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

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

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。

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。

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
