使用tkinter模块重叠状态

Question

我正在尝试使用tkinter模块在GUI上工作。 我使用随机问候语生成器创建了标签。 但是，它们与先前生成的标签重叠。这是代码：

import tkinter
import random

window = tkinter.Tk()
# to rename the title of the window
window.title("GUI")

window.geometry("500x500")

#defining Functions
def search_greetings():
    phrases = ["Hallo ", "Hoi ", "Greetings "]
    name = str(entry1.get())
    text = ".Please enter your search term below."
    return phrases[random.randint(0, 2)] + name + text

def search_display():
    greeting = search_greetings()
    # This creates the text field
    greeting_display = tkinter.Label(window,text = search_greetings())
    greeting_display.grid(row=6,column=1)
    search_box = tkinter.Entry()
    search_box.grid(row=7)


# pack is used to show the object in the window
label = tkinter.Label(window, text = "Hello World! Welcome to my app")
label.grid(row = 0)

# creating 2 text labels and input labels

tkinter.Label(window, text = "Username").grid(row = 2) # this is placed in 1 0
# 'Entry' is used to display the input-field
entry1 = tkinter.Entry()
entry1.grid(row = 2, column = 1) # this is placed in 1 1

tkinter.Label(window, text = "Password").grid(row = 3) # this is placed in 2 0
tkinter.Entry().grid(row = 3, column = 1) # this is placed in 2 1

# 'Checkbutton' is used to create the check buttons
tkinter.Checkbutton(window, text = "Keep Me Logged In").grid(columnspan = 2) # 'columnspan' tells to take the width of 2 columns
                                                                             # you can also use 'rowspan' in the similar manner


# Submit button
button = tkinter.Button(text = "Submit",command = search_display).grid(row = 5)     

window.mainloop()

它会返回如下标签：Greetings1234。请在下面输入搜索词。

G Hallo ashita。请在下面输入搜索词。

G Hallo ashita。请在下面输入搜索词。

请检查代码中的错误。

好像您每次都在制作一个新标签。 您可以这样编辑标签的文本：

mylabel = tkinter.Label(root, text="First!")
mylabel["text"] = "Second!"

这将显示“第二！” （打包后）。 打包标签后，您甚至可以更改文本。
