Stuck trying to save a file from tkinter entry box into .txt file

Not really sure what im doing in this stage tbh, found someone asking a similar thing and tried to include it. However im not sure how to integrate it and at the moment they both do their own tkinter windows. One saving a .txt file, the other producing what ive written.
import sys
import tkinter as tk
from tkinter import *
from tkinter.messagebox import showinfo
root = tk.Tk()
root.wm_title('QR Code Generator')
def login():
frame = Frame(root)
Label(frame, text = "Welcome to QR Code Generator").grid(row = 0)
Label(frame, text = "Enter the link you want as a QR Code ").grid(row = 1)
e1 = Entry(frame)
e1.grid(row=1, column = 1)
Button(frame, text = 'Continue', command = save).grid(row = 4, column = 1, sticky = W, pady = 4)
return frame
def save():
file_name = entry.get()
with open(file_name + '.txt', 'w') as file_object:
file_object.write(file_name)
if __name__ == '__main__':
top = tk.Tk()
entry_field_variable = tk.StringVar()
entry = tk.Entry(top, textvariable=entry_field_variable)
entry.pack()
tk.Button(top, text="save", command=save).pack()
login_frame = login()
login_frame.pack(fill="both", expand=True)
root.mainloop()
wanting the "paste link for qr code" section to be saved into a .txt

Your filename is not defined anywhere in the code
I.e. your filename is empty, this results in a file with no name '.txt'
def save():
file_name = entry.get()
with open(file_name + '.txt', 'w') as file_object:
file_object.write(file_name)
Your code opens two windows, it is being created in this line, whenever you define another instance of Tk() it will be a new window, if you need it, I recommend Toplevel
if __name__ == '__main__':
top = tk.Tk()
Try something cleaner and easier to understand
import tkinter as tk
from tkinter import *
root = tk.Tk()
root.wm_title('QR Code Generator')
def save():
content = e1.get()
with open('your_file.txt', 'w') as file_object:
file_object.write(content)
frame = Frame(root)
frame.pack()
Label(frame, text="Welcome to QR Code Generator").pack()
Label(frame, text="Enter the link you want as a QR Code ").pack()
e1 = Entry(frame)
e1.pack()
Button(frame, text='Continue', command=save).pack()
if __name__ == '__main__':
root.mainloop()

The qrcode is created as a picture. You can write a picture as base64 encoded to a text file, but I recommend to save the picture as an image.
I understood your request as "create" and "show" the saved picture into a tkinter window. I saved the picture with a timestamp.
My prototype:
import tkinter as tk
import qrcode
from PIL import ImageTk, Image
import time
root = tk.Tk()
root.title('QR Code Generator')
root.geometry("450x420")
#root.state("zoomed") whole display size
root.config(bg="#2c3e50")
#root.grid_rowconfigure(0, weight=1)
root.grid_columnconfigure(0, weight=1)
def create_QR(link_input):
print(link_input.get())
lnk = link_input.get()
global qr_img
qr = qrcode.QRCode(version=1, error_correction = qrcode.constants.ERROR_CORRECT_L, box_size=10, border=3)
qr.add_data(lnk)
qr.make(fit=True)
time_str = str(int(time.time()))
img = qr.make_image(fill_color='cyan', back_color='#2c3e50')
img.save(f'qrcode_{time_str}.png')
qr_img = f'qrcode_{time_str}.png'
return qr_img
def show_qr():
global qr_img
qr_img = ImageTk.PhotoImage(Image.open(qr_img))
qr = tk.Label(frame, image = qr_img)
qr.grid(row =3, columnspan = 3, padx = 5, pady = 5)
qr.config(image = qr_img)
return qr_img
l1 = tk.Label(root, text = "Welcome to QR Code Generator", font=("Calibre", 16), bg="#2c3e50", fg="white")
l1.grid(row =0, columnspan = 2, padx = 5, pady = 5)
frame = tk.Frame(root)
frame.grid()
frame.config(bg="#2c3e50")
l2 = tk.Label(frame, text = "Link you want as a QR Code: ", bg="#2c3e50", fg="white")
l2.grid(row =1, column = 1, padx = 5, pady = 5, sticky="w")
link_name = tk.StringVar(frame, value='hhtps://')
e1 = tk.Entry(frame, textvariable = link_name, width=35)
e1.grid(row =1, column = 2, padx = 5, pady = 5)
b_cre = tk.Button(frame, text = 'Create QR Code', command = lambda: create_QR(link_name))
b_cre.grid(row =2, column = 1, padx = 5, pady = 5)
b_sav = tk.Button(frame, text = 'Show QR Code', command = show_qr)
b_sav.grid(row =2, column = 2, padx = 5, pady = 5)
root.mainloop()

