vim 之ptags.py

在看ctags的協助文檔時看到了ptags.py，專為python產生tags.具體目錄位於python原始碼的Tools/scripts/ptags.py。自己可以到Python官網下載

原始碼，解壓提取ptags.py放在path變數搜尋的目錄裡。Python2.x和Python3.x都有對應的ptags.py ，其實這裡面的原理是一樣的，根本不涉及到2.x和3.x之間有差異的文法，而且產生的tags檔案也主要是針對類和函數（class and def)所以，沒有什麼區別，完全可以在想聲稱python3.x的tags時，使用python2.x的pytags。

[wolf@localhost tmp]$ diff ptags.py ptags3.py<br />1c1<br />< #! /usr/bin/env python<br />---<br />> #! /usr/bin/env python3<br />##就只有那麼點差異而已，解譯器使用的不一樣而已。
