将txt文件分块的模块util.py:

def lines(file):
    for line in file:yield line
    yield '\n'

def blocks(file):
    block = []
    for line in lines(file):
        if line.strip():
           block.append(line)
        elif block:
           yield ''.join(block).strip()
           block=[]

简单的转换模块simple_markup.py:

import sys,re
from util import *

print '<html><body>'

title = True
for block in blocks(sys.stdin):
    block = re.sub(r'\*(.+?)\*',r'<em>\1</em>',block)
    if title:
        print'<h1>'
