I am trying to make a gui full screen. Is working as full screen but i am not able to do the followings :
1 - first row (row 0) to be scaled to max width of screen
2 - on row 1, the first and last column have fixed width and stay on left and right of the screen (this is working)
3 - the empty labels between buttons to be on the center
4 - the 2 buttons to be center aligned in left and right
This is my code till now:

As mentioned in the comments, you simply need to set your root window resizable method to false. In your case it is the SeaofBTCapp class.
For Example:
import tkinter as tk
LARGE_FONT= ("Verdana", 12)
class SeaofBTCapp(tk.Tk):
def __init__(self, *args, **kwargs):
tk.Tk.__init__(self, *args, **kwargs)
self.resizable(False,False) # <------------------- added this

container.pack(side="top", fill="both", expand = False)
container.grid_rowconfigure(0, weight=1)
container.grid_columnconfigure(0, weight=1)
self.frames = {}
for F in (StartPage, PageOne, PageTwo):
frame = F(container, self)
self.frames[F] = frame
frame.grid(row=0, column=0, sticky="nsew")
self.show_frame(StartPage)

I am VERY new to coding/Python, but basically I am trying to move a button and label around using .grid, however, the button and label in the StartPage class just won't move to where I ask (or even at all).
Everything in the BMR class works fine (although the positions you see aren't the final positions, I was just checking).
What is the difference? Why do they not appear at the same position if I give the same details in both classes?

I understand this is how you wish to position the label and the button.
Pleaase see the comments. You can edit the value for the width property and make it suitable for your frame.
I have tried grid and place and it will not move the buttons to the place i want them. i don't know if its caused by fill which is stoping it from moving
the buttons are located in class mem
I want to also put the 'Quit' button on the top right of the window
if possible
which is also located in class mem

The easiest way is to create another Frame to store your next and back buttons, and use grid to align them side by side:
class mem(tk.Frame):
def __init__(self, parent, controller):
tk.Frame.__init__(self, parent)
self.controller = controller
self.configure(background = "white")
label = tk.Label(self, text="9929", font=(18))
label.pack(side="top", fill="y", pady=15, padx=270)
#label.pack(fill="x") #you don't need to pack the label twice
f = tk.Frame(self) #create another holder frame
button1 = tk.Button(f,relief="solid",borderwidth=5, text="next", font=(18))
button1.grid(row=0,column=0)
button2 = tk.Button(f, text="back",borderwidth=5,relief="solid", font=(18))
button2.grid(row=0,column=1)
f.pack(side="bottom")
button3 = tk.Button(self, text="Quit", font=(18))
button3.pack(side="right", pady=50)
I am coding a program which will need functions to change labels and enter text into text boxes however I do not know how to do this with a new style of programming which I am using (Object Orientated). I have done the program before however I generated the frames using this code:
f = [Frame(root) for i in range(0,5)]
for i in f:
i.place(relx=0,rely=0,relwidth=1,relheight=1)
and then I put it all in one class which I ran however that was bad form so I am redoing it. My code so far is as follows:
import tkinter as tk
import datetime,time,os,sys
import sqlite3 as lite
from datetime import date
Title_Font= ("Times", 18, "underline italic")
unix = time.time()
time_curr = str(datetime.datetime.fromtimestamp(unix).strftime('%H:%M'))

If you try it out it works however it just has 3 different frames. How can I get a button in a frame to make a label say "Hello" in the frame after it is pressed?
I've modified one of your page classes to illustrate how it could be done. It involved adding a Label to hold the message, a Button to control it, and a function, called simply handler(), to call when the latter is pressed. It saves the widgets by making them attributes of the containing Frame subclass instance, self, so they can be easily referenced in the handler() function (without resorting to global variables).
class PageOne(tk.Frame):
def __init__(self, parent, controller):
tk.Frame.__init__(self, parent)
self.grid_columnconfigure(0, weight=1)
self.grid_columnconfigure(3, weight=1)
label = tk.Label(self, text="Page One!!!", font=Title_Font)
label.grid(row=1, column=1)
self.msg_label = tk.Label(self, text="")
self.msg_label.grid(row=2, column=1)
self.msg_button = tk.Button(self, text='Show Message',
command=self.handler)
self.msg_button.grid(row=3, column=1)
self.msg_toggle = False
bk2_menu = tk.Button(self, text="Back to Home",
command=lambda: controller.show_frame(StartPage))
bk2_menu.grid(row=5, column=1)
def handler(self):
self.msg_toggle = not self.msg_toggle
if self.msg_toggle:
self.msg_label.config(text='Hello')
self.msg_button.config(text='Clear Message')
else:
self.msg_label.config(text='')
self.msg_button.config(text='Show Message')

I'm making a multiwindow GUI in tkinter and I want to change the backgroundcolor of the gui. I've tried multiple suggested solutions and they don't work. For example root.configure(background='red'). This doesn't work either: http://www.java2s.com/Code/Python/GUI-Tk/SetFramebackgroundcolor.htm
import tkinter as tk
from tkinter import *
from tkinter import ttk

for F in (StartPage, PageOne):
frame = F(container, self)
self.frames[F] = frame
frame.grid(row=0, column=0, sticky="nsew")
self.show_frame(StartPage)

label.pack(pady=10, padx=10)
button = ttk.Button(self, text="Visit Page One",
command=lambda: controller.show_frame(PageOne))
button2 = ttk.Button(self, text="Ok",
command=lambda: controller.label2)
button.pack()
button2.pack()

root = Dod()

This is very easy...
All you need to do is add a container.config() argument in the init function of the class Dod(tk.Tk) after the argument container.grid_columnconfigure(0, weight=1). Then, add frame.config(bg="black") after self.frames[F]=frame inside the loop for F in (start1,start,P1,P2).[This will give black colour to all frames in the loop]
The code is as follows:
import tkinter as tk
from tkinter import *
from tkinter import ttk
LARGE_FONT = ("Verdana", 12)
def loadmsg(msg):
popupload.fileName = filedialog.askopenfilename(filetypes=(("textfiler", ".txt"), ("Alla filer", ".*")))
class Dod(tk.Tk):
def __init__(self, *args, **kwargs):
tk.Tk.__init__(self, *args, **kwargs)
tk.Tk.wm_title(self, "GUi")
container = tk.Frame(self)
