我正在使用tkinter创建GUI。
在下面的代码中，我使用两种方法在GUI的屏幕上放置标签。
在方法1中，我初始化了label，然后使用label_place和label_forge t将标签放在不同的屏幕上。
在第二种方法中，我使用指向label文本变量选项的指针，并使用set()属性将文本设置在不同的位置。
我想知道哪种方法有效。
与每个页面上的方法1一样，我必须使用forget方法，然后替换标签。
在第二种方法中，我pointer[i].set("text")进行测试，pointer[i].set(" ")没有文字。

如何检查执行速度以及此python代码占用的内存或执行的代码执行时间。
答案 0 :(得分：0)
我使用操作系统的时间命令。请注意，它为您提供了三个系统时间，用户时间和挂钟时间。
/ usr / bin / time -v program_name.py
您还可以使用top或htop查看内存使用情况，但程序运行时使用情况将始终发生变化。还有ps和smaps但我也没用过。
results are something like the following (note that modern systems
use as much of the CPU as is available and give up some of it when
necessary. I am on a multi-core system so the program had
all of one core to itself).
