-B Don't write .py[co] files on import. 不产生pyc或者pyo文件
-c 执行字符串参数 如 python -c "print 1"
-d 产生调试信息
-E Ignore environment variables like PYTHONPATH and PYTHONHOME that modify the behavior of the interpreter. 忽略环境变量
-i 执行完脚本以后 会打开解释器 在调试时候使用比较好
-m 比如 python -m SimpleHTTPServer 8088 从sys.path找到一个模块然后执行模块代码
-O 基本优化 会丢掉docstring
-R hash() 返回伪随机数
-Q 控制两个整数相除得到的类型 如 python -Q new -c "print 10/100"
-v 显示加载模块 如 python -v -c "print 1"
-s Don't add user site directory to sys.path.
-S Disable the import of the module site and the site-dependent manipulations of sys.path that it entails.
-t 检测tab和空格混用 给出警告
-u Force stdin, stdout and stderr to be totally unbuffered. On systems where it matters, also put stdin, stdout and stderr in binary mode. Note that there is internal buffering in xreadlines(), readlines() and file-object iterators ("for line in sys.stdin") which is not influenced by this option. To work around this, you will want
to use "sys.stdin.readline()" inside a "while 1:" loop.
from subprocess import Popen, PIPE

def get_traceroute_res(hostname, max_hop=10):
p = Popen(['traceroute', '-m', str(max_hop), hostname], stdin=PIPE, stdout=PIPE, stderr=PIPE)
output, err = p.communicate()
rc = p.returncode
return output
def get_all_ip(result):
reip = re.compile(r'(?<![\.\d])(?:\d{1,3}\.){3}\d{1,3}(?![\.\d])')

try:
print ip_info['country_name'], ip_info['latitude'], ip_info['longitude'], ip
except Exception, error:

不记得第一次在哪里看到这句话(You had me at hello.)，一开始不知道什么意思，后来百度，类似中文“一见钟情”的意思。不过，还是觉得原文更有画面感：两个陌生人，也许在他人相互介绍后，笑着说句"hello"(不过惯例应该是Nice to meet you啊，哈哈)，然后内心各种澎湃。而一见钟情貌似有很多种方式，我能想到的多半是男生面对漂亮女生，瞬间感觉fucking high，就像You are beautiful中所描述的一样。
我曾有过一见钟情，不过还好，没有在fucking high后，因再也见不到而投海自尽。为什么是一见钟情而不是You had me at hello，因为我的hello还未说出口就没有然后了。可见，'You had me at hello.'和"一见钟情"还是有区别的，可以想象的画面是这样的：两人互有好感以后，有天谈论起什么时候有的感觉，在耳边小声地说：You had me at hello.而一见钟情根据我的经历可能就没有那种耳鬓厮磨的甜腻了。极端者如James Blunt所演绎的那样。
