The other day I wrote a lambda akin to the following:
fetch = lambda x: myDictionaryVariable.get(x, "")
But now I just learned that to a point you can separate python statements with a ; instead of a newline and then learned that you can do simple statements on 1 line even with the colon. So I realized I could also write this:
def fetch(x): return myDictionaryVariable.get(x, "")
Not that I'm using the ; here, but if I needed to I could, and thusly provide even more functionality for my 1-line function. I could write:
def strangeFetch(x): y = "unicorn"; return menu.get(x, y)
So why do I need lambdas at all? Why are they even a part of python? In view of this, what do they add?
