How do I get a output into a tkinter Entry field

Im making my own cypher encryption and I want to put the result into the entry field called output. Now im just using print() so I could test if I got a result. But that was only for testing. This is one of the first times I used Python so if there are some other things I could have done better please let me know :)
this is what I have so far.
from tkinter import *
#Make frame
root = Tk()
root.geometry("500x300")
root.title("Encryption Tool")
top_frame = Frame(root)
bottom_frame = Frame(root)
top_frame.pack()
bottom_frame.pack()
#Text
headline = Label(top_frame, text="Encryption Tool", fg='black')
headline.config(font=('Courier', 27))
headline.grid(padx=10, pady=10)
Key = Label(bottom_frame, text="Key:", fg='black')
Key.config(font=('Courier', 20))
Key.grid(row=1)
Text_entry = Label(bottom_frame, text="Text:", fg='black')
Text_entry.config(font=('Courier', 20))
Text_entry.grid(row=2)
Output_text = Label(bottom_frame, text="Output:", fg='black')
Output_text.config(font=('Courier', 20))
Output_text.grid(row=3)
Key_entry = Entry(bottom_frame)
Key_entry.grid(row=1, column=1)
Text_entry = Entry(bottom_frame)
Text_entry.grid(row=2, column=1)
Output_text = Entry(bottom_frame)
Output_text.grid(row=3, column=1)
#Encryption_button
def encrypt():
result = ''
text = ''
key = Key_entry.get()
text = Text_entry.get()
formule = int(key)
for i in range(0, len(text)):
result = result + chr(ord(text[i]) + formule + i * i)
result = ''
Encryption_button = Button(bottom_frame, text="Encrypt", fg='black')
Encryption_button.config(height = 2, width = 15)
Encryption_button.grid(row = 4, column = 0, sticky = S)
Encryption_button['command'] = encrypt
#Decryption_button
def decrypt():
result = ''
text = ''
key = Key_entry.get()
text = Text_entry.get()
formule = int(key)
for i in range(0, len(text)):
result = result + chr(ord(text[i]) - formule - i * i)
print(result)
result = ''
Decryption_button = Button(bottom_frame, text="Decrypt", fg="black")
Decryption_button.config(height = 2, width = 15)
Decryption_button.grid(row = 5, column = 0, sticky = S)
Decryption_button['command'] = decrypt
#Quit_button
def end():
exit()
Quit_button = Button(bottom_frame, text="Quit", fg='black')
Quit_button.config(height = 2, width = 15)
Quit_button.grid(row = 6, column = 0, sticky = S)
Quit_button['command'] = end
root.mainloop()

The most common way to do this with tkinter would be with a StringVar() object you can connect to the Entry object (Some documentation here).
output_entry_value = StringVar()
Output_text = Entry(bottom_frame, textvariable=output_entry_value)
Output_text.grid(row=3, column=1)
then you can .set() the result in the stringvar, and it will update in the entries you connected it to:
output_entry_value.set(result)

Using get() function on tkinter entry widget

I am trying to create a standard user ID/PASS login. When I use the next function to check if the entered password and name are right, I always get the "wrong values entered" message. Basically, the variables entry_1 and entry_2 are not storing the input text and I want a solution for that. Maybe any of you guys might propose a solution for that?
I have tried to assign entry_1 and entry_2 to variables but it did'nt work out.
from tkinter import *
root = Tk() # creates a window and initializes the interpreter
root.geometry("500x300")
name = Label(root, text = "Name")
password = Label(root, text = "Password")
entry_1 = Entry(root)
entry_2 = Entry(root)
name.grid(row = 0, column = 0, sticky = E) # for name to be at right use sticky = E (E means east)
entry_1.grid(row = 0, column =1)
x = "Taha"
password.grid(row = 1, column = 0)
entry_2.grid(row = 1, column =1)
y = "123"
c = Checkbutton(root, text = "Keep in logged in").grid(columnspan = 2 ) # mergers the two columns
def next():
if a == entry_1 and b == entry_2:
print ("Proceed")
else:
print("wrong values entered")
def getname():
return name
Next = Button(root, text = "Next", command=next).grid(row = 3, column = 1)
root.mainloop() # keep runing the code
I want the program to return "Proceed" once correct values are entered.

in your code you're not checking for the user input anywhere. You should use get() to return user input. I've modified your code accordingly. Now if you enter Taha as username and 123 as password, you'll get the "Proceed" message.
from tkinter import *
root = Tk() # creates a window and initializes the interpreter
root.geometry("500x300")
name = Label(root, text="Name")
password = Label(root, text="Password")
entry_1 = Entry(root)
entry_2 = Entry(root)
name.grid(row=0, column=0, sticky=E) # for name to be at right use sticky = E (E means east)
entry_1.grid(row=0, column=1)
x = "Taha"
password.grid(row=1, column=0)
entry_2.grid(row=1, column=1)
y = "123"
c = Checkbutton(root, text="Keep in logged in").grid(columnspan=2) # mergers the two columns
def next_window():
user_name = entry_1.get()
user_pass = entry_2.get()
if x == user_name and y == user_pass:
print("Proceed")
else:
print("wrong values entered")
def get_name():
return name
Next = Button(root, text="Next", command=next_window).grid(row=3, column=1)
root.mainloop()

