Traceback (most recent call last):

NameError: name 'main_frame' is not defined
When I read about wx.Frame I see that the name parameter is the internal
reference name for the class so I thought the above was correct. When I
replace the name with the class name I get a different error:
Traceback (most recent call last):
File "./openEDMS.py", line 296, in <module>
top = MainFrame('openEDMS')
TypeError: __init__() missing 1 required positional argument: 'title'
I've looked at the 4.0.1 demo, a couple of tutorials, and the 4.0.2a API
at <https://wxpython.org/Phoenix/docs/html/wx.Frame.html> yet still do not
see my error. I need to learn what I've done incorrectly between the
wx.Frame initialization and referencing it so the module runs.

Your class is named MainFrame not main_frame.

reference name for the class so I thought the above was correct. When I

The TypeError is telling you the problem. Your class MainFrame takes two arguments in its __init__ method, parent and title. You've only passed one argument.
I thought the reference should be to the class name, not the internal
name. Thanks for confirming this.

arguments in its __init__ method, parent and title. You've only passed one
argument.
Then I'm not seeing the type error. The class __init__ method specifies
the title:
When you are calling MainFrame() you are instantiating a class, which will call the __init__ method. You are only passing a single parameter to MainFrame() but you have defined MainFrame's __init__ to have two parameters, parent and title. You have to pass both.
You might want to brush up on Python classes here:
See the documentation about the __init__ method.

In addition to the class name and init notes, you likely want to use top.Show() here if you actually want to show the frame instead of calling some non-existent top-level Show function.

Thank you. It's been a long time since I used wxPython and I've forgotten
much more than I realized.
Best regards,

I know your questions were answered, but I’m confused enough by this
statement that I’d like to explore it. You had this:
MainFrame IS the class name. That’s all Python knows. “main_frame”
is just a string that happens to be passed as a parameter to another
method call. The language doesn’t know anything about that. More,
that string won’t be seen until the class is instantiated, which can
only be done by using the Python class name.
The type error happens at the line where the error occurs:
top = MainFrame(‘openEDMS’)
This is just like calling a constructor in C++. It creates an
object, and calls the init method to initialize the object.
This is exactly the same as:
top = MainFrame.init( , ‘openEDMS’ )
Given that, you can see that you are missing the “parent” parameter
to your constructor.

but the type error is at the end of the module where there is no __init__

This is just like calling a constructor in C++. It creates an object, and

top = MainFrame.__init__( <empty object>, 'openEDMS' )
Given that, you can see that you are missing the "parent" parameter to
