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。

还有另一种选择——耻骨瓣切除术。 在“wxpython 2.8文档演示和工具”中,有一个名为“pyslices”的开源程序。

你可以像编辑器一样使用它,它也支持像控制台一样使用----,像交互式解释器一样执行每一行,具有即时回显。

当然,所有的代码块和每个块的结果都会自动记录到一个TXT文件中。

结果被记录在相应代码块的后面。非常方便。

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

如果您喜欢使用交互式会话,IPython是非常有用的。例如,在您的用例中,有一个%save magic命令,您只需输入%save my_useful_session 10-20 23,将第10行到第20行和第23行保存到my_useful_session.py(为了帮助实现这一点,每一行都有它的数字前缀)。

此外,文件指出:

此函数对输入范围使用与%history相同的语法,然后将行保存到指定的文件名。

例如,这允许引用旧的会话,例如

%save current_session ~0/
%save previous_session ~1/

查看演示页面上的视频以快速了解功能。

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!
