Passing a parameter to objects created by defaultdict
defaultdict, python
Solution
`defaultdict` takes any callable, so you can create a new function that doesn't take a parameter and returns an object instantiated with the parameter you want.
d = defaultdict(lambda: myobj(param1))
Another option is to use functools.partial, which creates a function with one (or more) of the parameters predefined:
import functools
d = defaultdict(functools.partial(myobj, param1))
Problem
I want to have a default dict that includes a parameter when it constructs a new object. Is this possible, is there a better way to do it? ``` defaultdict(myobj, param1) ``` then myobj: ``` class myobj(object): def __init__(self, param1): self.param1 = param1 ```
