what the fuck is a lambda

[queue]

it defines a basic anonymous function (called a lambda function), useful for when you ever need to return a function like this:
############################################
def createAdder():
    return lambda a1, a2 : a1 + a2 # a1 and a2 are the arguments

adder = createAdder() # returns the lambda function
print( adder(5,5) ) # --> 10
############################################
it does look a little similar to the c ternary but is completely different
