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
在安装Ipython并打开Ipython会话后，执行以下命令:
ipython
在你的命令行中，只需运行下面的Ipython 'magic'命令来自动记录你的整个Ipython会话:
%logstart
这将创建一个唯一命名的.py文件，并存储您的会话，以供以后作为交互式Ipython会话使用或在您选择的脚本中使用。

readline.write_history_file('/home/ahj/history')
在IPython中，我首先使用
In [2]: %hist
查看我过去的代码。我选择我想要保存的块，然后使用%%文件魔法(%%writefile的缩写)将其粘贴到文件my_file.py中。
In [3]: %%file my_file.py
...: # paste code here
...:
...:
最后按了两次回车键。
使用选项-a: %%file -a my_file.py追加文件。
如果需要，我可以在底层命令行中使用感叹号列出、编辑文件等
In [5]: !ls -l my_file.py
In [6]: !vi my_file.py
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 *
