Python导入问题 [英] Python import issue

问题描述

显然我只是不知道如何在Python程序中正确导入东西。我只是从语言开始，它与我以前的Java有很大不同。

So apparently I just don't know how to import things correctly in a Python program. I'm just starting with the language, and it's much different from the Java that I'm used to.

无论如何，主要问题是如何出错我正在导入包/模块/类，我似乎无法弄清楚它是什么。

Anyway, the main problem is that there's something wrong with how I'm importing packages/modules/classes and I can't seem to figure out what it is.

现在我的文件结构如下：

Right now my file structure looks like:

-Main Directory
 main.py
    -Person (Folder)
        __init__.py
        Person.py
        Student.py

现在我的main.py文件看起来像..

Right now my main.py file looks like..

from Person import Person
from Person import Student

if __name__ == '__main__':

    p = Person.Person("Jim", 20)
    print(p)
    s = Student("Jim", 20, "math")
    print(s)

我一直收到错误 TypeError：'module'对象不可调用

尝试将其更改为 s = Student.Student（Jim，20，Math）但是当发生这种情况时我最终会出现错误 TypeError：module .__ init __（）最多需要2个参数（给定3个）

Have tried changing it to be s = Student.Student("Jim", 20, "Math") but when that happens I end up with an error of TypeError: module.__init__() takes at most 2 arguments (3 given)

供参考，

Person.py:

Person.py:

class Person():    
    def __init__(self, name, age):
        self.name = name
        self.age = age

    def __str__(self):
        return "My name is {0} and I am {1}".format(self.name, self.age)

Student.py：

Student.py:

from Person import Person
class Student(Person.Person):

    def __init__(self, name, age, sub):
        Person.__init__(self,name,age)
        self.sub = sub

无论我对进口做什么，或者我似乎都有什么改变，这一切都让我一直都有错误。不知道在这一点上该做什么 - 也许我只是错过了向我展示的类和子类的创建，但我无法弄清楚要修复它。

No matter what I do to the imports or anything I can seem to change, it all keeps giving me errors. No idea what to do at this point - maybe I just missed the creating of classes and subclasses when it was shown to me, but I can't figure out anything to fix it.

推荐答案

main.py：

from Person import Person
from Person import Student

if __name__ == '__main__':

    p = Person.Person("Jim", 20)
    print(p)
    s = Student.Student("Jim", 20, "math")
    print(s)

student.py

student.py

from Person import Person

class Student(Person):

    def __init__(self, name, age, sub):
        super(Student, self).__init__(name,age)
        self.sub = sub

person.py

person.py

class Person(object):    
    def __init__(self, name, age):
        self.name = name
        self.age = age

    def __str__(self):
        return "My name is {0} and I am {1}".format(self.name, self.age)
