I understand this toy example:
lines = "this is a group\nof lines of\nwords"
def getlength(w): return len(w)
s = map(getlength, [word for ln in lines.split() for word in
ln.splitlines()])
(now s is [4, 2, 1, 5, 2, 5, 2, 5])
My question is whether there's any compact way to combine function
calls, like this (which doesn't work):
lines = "this is a group\nof lines of\nwords"
def getlength(w): return len(w)
def timestwo(x): return x * 2
s = map(timestwo(getlength), [word for ln in lines.split() for word in
ln.splitlines()])
I hope the question is clear enough. I have a feeling I'm ignoring a
simple technique . . .
lambda !
map(lambda x: timestwo(getlength(x)), ...)