How to get the text input from a tkinter text box?

I've made this converter. I want it to convert decimal values into binary and hexadecimal using Tkinter..
I made a text input box but I don't know how to get the input values from the input box.
We aren't supposed to use OOP so we can't use classes.
Here is my code (it's in french for some parts) :
import tkinter as tk
from tkinter import *
def ConverterWind():
convertisseur = Tk()
convertisseur.title("Convertisseur")
inputZone = Text(convertisseur, height=2, width=50)
inputZone.pack()
getTextArea = Button(convertisseur, text = "Convertir !", command = getText)
getTextArea.pack()
convertisseur.mainloop
MainMenu = Tk()
MainMenu.title("Choix de Modes")
button1 = Button(MainMenu, text = "convertisseur", command = ConverterWind)
button1.pack(side = LEFT, padx= 10, pady = 10)
button2 = Button(MainMenu, text = "QUITTER", command = MainMenu.destroy)
button2.pack(side = RIGHT, padx= 10, pady = 10)
MainMenu.mainloop()

You can use the Text.get(Index1,Index2) to get the text from Text widget
Try this.
import tkinter as tk
from tkinter import *
def getText(inputText):
print(inputText.get(1.0,END))
def ConverterWind():
convertisseur = Tk()
convertisseur.title("Convertisseur")
inputZone = Text(convertisseur, height=2, width=50)
inputZone.pack()
getTextArea = Button(convertisseur, text = "Convertir !", command = lambda: getText(inputZone))
getTextArea.pack()
convertisseur.mainloop
MainMenu = Tk()
MainMenu.title("Choix de Modes")
button1 = Button(MainMenu, text = "convertisseur", command = ConverterWind)
button1.pack(side = LEFT, padx= 10, pady = 10)
button2 = Button(MainMenu, text = "QUITTER", command = MainMenu.destroy)
button2.pack(side = RIGHT, padx= 10, pady = 10)
MainMenu.mainloop()

Centering widgets in Tkinter frame using .pack()

I'm trying to get all of my labels and input boxes to be shifted down to the middle of the screen using the .pack() method. I tried using
anchor = CENTER
with the.place() method but that made everything overlap in the center. How can I simply shift all of my widgets to the center of my Tkinter frame?
Here's my code:
from Tkinter import *
root = Tk()
root.minsize(width = 500, height = 500)
root.wm_title("Email Program v1.0")
def callback():
print ("Hello!")
#sign in - email
usernameLabel = Label(root, text = "Email:")
usernameLabel.pack(padx = 0, pady = 0)
usernameInput = Entry(root)
usernameInput.pack()
usernameInput.focus_set()
passwordLabel = Label(root, text = "Password:")
passwordLabel.pack()
passwordInput = Entry(root, show = "*", width = 20)
passwordInput.pack()
passwordInput.focus_set()
#submit email credentials - connect to the server
submitEmail = Button(root, text = "Submit", fg = "black", width = 10, command = callback)
submitEmail.pack()
root.mainloop()

