[Tkinter] Grids

[menator01]

I been following the tutorial here on grids making my own little project and have ran into a snag.
I have a menu of button across the top and can't seem to get all buttons correct with and sizing.
I am posting all code but will point out problem area. Any help with what I'm doing wrong would be great. Thanks

        self.master = master

        self.main_frame_style.configure('MainFrame.TFrame', background = 'slategray')
        self.main_frame = ttk.Frame(self.master, style = 'MainFrame.TFrame')
        self.main_frame.grid(column = 0, row = 0, sticky = ('n','s','e','w'))
        # self.main_frame.grid_columnconfigure(1, weight = 1, uniform = 'john')

        self.header_style = ttk.Style()
        self.header_style.configure('Header.TLabel', background = 'slategray3', relief = 'groove', anchor = 'center', padding = (2,2,2,2))
        load = Image.open('/home/johnny/Desktop/cookbook_logo.png')

        self.header = ttk.Label(self.main_frame, image = render, style = 'Header.TLabel')

        for letter in letters:

def main():
    root = tk.Tk()
    root.title("Johnny's CookBook")
    root.configure(borderwidth = 5, highlightcolor = 'slategray', highlightbackground = 'slategray', highlightthickness = 4)
    window = MainWindow(root)
    root.mainloop()

if __name__ == '__main__':
    main()

Sorry. I should have posted in the GUI section.

I got it to work using this in the parent

for i in range(26):
            self.main_frame.grid_columnconfigure(i, weight = 3, uniform = 'john')

The lack of a simple to use geometry is the reason I never use tkinter any more except for very simple applications.
However this is one of the best tutorials on the subject: https://www.python-course.eu/tkinter_lay...gement.php
