Step 1: Create a mercurial repository somewhere. I do it on Bitbucket. We'll call this our canonical repository. Clone the repository.

Access Dictionary Keys As Object Attributes

You access Python dictionary keys using the syntax:

my_dicy[my_key]

For example:

>>> my_dict = {'food': 'idly'}
>>> my_dict['food']
'idly'

Sometimes, you might want to access the dictionary keys using:
my_dict.my_key
syntax. If you do this is what happens:

>>> my_dict.food
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'dict' object has no attribute 'food'

How can you solve this? Easy.

$ pip install attrdict
