Bad example :)
Most simple uses of lambda like this can be substituted with functions
from the operator module:
import operator
formulas = {
'sum': operator.add,
'subst': operator.sub,
'mult': operator.mul,
'pow': operator.pow
}
- flavio81 9y agoI thank you for this example. If the operator definitions are not trivial and you want to keep them well mantained, then your example is very good. However, what I meant was that for fast, quick coding, if your 'operator' function is really simple, then lambda fints perfectlu. I know the Zen of Python says: "There should be one—and preferably only one—obvious way to do it", but i don't align to that principle. I think there should be more than one way to do something, and one should choose one that fits the best.
