如何访问模块中类方法内的本地对象？

Question

I was trying to access a local variable inside of a class that is in a module. So Far I can only access it while doing the call inside the module itself and not as a import.

this is my only successfull attempt to retrieve "coisa". is there a easyer way to call it?

class Hello():
    def MyObject():
        coisa = 22
        return coisa

link = Hello.MyObject()
print(link)

But this is the situation I am trying to actually overcome. Importing a module and access a object inside it class and function. Main.py

import Module

link = Module.Hello.MyObject()
print(link)

Module.py

coisa = "67"
class Hello():
    def MyObject():
        coisa = "22"
        return coisa

Answer 1

You cannot acces coisa var directly if it is defined in your function as it is a local variable.

In an hypothetic case where coisa would be defined outside your function, you could access it directly. For example :

Module.py

COISA = "67"

class Hello():
    def MyObject():
        coisa = "22"
        return coisa

You can access COISA from your external code by calling it directly. Note the Uppercase naming style, conforming to PEP-8 naming convention for constants.

import Module

link = Module.COISA 
print(link) # Will print 67

Or you can access coisa, defined locally in your function, in Lowercase naming style, this way. You have to return the variable value in your function as it is a local variable for your function.

import Module

link = Module.Hello.MyObject()
print(link) # Will print 22

EDIT

Note that you can also directly access to a variable defined in your class. For example :

Module.py

COISA = "67"

class Hello():

    coisa_in_my_class = "85"

    def MyObject():
        coisa = "22"
        return coisa

You can call coisa_in_my_class easily :

import Module

link = Module.Hello.coisa_in_my_class
print(link) # Will print 85

Answer 2

I don't really understand the question but I think you mean a staticmethod so try this

class Hello():
    @staticmethod
    def MyObject():
        coisa = "22"
        return coisa

Then you can

import Module

link = Module.Hello.MyObject()
print(link)  # 22
