Printing a list of objects of user defined class

Question

So I have a class, called Vertex.

class Vertex:
    \'\'\'
    This class is the vertex class. It represents a vertex.
    \'\'\'

    def __in         


        

Answer 1

If you just want to print the label for each object, you could use a loop or a list comprehension:

print [vertex.label for vertex in x]

But to answer your original question, you need to define the __repr__ method to get the list output right. It could be something as simple as this:

def __repr__(self):
    return str(self)
