如何保存Python交互会话?

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?

对于那些使用spacemacs和python层附带的ipython的人来说，save magic会创建大量不必要的输出，因为不断的自动补全命令在后台工作，例如:

len(all_suffixes)
';'.join(__PYTHON_EL_get_completions('''len'''))
';'.join(__PYTHON_EL_get_completions('''all_substa'''))
len(all_substantives_w_suffixes)
';'.join(__PYTHON_EL_get_completions('''len'''))
';'.join(__PYTHON_EL_get_completions('''all'''))
';'.join(__PYTHON_EL_get_completions('''all_'''))
';'.join(__PYTHON_EL_get_completions('''all_w'''))
';'.join(__PYTHON_EL_get_completions('''all_wo'''))
';'.join(__PYTHON_EL_get_completions('''all_wor'''))
';'.join(__PYTHON_EL_get_completions('''all_word'''))
';'.join(__PYTHON_EL_get_completions('''all_words'''))
len(all_words_w_logograms)
len(all_verbs)

为了避免这种情况，只需保存ipython缓冲区，就像通常保存任何其他:spc f一样

%history命令非常棒，但不幸的是，它不能让您将%paste 'd保存到sesh中。要做到这一点，我认为你必须在开头执行%logstart(尽管我还没有确认这是有效的)。

我喜欢做的是

%history -o -n -p -f filename.txt

它将在每个输入(o, n和p选项)之前保存输出，行号和'>>>'。请在这里查看文档中的%history。

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

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。
