I am week on functional programming, and having hard time
understanding this:
class myPriorityQueue:
def __init__(self, f=lamda x:x):
self.A = []
self.f = f
def append(self, item)
bisect.insort(self.A, (self.f(item), item))
............
now I know we are inserting items(user defined type objects) in list A
base on sorting order provided by function A.
but what I don't understand is bisect command
what does bisect.insort(self.A, (self.f(item), item)) doing
isn't it is returning truple of (self.f(item), item)).
why it is not
biset.insort(self.A, item)
A.sort(f)
thanks for your comments
