EDIT: Thanks to #Osadhi Virochana Jayasinghe Si! Using global "vars" inside the buildwindow() function, makes them readable in the called button function. I also had to fix how to get the Values of the Checkbox and text Widget.
Full Fixed code:

I am trying to make a simple GUI do enter Data into a Dictionary. Most things i find online write the Tkinter straight into the .py, but i want to use a Function to Draw the Window, and another Function to do its stuff once a Button is pressed.
Shorted code:
def main_window():
window = tk.Tk()
build_window(window)
window.mainloop()
def build_window(window):
entry_name = tk.Entry(window)
button_go = tk.Button(window, text="Run", command=lambda: write_dict())
button_go.grid(row=7, column=1, sticky="e", padx=2, pady=2)
def write_dict():
i_dict = {}
i_dict["name"] = entry_name.get()
main_window()
And i am getting AttributeError: module 'tkinter' has no attribute 'entry_name'. I tried various ways to get window into write_dict(), but i could never use .get() to read the values inside the Entry Box.
how would i do this?

EDIT:
The Full Errors are these 2, the first one is with the currently posted code, the second is with passing ´window´ into the button.

Add global entry_name,entry_link,entry_xpath,chbox_active,entry_comment under the def build_window(window): It will fix Variable error.
And I fixed all of the issues
Here is the Code:

Now you can get checkbox status and comment box status too.

*First of all, i am trying to create a register system saved into textfile(not real system, i know its not safe to write into textfiles) Created the GUI and then i defined multiple functions which is Menu, register and submit. Submit function is nested and inside register function. The problem is when i nested the functions it doesn't write into textfiles, but when i delete the register function, it works.
When i press register and write something in the Entry box, it didnt record to the text files, i have been scratching my head as to find what the error in my code is.
Edit: I now have put a picture to get better understanding. the blue window is main menu and its the mainloop and the yellow window is appearing when i click register button.*

I do not understand how you write code. You are using too many duplicates. I will not going to explain to you. In line 51 and 54 , I changed command to None. You can replace it.
Here is code:

start.title("Bibliotekapp")
def menu():
start.geometry("500x500")

I'm a beginner, and I've gathered a number of reference sites to make code!
But if you click the button, you'll see the value only for the last item.
Do you happen to know how to get each result in every row! And now you have to enter all the items to get the value, but even if there is a blank, I hope the result will come out for all the input boxes.
I think the code is a little tangled, but it's hard to solve. I'm posting the code's full text.

