问题描述
我已经创建了一个小的python脚本,可以在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,什么是良好的Python格式样式以下代码:
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 )
Or
shutil.copyfile( remote
if( filecmp.cmp(local, config_file ) )
else local,
config_file )
或
tocopy = remote if( filecmp.cmp( local, config_file ) ) else local
shutil.copyfile( tocopy, config_file )
还是什么?
另外,在python中为多单词名称命名var的首选方法是 to_复制, tocopy, toCopy, ToCopy
Also, what is the preferred way to name var in python for many-word names, is it "to_copy", "tocopy", "toCopy", "ToCopy"
推荐答案
对于条件语句,我可能会选择:
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)
几乎不需要使用内联在这种情况下,如果
There's little need to use the inline y if x else z
in this case, since the surrounding code is simple enough.
