我需要獲取輸入到文本輸入欄位中的字串freek。我試圖將該字串分配給input_a，但該字串未顯示。
現在，input_a沒有任何分配給它，似乎保持空白。在實作 GUI 之前，我有相同的功能，所以問題不應該出在def zandkasteel.
老實說，我現在真的不知道該嘗試什么，如果您碰巧有任何見解，請分享并幫助這位有需要的新手程式員。
uj5u.com熱心網友回復：
下面是對代碼的一些簡單修改，展示了如何在Text需要時獲取小部件中的字串——特別是當zandkasteel()函式被呼叫以回應用戶單擊Print按鈕時。
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()
