Python风格 [英] Python style

问题描述

简单的初学者问题：

我创建了一个小的python脚本，用于在我用于测试的两个文件之间切换。

I've created a small python script to toggle between two files I'm using for testing.

我的问题是，下面的代码是什么是一个好的python格式样式：

My question is, what is a good python format style for the following code:

import filecmp
import shutil

local = "local.txt"
remote = "remote.txt"
config_file = "C:\some\path\file.txt"

shutil.copyfile( remote if( filecmp.cmp(local, config_file ) ) else local, config_file  )

或

shutil.copyfile( remote 
                     if( filecmp.cmp(local, config_file ) ) 
                     else local,
                 config_file  )

p>

Or

tocopy = remote if( filecmp.cmp( local, config_file ) ) else local 
shutil.copyfile( tocopy, config_file )

还是什么？

是对于许多单词名称在python中命名var的优先方式，是to_copy，tocopy，toCopy，ToCopy

Also, what is the preffered way to name var in python for many-word names, is it "to_copy", "tocopy", "toCopy", "ToCopy"

/ p>

Thanks.

推荐答案

对于条件语句，我可能会用：

For the conditional statement, I would probably go with:

if filecmp.cmp(local, config_file):
    shutil.copyfile(remote, config_file)
else:
    shutil.copyfile(local, config_file)

几乎不需要使用inline y if x else z 在这种情况下，因为周围的代码很简单。

There's little need to use the inline y if x else z in this case, since the surrounding code is simple enough.
