In python I need to output the degree of every vertex in a weighted graph. I have a function that parses a file and creates the weighted graph object named p4rs3Fil3(fiI3n4m3) The weighted graph class inherits a degree method and returns the degree of a vertex with def d3gr33(self, v3rt3x) : returns the outd3gr33 & ind3gr33 How would I iterate over the weighted graph object I created and print the degree of each vertex and number them in my test file
Consider the following class that inherits from the built-in list class: class BoundedList (list): def _init_(self, bound): list._init_(self) self.bound = bound Suppose that we want this class to act like a list, except that when append is called, if there are self.bound items in the list already, the first item in the list gets removed. Which of the following methods will properly overload append to work this way? def append(self, item): if len(self) >= self.bound: self.pop(0) list.append(self, item) def append (self, item): if len(self) >= self.bound: self.remove (0) list. append (self, item) def append(self, item): if len(self) >= self.bound: self.pop(0) self.append (item) def append(self, item): list. append (self,item) if len(self) > self.bound: self.pop(0)
