I'm not seeing the error source in a small tkinter module I'm testing.

The module code:
-----------
import tkinter as tk
from tkinter import ttk

import common_classes as cc

class ConactNameInput(tk.Frame):
def __init__(self, parent, *args, **kwargs):
super().__init__(parent, *args, **kwargs)
# A dict to keep track of input widgets
self.inputs = {}

self.inputs['Last name'] = cc.LabelInput(
ContactNameInput, 'lname',
input_class = ttk.Entry,
input_var = tk.StringVar()
)
self.inputs['Last name'].grid(row = 0, column = 0)
#
self.inputs['First name'] = cc.LabelInput(
ContactNameInput, 'fname',
input_class = ttk.Entry,
input_var = tk.StringVar()
)
self.inputs['First name'].grid(row = 0, column = 1)

okay_button = tk.Button(self, text="OK",
command=self.ok)
okay_button.pack(side=tk.LEFT, padx=(20, 0), pady=(0, 20))

cancel_button = tk.Button(self, text="Cancel",
command=self.cancel)
cancel_button.pack(side=tk.RIGHT, padx=(0, 20), pady=(0, 20))

def okay_button(self):
pass

def cancel_button(self):
Quitter()

def get_last_name(self):
pass

def get_first_name(self):
pass

class NameApplication(tk.Tk):
def __init__(self, *args, **kwargs):
super().__init__(*args, **kwargs)
self.title("Contact Name")
self.geometry("800x600")
self.resizable(width = False, height = False)
ContactNameInput(self).grid(row = 0, column = 0, sticky=('EWNS'))
self.columnconfigure(0, weight=1)

if __name__ == '__main__':
app = NameApplication()
app.mainloop()
----------

The python error traceback:
----------

I'm not correctly placing the NameInput class in the NameApplication frame.
What have I missed?

Presuming this is a cut&paste of the actual code...

> ContactNameInput, 'fname',

> ContactNameInput(self).grid(row = 0, column = 0, sticky=('EWNS'))

.... please compare the spelling!

This works if a tk.labelframe is where the widget is placed. In my case, as
MRAB taught me, the proper syntax is
self,'lname'...
self.'fname'...

Thanks, Dennis,

There is a comma (U+002C) here ...

> self.'fname'...

And a dot (U+002E) here.

I don't think this is correct.

I would also recommend to always add a space after a comma.

That was a typo when I wrote the message. And I usually add a space after
commas and surrounding equal signs, all for easier reading.

Thank you,
