Python

Below applies to Python 2.6 or lower, Python 3 is a good bit different.

Python is an object oriented, interpreted language. It is unique in that it requires a user to indent in place of using curly brackets ({..}).

Note: that most *nix distributions come with Python by default.

Basic python syntax

>>> print "HELLO WORLD!"
HELLO WORLD!

Variable names DO NOT need to begin with a special character, unlike PHP. Variable names CAN, however, be any combination, as long as the word isn't reserved (Ex: and, or, print), of letters and numbers.

>>> #Numbers
>>> a = 1 #Declare A as 1
>>> b = a+5 #b becomes 6, while a remains 1
>>> a += 5 #a is overwritten, and becomes 6
>>> c = b = a #c and b are overwritten and become 6
>>> #Strings
>>> a = "Hello "
>>> b = "There"
>>> c = a+b #JOIN STRINGS
>>> a = "Blue Yellow Green Red".split(" ") #Split the string at every " "
>>> a #Output 'a' to the screen, same as print or print()
['Blue', 'Yellow', 'Green', 'Red'] #List object, another type of variable
>>> .join(a) #Join all the list objects as one
'BlueYellowGreenRed'
>>> a = 'Blue Green Yellow Red'[0:4] #This returns the sub-string 'Blue'
>>> a = 'Blue Green Yellow Red'[5:] #This returns the sub-string 'Green Yellow Red'
>>> a = 'a = 'Blue Green Yellow Red'[::2] #This returns the sub-string Bu re elwRd'
>>> #Float 
>>> a = 88.2
>>> b = 88
>>> print a/25
3.528
>>> print b/25
3
>>> #Other types
>>> a = (" ", 355, 256.7, ["Hello", "World"])
>>> type(a)
<type 'tuple'>
>>> a = {"Hello":"World", "Key":"Value"}
>>> type(a)
<type 'dict'>
>>> a = "Anhero"
>>> del a #Its a good idea, if you're making a 'hidden' script, to delete variables after you use them...

No!

Yes!

print a

Consider using xrange when dealing with larger lists, as it creates an iterator, rather than constructing the full list in memory.

>>> for x in ['Hello', 'world', ',this', 'is', 'a', 'list']:
print x

 	
Hello
world
,this
is
a
list

Scapy is a powerful, low-level, networking tool

fast, simple packet creation / parsing, with definitions for the basic TCP/IP protocols.

Twisted is an event-driven networking engine written in Python and licensed under the MIT license.

Tornado is an open source version of the scalable, non-blocking web server and tools that power FriendFeed. The FriendFeed application is written using a web framework that looks a bit like web.py or Google's webapp, but with additional tools and optimizations to take advantage of the underlying non-blocking infrastructure.
