    文件 1 内容如下 

    #some words
    Sometimes in life,
    You find a special friend;
    Someone who changes your life just by being part of it.
    Someone who makes you laugh until you can't stop;
    Someone who makes you believe that there really is good in the world.
    Someone who convinces you that there really is an unlocked door just waiting
    for you to open it.

    This is Forever Friendship.

     

    使用读文件过滤空行和注释行

    import re
    file=open("1",'r')
    a=file.readlines()
    a.sort()
    for  line in  a:
            if  re.match("^#",line):
                    pass
            elif  re.match("^$",line):
                    pass
            else:
                    print line.strip()
