你如何看到交互式python中的整个命令历史？(how do you see the entire command history in interactive python?)

你如何看到交互式python中的整个命令历史？(how do you see the entire command history in interactive python?)

我正在Mac OS X上使用默认的python解释器，而我的Cmd + K（已清除）我以前的命令。 我可以使用箭头键逐个通过它们。 但是有没有像bash shell中的--history选项这样的选项，它显示了你迄今为止输入的所有命令？

I'm working on the default python interpreter on Mac OS X, and I Cmd+K (cleared) my earlier commands. I can go through them one by one using the arrow keys. But is there an option like the --history option in bash shell, which shows you all the commands you've entered so far?

使用readline.get_current_history_length()获取长度，并使用readline.get_history_item()来查看每个。

Use readline.get_current_history_length() to get the length, and readline.get_history_item() to view each.