I managed to put those labels and entries to the center using three frames, two without any content just to 'eat' space.
frame1 = Frame(root)
frame1.pack(expand=True)
frame2 = Frame(root)
usernameLabel = Label(frame2, text = "Email:")
usernameLabel.pack(padx = 0, pady = 0)
usernameInput = Entry(frame2)
usernameInput.pack()
usernameInput.focus_set()
passwordLabel = Label(frame2, text = "Password:")
passwordLabel.pack()
passwordInput = Entry(frame2, show = "*", width = 20)
passwordInput.pack()
passwordInput.focus_set()
submitEmail = Button(frame2, text = "Submit", fg = "black", width = 10, command\
= callback)
submitEmail.pack()
frame2.pack(anchor=CENTER)
frame3 = Frame(root)
frame3.pack(expand=True)

The simple solution is to put all the widgets in a frame, and then center the frame.

Run two Commands when you hit a Tkinter Button

I would like a Tkinter button to clear my current Grid, and also go to a function, and I cannot think of how to do it. I have a grid that is a menu, and in another function I have the code for what was just opened by hitting the button.
in short I want a button, when clicked to do this: self.studyGuide and this: self.frame.grid_forget.
Here is my code:
from tkinter import *
class App:
def __init__(self,master):
frame = Frame(master)
frame.grid()
self.sg = Button(frame, text = "Study Guide", command = self.buttonStart, fg="red")
self.sg.grid(row = 2, column = 1)
self.quizlet = Button(frame, text = "Quizlet", command = self.quizlet)
self.quizlet.grid(row = 2, column = 2)
self.flashcard = Button(frame, text = "Flash Cards", command = self.flashcard)
self.flashcard.grid(row = 2, column = 3)
self.quitButton = Button(frame, text = "Quit", command = frame.quit)
self.quitButton.grid(row = 3, column = 2)
self.text = Label(frame, text = "Social Studies Study Tool")
self.text.grid(row = 1, column = 2)
def buttonStart(frame):
self.studyGuide()
self.frame.grid_forget()
def studyGuide(self):
studyGuide = Frame()
studyGuide.pack()
self.sgText = Label(studyGuide, text = "This is not real.")
self.sgText.pack()
def quizlet(self):
print("Quizlet")
def flashcard(self):
print("Flashcards")
root = Tk()
app = App(root)
root.mainloop()

Simply, have the callback passed to the Button constructor call the other 2 functions:
def foo(self):
self.studyGuide()
self.frame.grid_forget()
root = Tk()
my_button = Button(root, text="I'm doing stuff", command=foo)

get previous Entry

I am trying to make a tkinter widget that will remember the previous entry. The problem I am having is the that the button method I made erases the previous entry every time its pressed.
from Tkinter import *
class step1():
def __init__(self):
pass
def getTextbook(self):
temp = str(textbook.get())
textbook.delete(0, END)
x = " "
x += temp
print x
def equal_button(self):
print getTextbook(self)
root = Tk()
root.title("step1")
root.geometry("600x600")
s = step1()
app = Frame(root)
app.grid()
label = Label(app, text = "step1")
label.grid()
textbook = Entry(app, justify=RIGHT)
textbook.grid(row=0, column = 0, columnspan = 3, pady = 5)
textbook2 = Entry(app, justify=RIGHT)
textbook2.grid(row=1, column = 0, columnspan = 3, pady = 5)
button1 = Button(app, text = "Return", command = lambda: s.getTextbook())
button1.grid()
button2 = Button(app, text="Equal")
button2.grid()
root.mainloop()

The variable X in your getTextbook() is being overwritten every time you set it to " ". Try a list instead, and append each entry to the list when the button is pressed:
from Tkinter import *
root = Tk()
textbookList = []
def getTextbook():
textbookList.append(textbook.get())
textbook.delete(0,END)
print textbookList
textbook = Entry(root)
textbook.pack()
btn1 = Button(root, text='Return', command=getTextbook)
btn1.pack()
root.mainloop()
