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?

%history命令非常棒,但不幸的是,它不能让您将%paste 'd保存到sesh中。要做到这一点,我认为你必须在开头执行%logstart(尽管我还没有确认这是有效的)。

我喜欢做的是

%history -o -n -p -f filename.txt

它将在每个输入(o, n和p选项)之前保存输出,行号和'>>>'。请在这里查看文档中的%history。

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。

来自安德鲁·琼斯的网站(存档):

import readline
readline.write_history_file('/home/ahj/history')

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!
