公园里的草真绿啊,绿得让你感觉那是一块绿地毯;公园里的草真密啊,密得看不见泥土;公园里的草真柔啊,微风一吹,它们就翩翩起舞。
如下所示:
#coding=utf-8 import sys, re, os def getDictList(dict): regx = '''[\w\~`\!\@\#\$\%\^\&\*\(\)\_\-\+\=\[\]\{\}\:\;\,\.\/\&;\&;\&;]+''' with open(dict) as f: data = f.read() return re.findall(regx, data) def rmdp(dictList): return list(set(dictList)) def fileSave(dictRmdp, out): with open(out, 'a') as f: for line in dictRmdp: f.write(line + '\n') def main(): try: dict = sys.argv[1].strip() out = sys.argv[2].strip() except Exception, e: print 'error:', e me = os.path.basename(__file__) print 'usage: %s <input> <output>' %me print 'example: %s dict.txt dict_rmdp.txt' %me exit() dictList = getDictList(dict) dictRmdp = rmdp(dictList) fileSave(dictRmdp, out) if __name__ == '__main__': main()
