Useful python trick of the day: dict.get()

How often in Python have you written something like:

d[k] if k in d else "Default"

Admittedly this has gotten a lot shorter since the inclusion of ternary operators in Python, but did you know that Python provides a get method for dictionaries that allows you to provide a default?

d.get(k, "Default")

I only found out today when reviewing code. Exciting!
