将Markdown转换为微信排版

在简书上用Markdown写东西，会慢慢形成一定的写作格式，比如我。另外，我还会把一些简书上写的东西更新到个人公众号上。久而久之公众号排版也形成了一定的格式。这两种格式可以对应上，所以每次排版的操作几乎是重复的。所以我自学了一点Python，方便我把Markdown很快的转换为微信文章的排版。

代码如下，希望也能帮你加快排版速度。另外，我只是个菜鸟，还求大神指点。

#open a file
fname = raw_input('Which article:')
print fname
try:
    fhand = open(fname)
except:
print "Can't find:",fname
fname = raw_input("Input the right name:")
#already opened, I got a handle

#tell where to write or build a new file
#actually, I can build a new one in the same document folder
dotposition = fname.find('.')
outname = fname[:dotposition] + 'out.txt'
print outname
fout = open(outname,'w')
linkname = fname[:dotposition] + 'link.txt'
fout_link = open(linkname,'w')

#define how to exchange markdown label, I shall save them in a txt docment someday
