I find myself frequently using Python's interpreter to work with databases, files, etc -- basically a lot of manual formatting of semi-structured data. I don't properly save and clean up the useful bits as often as I would like. Is there a way to save my input into the shell (db connections, variable assignments, little for loops and bits of logic) -- some history of the interactive session? If I use something like script I get too much stdout noise. I don't really need to pickle all the objects -- though if there is a solution that does that, it would be OK. Ideally I would just be left with a script that ran as the one I created interactively, and I could just delete the bits I didn't need. Is there a package that does this, or a DIY approach?

还有另一种选择——耻骨瓣切除术。 在“wxpython 2.8文档演示和工具”中,有一个名为“pyslices”的开源程序。

你可以像编辑器一样使用它,它也支持像控制台一样使用----,像交互式解释器一样执行每一行,具有即时回显。

当然,所有的代码块和每个块的结果都会自动记录到一个TXT文件中。

结果被记录在相应代码块的后面。非常方便。

如果使用bpython,所有的命令历史都会默认保存到~/.pythonhist。

要保存命令以供以后重用,您可以将它们复制到python脚本文件中:

$ cp ~/.pythonhist mycommands.py

然后编辑该文件以清理它并将其放在Python路径下(全局或虚拟环境的site-packages,当前目录,在*.pth中提到,或其他方式)。

要将命令包含到你的shell中,只需从保存的文件中导入它们:

>>> from mycommands import *

除了IPython之外,类似的实用程序bpython还有一个“将您输入的代码保存到文件中”的特性

此外,reinteraction为Python会话提供了一个类似笔记本的界面。

来自安德鲁·琼斯的网站(存档):

import readline
readline.write_history_file('/home/ahj/history')

如果你正在使用IPython,你可以使用神奇的%history函数和-f参数p.e将你之前的所有命令保存到一个文件中:

%history -f /tmp/history.py