I want to set my buttons in my Tk window close to each other, but there is too much space between them. They actually have to sit very close to each other, but i can't change their position.
Code:
from tkinter import *
from tkinter import ttk
def Page():
Profile = Tk()
TreeSearchbar = Text(Profile, width=30, height=1, font="Arial 15")
TreeSearchbar.grid(row=0, column=0, sticky=W, pady=5, columnspan=2)
TreeSearchButton = ttk.Button(Profile, text="Search").grid(row=0, column=1, sticky=W, columnspan=2)
Tree = ttk.Treeview(Profile, height=20)
Tree["columns"] = ("value1", "value2", "value3", "value4", "value5", "value6")
Tree.column("#0", width=170)
Tree.column("#1", width=180)
Tree.column("#2", width=0)
Tree.heading("#0", text="1")
Tree.heading("#1", text="2")
Tree.grid(row=1, column=0, sticky="nw", columnspan=2)
Button1 = ttk.Button(Profile, text="Delete").grid(row=2, column=0, sticky=W, pady=12, padx=(20, 0))
Button2 = ttk.Button(Profile, text="Update").grid(row=2, column=1, sticky=W)
Button3 = ttk.Button(Profile, text="Edit").grid(row=2, column=2, sticky=W)
Profile.mainloop()
Page()
Using frames inside your grid cells you will be able to pack controls. That will give you more flexibility in the layout, like this:
from tkinter import *
from tkinter import ttk
def Page():
Profile = Tk()
TreeSearchbar = Text(Profile, width=30, height=1, font="Arial 15")
TreeSearchbar.grid(row=0, column=0, sticky=W, pady=5, columnspan=2)
TreeSearchButton = ttk.Button(Profile, text="Search").grid(row=0, column=1, sticky=W, columnspan=2)
Tree = ttk.Treeview(Profile, height=20)
Tree["columns"] = ("value1", "value2", "value3", "value4", "value5", "value6")
Tree.column("#0", width=170)
Tree.column("#1", width=180)
Tree.column("#2", width=0)
Tree.heading("#0", text="1")
Tree.heading("#1", text="2")
Tree.grid(row=1, column=0, sticky="nw", columnspan=2)
ButtonFrame = ttk.Frame(Profile)
Button1 = ttk.Button(ButtonFrame,
text="Delete").pack(side=LEFT, padx=5, pady=5)
Button2 = ttk.Button(ButtonFrame,
text="Update").pack(side=LEFT, padx=5, pady=5)
Button3 = ttk.Button(ButtonFrame,
text="Edit").pack(side=LEFT, padx=5, pady=5)
ButtonFrame.grid(row=2, column=0)
Profile.mainloop()
Page()
You should grid your areas in the UI and probably apply this principle in each of them, using either grid again, or packer, inside them (although you can use placer it is usually not recommended, to be able to adjust to window size...)
This is the class I'm calling and the function from a different file
class CalcFunc:
def clearScreen(self):
self.log("CLEAR (CE)")
ent.delete(0, END)
This is the Entry Box
ent = Entry(root, textvariable=clc.getBtn, justify=RIGHT, font=10, relief=RIDGE, bd=2, width=15)
ent.grid(row=0, columnspan=3, pady=10)
This is the button I'm clicking to clear the Entry Box
buttonCC = Button(root, text="CLEAR (CE)", height=1, width=20, bg='orange', command=clc.clearScreen)
I'm not sure what the syntax is to be able to to clear an Entry widget from a class basically. That code worked when I had it in the same file but my project requires it to be in a separate file. It's a class project for a calculator and the "clear" button clears the Entry widget. I can post my entire code if that helps. Thank you.
----EDIT----
My Class
import time
class CalcFunc:
def log(self, val):
myFile = open(r".\log.dat", "a")
myFile.write("%s\n" % val)
myFile.close()
def onScreen(self, iVal):
self.log(iVal)
currentTxt = self.getBtn.get()
updateEnt = self.getBtn.set(currentTxt + iVal)
def clearScreen(self):
self.log("CLEAR (CE)")
ent.delete(0, END)
def evaL(self):
self.log("=")
self.getBtn.set(str(eval(self.getBtn.get())))
self.log(self.getBtn.get())
def logLbl(self):
myFile = open(r".\log.dat", "a")
myFile.write("\n==================================\n")
myFile.write("Date: " + str(time.strftime("%m/%d/%Y")) + " -- Time: " + str(time.strftime("%I:%M:%S")))
myFile.write("\n==================================\n")
myFile.close()

class CalcFunc:
def __init__(self, entry):
self.entry = entry
def clearScreen(self):

Here's an abbreviated example:
#my_entry.py
from tkinter import END
import time
class EntryWithLogger:
def __init__(self, entry):
self.entry = entry
def log(self, val):
with open("log.dat", "a") as my_file: #Automatically closes the file--even if an exception occurs, which is not the case with my_file.close().
my_file.write("%s\n" % val)
def onScreen(self, i_val):
self.log(i_val)
self.entry.insert(END, i_val)
def clearScreen(self):
self.log("CLEAR (CE)")
self.entry.delete(0, END)
Note that I didn't use a StringVar(), which doesn't appear to be necessary. If you need it, you can always pass it as an argument to __init__(), then store it on self.
import my_entry as me
import tkinter as tk
root = tk.Tk()
root.title("Calculator")
root.geometry("+100+50") #("300x500+200+10") dimension, position
entry = tk.Entry(root, justify=tk.RIGHT, font=10, relief=tk.RIDGE, bd=2, width=15)
entry.grid(row=0, columnspan=3, pady=10)
entry_with_logger = me.EntryWithLogger(entry)
#Create the buttons in a loop:
for i in range(10):
row_num, col_num = divmod(i, 3) #divmod(7, 2) => (3, 1), divmod(0, 3) => (0, 0), divmod(4, 3) => (1, 1)
row_num += 1
button_text = str(i)
tk.Button(root, text=button_text,
height=1,
width=5,
bg='light blue',
command=lambda x=button_text: entry_with_logger.onScreen(x)
).grid(row=row_num, column=col_num, pady=5)
#Put the clear button at the bottom of the grid:
tk.Button(root, text="CLEAR (CE)",
height=1,
width=20,
bg='orange',
command=entry_with_logger.clearScreen
).grid(row=row_num+1, columnspan=3) #columnspan tells grid() to use 3 cells for the button,
#and the button will be centered by default.
root.mainloop()
Or, you could do it like this:
#my_entry.py
from tkinter import Entry, END
import time
class EntryWithLogger(Entry):
#Because __init__() is not implemented, the parent class's __init__() gets
#called, so you create an EntryWithLogger just like you would an Entry.
