在写入之前tkinter明文框[重复]

Question

这个问题在这里已有答案：

• How to clear/delete the contents of a Tkinter Text widget? 5个答案

我有以下代码，我认为它不会工作，但我只是初学者。有人可以解释一下如何在进入下一个之前让txt清除。如果我打字，我会得到正确的回应，但我希望在得到下一个回复之前清除。

import tkinter

def show_data():
    txtBox = ent.get()

    if txtBox == ("hi" or "hello"):
        txt.delete(0.0, END)
        txt.insert(0.0, sentense)
    elif txtBox == ("i am good"):
        txt.delete(0.0, END)
        txt.insert(0.0, sentense1)
    else:
        txt.delete(0.0, END)
        txt.insert(0.0, sentence3)




window = tkinter.Tk()
window.configure(background="#18e0d9")
window.title("Project One")
window.geometry("300x300")

sentense = ("Hi! How are you?")
sentense1 = ("I'm glad to hear it")
sentence3 = ("i dont understand")


photo = tkinter.PhotoImage(file = 'title.gif')

w = tkinter.Label(window, image=photo)


lblInst = tkinter.Label(window, text="HOW CAN I HELP YOU TODAY?", 
fg="#383a39", bg="#18e0d9", font="bolder")



ent = tkinter.Entry(window, width=38)
btn = tkinter.Button(window, text="submit", fg="#ffffff", bg="#383a39", command=show_data)
txt = tkinter.Text(window, width=29, height=6, bg="#18e0d9")


txt.pack(side="bottom", pady=15)
w.pack()
lblInst.pack(pady=5)
ent.pack(pady=5)
btn.pack(pady=5)



window.mainloop()

Answer 1

正确使用语法，如下所示：

text = tkinter.Text()
text.insert('1.0', 'template') # add template from the start point
text.delete('1.0', 'end') # delete from start to end, entirely
