How do I create instances of a class within that class?-CodePudding

So we have two classes: Test and TestManager. Every Test object should have its manager, instantiated on its __init__ function. Also, in order to create a TestManager object, you need to pass a Test instance to it.

How can we do that? I have this, but doesn't work:

class SubTest:
    def __init__(self, test):
        print(test.getText())

class Test:
    def __init__(self):
        self.text = "Hello world!"
        SubTest(Test) # In Java this would be something like 'new SubTest(this);'

    def getText(self):
        return self.text

Test()

Thanks!

CodePudding user response：

When passing a Test to SubTest, refer to the class as 'self', meaning your code should look a little something like this:

class Test:
    def __init__(self):
        self.text = "Hello world!"
        SubTest(self) # Passing self, instead of 'Test'

And your full code like this:

class SubTest:
    def __init__(self, test):
        print(test.getText())

class Test:
    def __init__(self):
        self.text = "Hello world!"
        SubTest(self)

    def getText(self):
        return self.text

Test()
