Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.

Nice, no dubplicates of the conditions
Hi @Rockkley.
Lambdas are anonymous callable objects. If you want call it later, you must use a variable, no other choice to do that. And here (in codewars) if there no name, unit test cannot check the solution.
For your information, in python, a
def
(and so, a fonction) defined like that create a variable:The variable created is
foobar
, the proof, you can do that:It's the aim of the mechanism under the concept of decorators.
If you prefer i can use these solutions instead of lambda, the solution will be acepted:
I know that lambda is anonymous function, and there's no need to create variable for lambda, but here we need to meet the interface requirements. Requirement here is that
check
is callable.In real world I would not create function for this one liner, that's why I'm showing solution with
lambda
.variable "check" holds the function. and ambda describes the oneliner function.
mult = lambda a,b:a*b
is the same as
def mult(a,b):
return a*b
What do you mean? Do you know how lambdas work? Do you know you can copy the code and make trials on your own to understand how it works? On your own computer, or just here, by clicking on
Fork
just below any solution.Why creating a variable for lambda?
