root.mainloop()这可能包括设置帧大小和帧，以及禁止分发，我的一个朋友说。希望这对你有帮助写回答邀请回答小时前如何使文本小部件静态？写回答如果你给文本小部件一个固定的高度和宽度，并将其包装在一个具有相同宽度和高度的框架中，则使用grid_propagate(False)，当文本变得更大时，文本小部件保持相同的大小。import tkinter as tk
def fontUp():
text.config(font = (&30&))
root = tk.Tk()
root.geometry(&800x800&)

frm.grid_propagate(False)
text = tk.Text(frm, height = 500, width = 500)
text.grid(row = 0, column = 0)
btn = tk.Button(root, text=&Font bigger&, command = fontUp)
btn.grid(row = 2, column = 0)回答过的其他问题这可能是一个并发问题，因为打印出图像内容的行将在回调完成之前执行，这是背景任务的性质。如果你确实想看到图像的打印内容，则可以在回调中打印它，或者完全在for循环外部打印。它可能会发生，因为你选择的设备可能无法支持选定的目标。因此，根据设备规范更改目标。因为一些低分辨率设备不支持更高的API级别的目标。 它是在执行文件I/O时释放的，这意味着可以并行读取文件。因为从进程的角度来看，没有文件这样的东西，只有文件描述符(假设POSIX)，那么无论你读取什么，它都不必存储在磁盘上。 总之，如果将文件移动到(例如)tmpfs或者是ramdisk或任何类似的工具，那么应该可以获得更好的性...... import configparser
