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

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.

CodePudding user response：

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()
