I'm unable to get a string out of tkinter entrybox

import random
import tkinter as tk
frame = tk.Tk()
frame.title("koeweils baldadige encyptor")
frame.geometry('400x200')
printButton = tk.Button(frame,text = "Print", command = lambda: zandkasteel())
printButton.pack()
freek = tk.Text(frame,height = 5, width = 20)
freek.pack()
input_a = freek.get(1.0, "end-1c")
print(input_a)
fruit = 0
fad = input_a[fruit:fruit+1]
print(fad)
schepje = len(input_a.strip("\n"))
print(schepje)
def zandkasteel():
lbl.config(text = "Ingevulde string: "+input_a)
with open("luchtballon.txt", "w") as chocoladeletter:
for i in range(schepje):
n = random.randint()
print(n)
leuk_woord = ord(fad)*n
print(leuk_woord)
chocoladeletter.write(str(leuk_woord))
chocoladeletter.write(str(n))
chocoladeletter.write('\n')
lbl = tk.Label(frame, text = "")
lbl.pack()
frame.mainloop()
I need to get the string that was entered into the text entry field freek. I have tried to assign that string to input_a, but the string doesn't show up.
Right now, input_a doesn't get anything assigned to it and seems to stay blank. I had the same function working before implementing a GUI, so the problem shouldn't lie with the def zandkasteel.
To be honest I really don't know what to try at this point, if you happen to have any insights, please do share and help out this newbie programmer in need.

Here are some simple modifications to your code that shows how to get the string in the Text widget when it's needed — specifically when the zandkasteel() function gets called in response to the user clicking on the Print button.
import random
import tkinter as tk
frame = tk.Tk()
frame.title("koeweils baldadige encyptor")
frame.geometry('400x200')
printButton = tk.Button(frame, text="Print", command=lambda: zandkasteel())
printButton.pack()
freek = tk.Text(frame, height=5, width=20)
freek.pack()
def zandkasteel():
input_a = freek.get(1.0, "end-1c")
print(f'{input_a=}')
fruit = 0
fad = input_a[fruit:fruit+1]
print(f'{fad=}')
schepje = len(input_a.strip("\n"))
print(f'{schepje=}')
lbl.config(text="Ingevulde string: " + input_a)
with open("luchtballon.txt", "w") as chocoladeletter:
for i in range(schepje):
n = random.randint(1, 3)
print(n)
leuk_woord = ord(fad)*n
print(leuk_woord)
chocoladeletter.write(str(leuk_woord))
chocoladeletter.write(str(n))
chocoladeletter.write('\n')
lbl = tk.Label(frame, text="")
lbl.pack()
frame.mainloop()

How to correctly define variables in Python?

Im writing a program so i can practise my spanish grammer. I come from the world of PLC programming and wanted to delve into Python to get 2 birds stoned at once. Below is the code, it however gives me an error on the syntax as its missing the var RandomVerbNumber in the on_change def. I have tried defining it outside of the def structures, but it will always make RandomVerbNumber have an incorrect value.
I have tried looking into classes and the init function. But that's not very clear to me yet.
import gspread
import random
import tkinter as tk
gc = gspread.service_account(filename = 'credentials.json')
SpanishVerbs = gc.open('Spanish Verbs')
worksheet = SpanishVerbs.worksheet("EnglishSpanishList")
EnglishList = worksheet.col_values(1)
SpanishList = worksheet.col_values(2)
AmountOfRows = len(worksheet.col_values(1))
def on_next(event):
RandomVerbNumber = random.randint(0,AmountOfRows)
EnglishVerbLabel.config(text = EnglishList[RandomVerbNumber])
print(EnglishList[RandomVerbNumber]," = ",SpanishList[RandomVerbNumber])
def on_change(event):
if SpanishEntry.get() == SpanishList[RandomVerbNumber]:
ResultLabel.config(text = "Correct")
else:
ResultLabel.config(text = "Incorrect")
SpanishEntry.delete(0, tk.END)
root = tk.Tk()
QuestionLabel = tk.Label(root, text = "Spanish Verb for:")
EnglishVerbLabel = tk.Label(root)
ResultLabel = tk.Label(root)
SpanishEntry = tk.Entry(root)
root.bind("<Return>", on_change)
buttonNext = tk.Button(root, text="Next", fg="black")
buttonNext.bind("<Button-1>", on_next)
QuestionLabel.grid(row=0, sticky=tk.E)
EnglishVerbLabel.grid(row=0, column=1)
SpanishEntry.grid(row=1, columnspan=2)
buttonNext.grid(row=2, columnspan=2)
ResultLabel.grid(row=3, columnspan=2)
root.mainloop()

RandomVerbNumber is not defined in the function on_change. Why do you think it would be defined?
There does exist a variabel RandomVerbNumber in another function, but that's outside of the scope of on_change. Variables only exists within their scope.

