这是mainProgram（）：
def mainProgram():
typedCountry = e.get()
Country = typedCountry.lower()
print 'Your country is: ' + typedCountry + '\n'
if Country in bannedCountries:
banned(typedCountry)
if Country in cpBannedCountries:
cpBanned(typedCountry)
if Country in skrillBannedCountries:
skrillBanned(typedCountry)
if Country in bacsCountries:

我要求用户在一个框中输入一个国家/地区，我有几个不同国家/地区的列表，并检查用户输入是否与每个列表中的任何国家/地区匹配。如果是的话，我运行一个单独的函数来打印一行。
这是主要的tkinter代码
master = Tk()
e = Entry(master)
e.pack()
e.focus_set()
def clear_text():
#WHAT TO ENTER HERE???
b = Button(master, text = "Search", bg="lightyellow", command = mainProgram)
b.pack()
c = Button(master, text="Quit", bg="orange",
command=master.quit)
c.pack()
d = Button(master, text="Clear", bg="orange",
command=clear_text)
d.pack()
mainloop()
在此之前，我有几个不同国家/地区的列表，以及十几个仅为用户打印内容的功能，这与此无关。
我使用tkinter创建一个输入框，用户可以在其中输入国家（输入分配给typedCountry）和三个按钮：搜索，清除和退出。搜索运行mainProgram（）函数，返回的函数将打印到tkinter框。但是，由于我不确切知道它的打印位置，因此我不知道如何告诉“清除”按钮删除文本框中的内容而不会完全破坏它。
当我搜索说美国时，这就是它的样子：
https://i.stack.imgur.com/mPCBm.jpg
然后我搜索奥地利：
https://i.stack.imgur.com/omJPV.jpg
正如您所看到的，一张印在另一张下面，但我需要将它们从包装盒中清除。由于我不知道tkinter在哪里打印这个，所以无论我做什么，我都无法清除它。
如果有帮助，这是主要代码

答案 0 :(得分：0)
您的代码会在每次成功运行查询时创建一个标签，该标签没有分配名称，因此您无法专门解压缩它。标签也是在主窗口的master框内创建的，而不是在框架内部，这是您应该考虑的事项。要从窗口中解压缩所有以前的标签，您应该使用：
slaves = master.pack_slaves()
for s in slaves:
s.pack_forget()
然后重新打包你需要保留的东西。
e.pack()
b.pack()
c.pack()
d.pack()
每个按钮。但是，清除屏幕上的内容后，文本输入框不会为空。因此，如果您愿意，也可以清除它。
foo = StringVar()
e = Entry(master, textvariable=foo)
然后在清除时，添加：
foo.set("")
希望这有帮助！ GL
