我是一個新手程序員,我正在製作一個貨幣轉換器....它仍在進行中,但任何人都可以幫助我嘗試替換'def convert()'中製作的標籤...要清楚,現在每次我轉換,一個新的標籤底下彈出,但我希望發生的是,我的標籤被替換每次我點擊轉換...如何替換Tkinter python中的標籤?
import sys
from Tkinter import *
root = Tk()
root.title("CURRENCY CONVERTER")
root.geometry('600x300+30+100')
root.config(bg="#000000")
#*************************************GBP*************************************#
def rate():
rate = 1
if var.get() =='GBP' and var2.get() =='USD':
rate=float(1.63452)

rate=float(1.19529)

這麼糊塗請幫我。我不知道,這裏超級菜鳥!
def convert():
newValue=(var.get(), int(entarr.get()),">>>", round((float(entarr.get())*rate()),3), var2.get())
converted=Label(root, textvariable=newValue)
converted.config(font=('century gothic',(15)),bg='#000000',fg="white",width=0, relief=FLAT)
converted.config(text=newValue)
converted.pack(expand = 1,anchor="center")
return
嗨,非常感謝你回答......但正如我所說,我是一個超級新手,你能編輯我的代碼,告訴我你的意思嗎?再次感謝 –
