[Python3][Resolved] NameError: name 'Male' is not defined, module & inheritance

Source code

The files are in a package, named person.

male.py

class Male():
    sex_chromosomes = "XY"
    def __init__(self):
        self.type = "male"
    def say(self):
        #super().say()
        print("I am a male")

man.py

from person import male

male = Male()
male.say()

Problem

Male() is a class in module male, you can call the class in module by dot

man.py
from person import male

male = male.Male()
male.say()
