Python：为什么IDLE比终端慢？ [英] python: why IDLE is slower than terminal?

问题描述

我刚刚编写了一个简单的python命令，以检查csv文件中的大列表。 csv有2列，每行10K。当我将第二行输入到列表中并随后打印该列表时，IDLE需要相当长的时间才能显示它在终端（在Mac下）迅速显示它的位置。 *顺便说一句，我在2台不同的机器上进行了检查-结果相同。

I just wrote a simple python command to check on a big list from a csv file. The csv has 2 columns with 10K lines. when I input the 2nd row into a list and later print the list, it takes the IDLE quite some time to show it where the terminal (under mac) shows it promptly. *BTW, I checked it on 2 different machines - same result.

很明显，没有人会在控制台上打印1万个项目，但是这个想法要比打印速度快得多另一个让我感到疑惑的是：为什么IDLE（应该是python最好的朋友）这么慢？

Obviously, no one will print 10k items on a console but the idea that one is significantly faster than the other makes me wonder: why IDLE which supposed to be python's best friend is so slow?

推荐答案

IDLE如何处理将文本打印到输出窗口；尝试注释掉 print 语句，看看性能差距是否仍然存在。请参阅与此密切相关的线程： Python：为什么IDLE这么慢？

The bulk of the problem is in how IDLE handles printing of text to the output window; try commenting out the print statement and see if the performance gap remains. See this closely related thread: Python: Why is IDLE so slow?