thanks to the people who helped, with your help i could find the missing part in the code. i should have used .get() funtion in order to get the entered text back.
here is the upgraded code with some improvements.
from tkinter import *
from tkinter import messagebox
root = Tk() # creates a window and initializes the interpreter
root.geometry("500x300")
name = Label(root, text = "Name")
password = Label(root, text = "Password")
entry_1 = Entry(root)
entry_2 = Entry(root)
name.grid(row = 0, column = 0, sticky = E) # for name to be at right use sticky = E (E means east)
entry_1.grid(row = 0, column =1)
x = "Taha"
password.grid(row = 1, column = 0)
entry_2.grid(row = 1, column =1)
y = "123"
c = Checkbutton(root, text = "Keep in logged in").grid(columnspan = 2 ) # mergers the two columns
def next():
a = entry_1.get()
b = entry_2.get()
if a == "Taha" and b =="123":
messagebox.showinfo("Login", "successfuly logged in ")
root.destroy()
print ("Proceed")
else:
messagebox.showerror("Error", "wrong values entered")
print("wrong values entered")
root.destroy()
Next = Button(root, text = "Next", command=next).grid(row = 3, column = 1)
root.mainloop() # keep runing the code

Creating Tkinter Text boxes and inserting into a dictionary

I have a long chunk of code. I do not want to paste it all here, so let me explain what I am trying to accomplish here. Based on a number provided by the user I want to create that many text boxes and then get what is entered into that text box and insert that into the dictionary. I have tried this a few ways and just cannot get it to work correctly. The list is either empty or it only contains the last text box as the value for each key.

I am trying to create the dictionary using this chunk of code:
i = 0
let = 'A'
while i < number:
letter = Label(top, text = let)
letter.grid(row = 8+(i*4), column = 3)
answer = Text(top, borderwidth = 5, width=50, height=3, wrap=WORD, background = 'grey')
answer.grid(row = 8+(i*4), column = 4)
answerList[let] = answer.get("1.0",END)
i = i+1
let = chr(ord(let) + 1)
I have even tried putting a loop in the preview function but that is when the last box was the only value contained in the dictionary. Any ideas would be appreciated

Please see my commeneted snippet below which demonstrates this:
from tkinter import *
class App:
def __init__(self, root):
self.root = root
self.entry = Entry(self.root) #entry to input number of entries later
self.button = Button(self.root, text="ok", command=self.command) #calls command to draw the entry boxes
self.frame = Frame(self.root)
self.entry.pack()
self.button.pack()
self.frame.pack()
def command(self):
self.frame.destroy() #destroys frame and contents
self.frame = Frame(self.root) #recreates frame
self.text = [] #empty array to store entry boxes
for i in range(int(self.entry.get())):
self.text.append(Entry(self.frame, text="Question "+str(i))) #creates entry boxes
self.text[i].pack()
self.done = Button(self.frame, text="Done", command=self.dict) #button to call dictionary entry and print
self.done.pack()
self.frame.pack()
def dict(self):
self.dict = {}
for i in range(len(self.text)):
self.dict.update({self.text[i].cget("text"): self.text[i].get()})
#the above line adds a new dict entry with the text value of the respective entry as the key and the value of the entry as the value
print(self.dict) #prints the dict
root = Tk()
App(root)
root.mainloop()
The above asks the user how many entry widgets they want to create, fills a frame with those entry widgets and then iterates through the list which contains them on the press of a button, adding a new dictionary entry for each entry widget, where the key of the dict is the attribute text for each entry and the value of the dict is the value of each entry.

python TypeError when using OptionMenu Tkinter [duplicate]

This question already has answers here:
Why is my Button's command executed immediately when I create the Button, and not when I click it? [duplicate]
(5 answers)
Closed 6 years ago.
ive currently been trying to build a GUI application in Tkinter that takes user input from an Entry and subsiquently populate a drop down menu. The probelm is that the OptionMenu keeps throwing:
Traceback (most recent call last):

mealOneButton = Button(root, text = "query database", command = GetEntry(mealOneString))
File "C:/Python34/food2GUIree.py", line 68, in GetEntry
meal = OptionMenu(root, '', *getMeal).pack()
TypeError: __init__() missing 1 required positional argument: 'value'
when i replace getMeal in:

formatted = x.get().split()##gets the entry and forms a list
getMeal = CsvLoadSearch(u, formatted)
meal = OptionMenu(root, '', *getMeal).pack()
with list = [1,2,3,4] or any other list it works fine. why is this?

global variable issues with tkinter python

I am trying to create a simple interface to access the name array with first, last, previous and next functionality. But the global variable I am using as a position tracker is not working. I have already referred to various question. Would really appreciate the help. Here is the code.
from tkinter import Tk, Label, Entry, Button, StringVar, IntVar

Too many typos. Plus, you don't need to declare a global in the outermost program space, just in the function defs. Corrected working code ->
