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?

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

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

来自安德鲁·琼斯的网站(存档):

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

一些评论询问如何一次保存所有的IPython输入。对于IPython中的%save魔术,您可以以编程方式保存所有命令,如下所示,以避免提示消息,也避免指定输入数字。 currentLine = len(In)-1 %save -f my_session 1-$currentLine

f选项用于强制替换文件,len(IN)-1显示IPython中的当前输入提示符,允许您以编程方式保存整个会话。

如果您喜欢使用交互式会话,IPython是非常有用的。例如,在您的用例中,有一个%save magic命令,您只需输入%save my_useful_session 10-20 23,将第10行到第20行和第23行保存到my_useful_session.py(为了帮助实现这一点,每一行都有它的数字前缀)。

此外,文件指出:

此函数对输入范围使用与%history相同的语法,然后将行保存到指定的文件名。

例如,这允许引用旧的会话,例如

%save current_session ~0/
%save previous_session ~1/

我再提一个建议: 世爵

它有历史日志和变量资源管理器。如果你用过MatLab,你就会发现其中的相似之处。
