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.
