在下拉菜单中显示选项不足

Question

当我打印“chunk”时，输出会显示“PY\u VAR0”我哪里出错了

chunk = IntVar(root)
chunk.set("4") # default value to show on the GUI
print chunk

#option for segment size
chunkOption = OptionMenu(root, chunk,"4", "16", "32", "64", "128", "265", "512" )
chunkOption.pack(side=Tkinter.TOP)

Answer 1

要在IntVar中使用值，必须使用get方法获取值：

print chunk.get()
