好的,所以我遇到了問題。我正在嘗試製作一個GUI十六進制轉換器,並且保持相同的錯誤。我不是那種經驗豐富的人,所以有人能幫助我嗎?這裏是代碼:在標籤上使用.config()時出現python錯誤
from Tkinter import *
def getNum():
hex1 = e1.get()
dec1 = int(hex1, 16)
ol.configure(text=dec1)
root = Tk()
introLabel = Label(root, text='Input Hex Code: ').pack()
e1 = Entry(root)
e1.pack()
e1.focus_set()
inputButton = Button(root, text='Submit Hex Code', command=getNum).pack()
ol = Label(root, text='Hex Code will appear here.').pack()
root.mainloop()
,我不斷收到此錯誤:
Exception in Tkinter callback
Traceback (most recent call last):
File "C:\Python27\lib\lib-tk\Tkinter.py", line 1470, in __call__
return self.func(*args)

ol.configure(text=dec1)
