Also, as another example of Python's flexibility, it can be used as the embedded scripting language for VIM. While writing this article, I grew tired of manually replacing > with >, so I composed the following function and put it in ~/vim-htmlify.py:

 
# a little macro for VIM that helps when composing HTML documents
import vim, string, htmlentitydefs
htmlequivs = {}
# swap built-in table, we want a dictionary indexed by
# characters that can't be used.
for key, value in htmlentitydefs.entitydefs.items():
        if key != "amp":
                htmlequivs[value] = key
def htmlify():
        for i in range(0, len(vim.current.range)):
                cLine = vim.current.range[i]
                                cLine = string.replace(cLine, "&", "&")
                for badchar in htmlequivs.keys():
                        cLine = string.replace(cLine, badchar, "&" + h
tmlequivs[badchar] + ";")
                vim.current.range[i] = cLine
        print len(vim.current.range), "line(s) HTMLified"



and put this in ~/.vimrc:


pyfile ~/vim-htmlify.py
map h :py htmlify()<CR>

With the touch of "h", I could convert <b>Foo Bar</b> into &amplt;b&ampgt;Foo Bar&amplt;b&ampg. This is yet another example of the power and ubiquity of Python!
