Have a great bank holiday, folks. For any sad (or happy) Python programmers out there, here's a simple example of __getattr__ in use. I've got an object of type thingy with all its atributes held in a dictionary, but I wanted to access them as if each was a separate attribute. "I couldn't find a simple example elsewhere, so I wrote one"
"""Using a dictionary as an attribute handler in Python"""
class thingy:
def __init__(self,indict):
self.stuff = indict
def __getattr__(self,which):
return self.stuff.get(which,None)
about = {"colour":"blue", "type":"flipchart marker"}
markerpen = thingy(about)
print markerpen.colour
print markerpen.age
