完成计算后，如何使用Shutil自己制作python文件副本? [英] How do I use shutil to make a python file copy itself after doing a calculation?

问题描述

因此，我有一个将质数写入csv文件的python程序.现在，我希望我的python文件在运行所有命令后对其自身进行复制，以作为我调整原始文件时的备份.

So I have a python program that writes prime numbers into a csv file. I now want my python file to make a copy of itself after it runs everything, as a backup for when I tweak around with the original file.

通过使python程序创建一个新的.py文件然后在其中写入所有内容，到目前为止我还不了解这一点，但这效率极低.我希望它更干净，更简单.

I've gotten away with not knowing this so far by making the python program make a new .py file and then writing everything inside it, but this is super inefficient. I'd like it to be cleaner and less complicated.

我听说过一些关于使用shutdownil.copyfile的信息，但是我不太确定如何使用它.shutil.copyfile是使自己的python文件复制自身的最佳方法，还是有更好的方法?

I've heard a little bit about using shutil.copyfile, but I'm not too sure about how to use it. Is shutil.copyfile the best way to make my python file copy itself, or is there a better way?

推荐答案

版本控制软件旨在解决此问题，即保留旧文件的副本.按照自己的方式进行操作将使您的源文件夹非常混乱.Mercurial/Hg 非常容易学习和使用(它也是用python编写的).

Revision control software is meant to solve this problem, that is, keeping a copy of your old files. Doing it your way will make your source folder really cluttered. Mercurial/Hg is really easy to learn and use (its also written in python).

否则，回答问题:

shutil.copy(__file__, "new_destination.py")
