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?

此外,reinteraction为Python会话提供了一个类似笔记本的界面。

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。

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。

你可以用内置函数打开:我用它在我的所有 我需要存储一些历史的程序(包括计算器等) 例如:

#gk-test.py or anything else would do
try: # use the try loop only if you haven't created the history file outside program
    username = open("history.txt").readline().strip("\n")
    user_age = open("history.txt").readlines()[1].strip("\n")
except FileNotFoundError:
    username = input("Enter Username: ")
    user_age = input("Enter User's Age: ")
    open("history.txt", "w").write(f"{username}\n{user_age}")
#Rest of the code is secret! try it your own!

我要感谢所有喜欢我评论的人!感谢您的阅读!

保存XUbuntu的输入输出:

在XWindows中,从Xfce终端应用程序运行iPython 单击顶部菜单栏中的“终端”,在下拉菜单中查找保存内容

我发现这节省了输入和输出,一直追溯到我打开终端的时候。这不是特定于ipython的,它与ssh会话或从终端窗口运行的其他任务一起工作。

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
