The Zen of Python, by Tim Peters

Beautiful is better than ugly.
Explicit is better than implicit.
Simple is better than complex.
Complex is better than complicated.
Flat is better than nested.
Sparse is better than dense.
Readability counts.
Special cases aren't special enough to break the rules.
Although practicality beats purity.
Errors should never pass silently.
Unless explicitly silenced.
In the face of ambiguity, refuse the temptation to guess.
There should be one-- and preferably only one --obvious way to do it.
Although that way may not be obvious at first unless you're Dutch.
Now is better than never.
Although never is often better than *right* now.
If the implementation is hard to explain, it's a bad idea.
If the implementation is easy to explain, it may be a good idea.
Namespaces are one honking great idea -- let's do more of those!

amazon上的书评讲的很好,这本书缺少
"1. Using scapy or impacket for network tricks
2. Using python for phishing (this is a potential hot topic -- the Metasploit guys are working on a phishing addition for the framework so seeing something similar in python would be a plus).
3. Using python for generic security applications: web scraping, social network enumeration, gluing security tools, etc "
