这样写应该够有 python 风格了,各位看看。

[dbow]

def t_join(path, *args):
----return "%s/%s" % (path.rstrip("/"), "/".join([p.strip("/") for p in args if p]))

t_join("/usr", "local", "share/resource")

=>/usr/local/share/resource

[liluo]

import os
os.path.join("/usr", "local", "share/resource")

[dbow]

@liluo 就是重写的os.path.join

[jarlyyn]

感觉这是js风格，不是python风格

[keakon]

@dbow 逻辑错了

原版，自己脑补空格吧：
def join(a, *p):
"""Join two or more pathname components, inserting '/' as needed.
If any component is an absolute path, all previous path components
will be discarded. An empty last part will result in a path that
ends with a separator."""
path = a
for b in p:
if b.startswith('/'):
path = b
elif path == '' or path.endswith('/'):
path += b
else:
path += '/' + b
return path

[mengzhuo]

t_join("/usr", "local", "share/resource")

*args 属于implicit，不符合Pythonic的Explicit
罚LZ
import this

@mengzhuo

*args **kwargs 用处很大， 给代码带来很多自由和方便
而且 LS 也贴出了原版代码， 都用了 *args

[jprovim]

@keakon 我感覺原版的更容易理解.
