Python list to store class instance?

Given a python class class Student(): and a list names = []; then I want to create several instances of Student() and add them into the list names,

names = [] # For storing the student instances
class Student():
    def __init__(self, score, gender):
        self.score = score
        self.gender = gender

And now I want to check out the scores of all the male students, can I do it like this?

scores = []
for i in names:
    if i.gender ==  "Male":
        scores.append(i.score)

My question is: How to create a list that can (if could be done by any statement) store the instance of Student? Or rather, when I write names = [], how could I state every element in names is an instance of Student so that I can use the attributs of this element despite python is weak type? I hope I made myself clear ;)

Can I write like:

    for i in range(len(names)):
        student = Student()
        student = names[i]
        if student.gender == "Male":
            # Whatever

I guess not...
