Python, lambda, find minimum
- by qba
I have foreach function which calls specified function on every element which it contains. I want to get minimum from thise elements but I have no idea how to write lambda or function or even a class that would manage that.
Thanks for every help.
I use my foreach function like this:
o.foreach( lambda i: i.call() )
or
o.foreach( I.call )
I don't like to make a lists or other objects. I want to iterate trough it and find min.
I manage to write a class that do the think but there should be some better solution than that:
class Min:
def __init__(self,i):
self.i = i
def get_min(self):
return self.i
def set_val(self,o):
if o.val < self.i: self.i = o.val
m = Min( xmin )
self.foreach( m.set_val )
xmin = m.get_min()
Ok, so I suppose that my .foreach method is non-python idea. I should do my Class iterable because all your solutions are based on lists and then everything will become easier.
In C# there would be no problem with lambda function like that, so I though that python is also that powerful.
