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?

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

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

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
