如何在交互式 Python 中查看整个命令历史记录？

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?

打印整个历史记录的代码：

Python 3

一行（快速复制和粘贴）：

import readline; print('\n'.join([str(readline.get_history_item(i + 1)) for i in range(readline.get_current_history_length())]))

（或者更长的版本...）

import readline
for i in range(readline.get_current_history_length()):
    print (readline.get_history_item(i + 1))

Python 2

一行（快速复制和粘贴）：

import readline; print '\n'.join([str(readline.get_history_item(i + 1)) for i in range(readline.get_current_history_length())])

（或者更长的版本...）

import readline
for i in range(readline.get_current_history_length()):
    print readline.get_history_item(i + 1)

Note: get_history_item()索引从 1 到 n。
