Thanks for the link explaining a bit more on lambas.

However, SoloLearn just has examples of taking 1 argument. The example from w3schools takes in multiple arguments which is a bit confusing for me to understand.

Answer 5

Also our lambda has just one argument, "a".
But it has also an unknown variable, "n", passed by function myfunc()

So mydoubler = myfunc(2) can be replaced with
def mydoubler:
return lambda a : a * 2

or even, instantiating the lambda,

def mydoubler(a):
return a*2

Answer 6

lambda is an anonymous function