You can pass a randomised array defined in main as an argument into both methods, holding the index values of the words and pop the index value in the on_next method. Your edited code is below, my edits are marked with NOTE tags.
This method works because python lists are passed by reference.
import gspread
import random
import tkinter as tk
gc = gspread.service_account(filename = 'credentials.json')
SpanishVerbs = gc.open('Spanish Verbs')
worksheet = SpanishVerbs.worksheet("EnglishSpanishList")
EnglishList = worksheet.col_values(1)
SpanishList = worksheet.col_values(2)
AmountOfRows = len(worksheet.col_values(1))
#NOTE:
randomisedList = random.sample(range(AmountOfRows), AmountOfRows)
#NOTE: event argument removed
def on_next(list):
EnglishVerbLabel.config(text = EnglishList[RandomVerbNumber])
print(EnglishList[RandomVerbNumber]," = ",SpanishList[RandomVerbNumber])
list.pop()
#NOTE: event argument removed
def on_change(list):
#NOTE:
if SpanishEntry.get() == SpanishList[list[-1]]:
ResultLabel.config(text = "Correct")
else:
ResultLabel.config(text = "Incorrect")
SpanishEntry.delete(0, tk.END)
root = tk.Tk()
QuestionLabel = tk.Label(root, text = "Spanish Verb for:")
EnglishVerbLabel = tk.Label(root)
ResultLabel = tk.Label(root)
SpanishEntry = tk.Entry(root)
#NOTE:
root.bind("<Return>", lambda event, list=randomisedList: on_change(list))
buttonNext = tk.Button(root, text="Next", fg="black")
#NOTE:
buttonNext.bind("<Button-1>", lambda event, list=randomisedList: on_next(list))
QuestionLabel.grid(row=0, sticky=tk.E)
EnglishVerbLabel.grid(row=0, column=1)
SpanishEntry.grid(row=1, columnspan=2)
buttonNext.grid(row=2, columnspan=2)
ResultLabel.grid(row=3, columnspan=2)
root.mainloop()

save entry values for next programmstart tkinter

thanks a lot for your time. I'm currently stuck at the following point: I have developed a GUI with Tkinter with about 200 entries. (For simplification I have only included a small section below). But these 200 entries are seldom filled in at once. Normally 50 entries are filled in every start of the program. When the program is closed, these filled in values are deleted and have to be filled in again after the program is started again. Is there a way to prevent this?
I do not want to lose the values entered in jobNameA_entry and jobNameB_entry when closing the program.
Many thanks in any case.

Pass variables between modules

I have a tkinter gui that has a basic entry box and search button. That searches a list in a module named SearchList.py
Main.py
from tkinter import *
from SearchList import *
root = Tk()
Output = []
def search():
search = e.get()
Output= SearchList.go(search)
#search bar
e= Entry(root, width=50, borderwidth=5)
e.grid(row=0, column=0, columnspan=2)
#search button
doneButton = Button(root, text="Search", width= 10, command=search).grid(row=0, column=4)
#arranges output in a 5 column rectangle
r, c = (1,0)
c_limit= 5
for thing in Output:
myButton = Button(root, text=thing,height=5, width=25, borderwidth=3, padx=10).grid(row=r,column=c)
c+=1
if c == c_limit:
c=0
r+=1
root.mainloop()
This lets me input what I want to search and sends it to the Searchlist.py module and the output (matches from list) is arranged in a rectangle.
SearchList.py
Output = []
def main(search):
for x in range(list):
if list[x]== search:
Output.append(list[x])
else:
continue
Output.sort
return Output
def go(search):
with client:
client.loop.run_until_complete(main(search))
But it keeps returning None.
Also I know I must be calling the module incorrectly- just not sure how.

