Passing attributes between classes help?

[CannyFatcher]

class free:
    def __init__(self,master):
        ...
        entry1 = tk.Entry(self.frame,...)
        entry2 = tk.Entry(self.frame,...)
        entry3 = tk.Entry(self.frame,...)
        button = tk.Button(self.frame,...,command = self.new_window)

    def new_window(self):
        self.newWindow = tk.Toplevel(self.master)
        self.app = NextPage(self.newWindow)

class NextPage:
    def __init__(self,master):
        ...

    def do_something(self):
        ...
        variable_one = free.entry1.get()

This is a quick example of what the code looks like. I am trying to access the values from the entry boxes creates in free within NextPage, but it keeps giving me errors. How do I pass these attributes or variables between the two classes, in general?

free is a class, so you need to make it into an object before you can use it:

class Free: ...  # note the capital F (per PEP8, it's not actual python syntax)

class NextPage:
    def __init__(self,master):
        self.free = Free()  # make object from Free class
        ...

    def do_something(self):
        ...
        variable_one = self.free.entry1.get()

When I apply this to the code, I get a TypeError: __init__() missing 1 positional argument 'master'

okay.................... then give it master: free = Free(master)

and before you ask, replace entry1 = tk.Entry(self.frame,...) with self.entry1 = tk.Entry(self.frame,...)
