title: How might I resize the window of my tkinter program?
body: <p>Here is an example of my code</p>
  
  <pre><code>import tkinter as tk
  from tkinter import ttk
  class gui_programming(tk.Tk):
      def __init__(self, *args, **kwargs):
          tk.Tk.__init__(self, *args, **kwargs)
          container = tk.Frame(self)
          container.pack(side="left", fill="both", expand=True)
          container.grid_rowconfigure(0, weight=1)
          container.grid_columnconfigure(0, weight=1)
          self.frames = {}
          for F in (StartPage, Page1):
              frame = F(container, self)
              self.frames[F] = frame
              frame.grid(row=0, column=0, sticky="nsew")
          self.show_frame(StartPage)
      def show_frame(self, cont):
          frame = self.frames[cont]
          frame.tkraise()
  ##number 1
  class StartPage(tk.Frame):
      def __init__(self, parent, controller):
          tk.Frame.__init__(self, parent)
          c = tk.Canvas(self, bg="red", width=75, height=100)
          c.place(x=0, y=0)
          butt0 = ttk.Button(self, text="Next.",  command=lambda:controller.show_frame(Page1))
          controller.bind("1", lambda x: controller.show_frame(StartPage))
          controller.bind("2", lambda x: controller.show_frame(Page1))
          controller.bind("3", lambda x: controller.show_frame(Page2))
  class Page1(tk.Frame):
      def __init__(self, parent, controller):
          tk.Frame.__init__(self, parent)
          lambda x: gui_programming().geometry("75x100+10+10")
          c = tk.Canvas(self, bg="blue", width=300, height=200)
          c.place(x=0, y=0)
  
  app = gui_programming()
  app.geometry("75x100+10+10")
  app.mainloop()
  </code></pre>
  
  <p>So, how should I go about changing the window that each class appears in from 75x100 to something else, is there a command to resize the window? I would like to be able to resize it for each class.</p>
