Ptags. py of VIM

When reading the help document of ctags, You can see ptags. py, which is used to generate tags for python. The specific directory is in Python source code tools/scripts/ptags. py. You can download it from the python official website.

Source code, decompress and extract ptags. py and put it in the PATH variable search directory. Both python2.x and python3.x have corresponding ptags. PY, in fact, the principle is the same here, it does not involve 2. X and 3. there are different syntaxes between X, and the generated tags file is mainly for classes and functions (class and DEF). Therefore, there is no difference. You can completely claim the tags of python3.x, use pytags of python2.x.