There are two minor issues here. First you are missing a return in SearchList.py:
def go(search):
with client:
# insert return here
return client.loop.run_until_complete(main(search))
Second, you don't write to the correct variable in search:
def search():
# use global keyword to reference global variable Output
global Output
search = e.get()
Output= SearchList.go(search)

How would I create a reset button for my program relating with the following code?

I am trying to add a reset button but I can't seem to get it to work. I created a main in order to refer back to it when the button is pressed but no luck. Any ideas?
import sys
from tkinter import *
import math
def main():
def closeWin():
myGui.destroy() #Close Window Function
def kiloFunc():
myText = kiloMent.get() #Kilometers to Miles Fuction
convert = 0.62
miles = myText * convert
finalKilo = Label(text = miles,fg='red',justify='center').place(x=200,y=80)
def mileFunc():
myText2 = mileMent.get() #Miles to Kilometers Function
convertTwo = myText2 // 0.62
finalMile = Label(text = convertTwo, fg = 'red',justify='center').place(x=200,y=170)
myGui = Tk()
kiloMent = IntVar()
mileMent = IntVar()
myGui.title("Distance Converter")
myGui.geometry("450x200+500+200")
myLabel = Label(text="Welcome! Please enter your value then choose your option:",fg="blue",justify='center')
myLabel.pack()
kiloEntry = Entry(myGui, textvariable = kiloMent,justify='center').pack()
kilo2milesButton = Button(text = "Kilometers to Miles!", command = kiloFunc).pack()
mileEntry = Entry(myGui, textvariable = mileMent,justify='center').place(x=130,y=105)
miles2kiloButton = Button(text = "Miles to Kilometers!", command = mileFunc).place(x=150,y=135)
reset = Button(text = "Reset Values!", command = main).place(x=10,y=165)
quit = Button(text="Quit", command = closeWin).place(x=385,y=165)
myGui.mainloop()
main()

By calling main() again, you are simply creating another instance of the GUI. What you should do instead is (if I understand correctly), reset the values of the currently existing GUI. You can use the set() method of the GUI objects.
Does
def reset_values():
kiloMent.set(0)
mileMent.set(0)
reset = Button(text="Reset Values!", command=reset_values).place(x=10, y=165)
do the trick?
Looking at your code more thoroughly, however, there are some other problems there, as well. To start with, I would suggest not creating a Label everytime the user tries to convert a value.

This code should work:
from tkinter import *
def main():
def closeWin():
myGui.destroy() # Close Window Function
def kiloFunc():
finalKilo.set(kiloMent.get() * 0.62) # Kilometers to Miles Fuction
def mileFunc():
finalMile.set(mileMent.get() // 0.62) # Miles to Kilometers Function
def clearFunc():
kiloMent.set("0")
mileMent.set("0")
finalKilo.set("")
finalMile.set("")
myGui = Tk()
kiloMent = IntVar()
mileMent = IntVar()
finalKilo = StringVar()
finalMile = StringVar()
myGui.title("Distance Converter")
myGui.geometry("450x200+500+200")
myLabel = Label(text="Welcome! Please enter your value then choose your option:", fg="blue", justify='center')
myLabel.pack()
kiloEntry = Entry(myGui, textvariable=kiloMent, justify='center')
kiloEntry.pack()
kilo2milesButton = Button(text="Kilometers to Miles!", command=kiloFunc)
kilo2milesButton.pack()
mileEntry = Entry(myGui, textvariable=mileMent, justify='center')
mileEntry.place(x=130, y=105)
miles2kiloButton = Button(text="Miles to Kilometers!", command=mileFunc)
miles2kiloButton.place(x=150, y=135)
kiloLabel = Label(textvariable=finalKilo, fg='red', justify='center')
kiloLabel.place(x=200, y=80)
mileLabel = Label(textvariable=finalMile, fg='red', justify='center')
mileLabel.place(x=200, y=170)
reset = Button(text="Reset Values!", command=clearFunc)
reset.place(x=10, y=165)
quit = Button(text="Quit", command=closeWin)
quit.place(x=385, y=165)
myGui.mainloop()
main()
A few notes about your original code besides the ones that Chuck mentioned:
The math and sys imports were unused.
You were setting variables equal to widget.pack() and widget.place(), which are functions that return None.
