So and if I have code like this:
f = lamda x:x for g in some_iter:
f = compose(g,f)
Do you still think that one should use a named function in this case?
Yes. If you really don't like taking two lines, Python still allows you to write this as:
def f(x): return x
for g in some_iter:
f = compose(g, f)On the other hand, if you really love FP enough to write this kind of code, shouldn't you be using reduce istead? ;) I'm horrible with reduce, but something like:
def identity(x):
return x
f = reduce(compose, some_iter, identity)or if you want to use lambda (note that my complaint about making an named function with the anonymous function syntax doesn't apply here):
f = reduce(compose, some_iter, lambda x: x)
Not sure if the order of composition is right here, but you get the idea.
