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?

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。

我不得不努力寻找答案，我对iPython环境非常陌生。

这是可行的

如果你的iPython会话是这样的

In [1] : import numpy as np
....
In [135]: counter=collections.Counter(mapusercluster[3])
In [136]: counter
Out[136]: Counter({2: 700, 0: 351, 1: 233})

你想保存从1到135的行，然后在同一个ipython会话上使用这个命令

In [137]: %save test.py 1-135

这将把你所有的python语句保存在当前目录下的test.py文件中(你启动ipython的地方)。

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

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:
