Python: Retrieve list of sockets on current machine?
I'm brand new to Python (as of last week) and I'm still getting to grips with the basics so please excuse any ignorance I display.
As part of my homework I have been asked to make a basic port scanner and one of the functions I have to include is the retrieval of a list of sockets on the current machine. I have been looking around and managed to piece together a piece of code that allows me to enter the IP of the machine I wish to scan but I want to try and make it so it automatically scans whichever machine it is running on.
elif (userChoice == "4"):
print("You selected " + userChoice)
try:
s = socket.socket(socket.AF_INET,socket.SOCK_STREAM) # s will be equal to the command looking for the IPV4 addresses
except socket.error:
sys.exit("Failed to create socket.") # error handling message to be printed to the console should a socket failed to be created
print("Socket created")
hostAddress = input("Please enter host address to scan - example 'www.server.com': ")
print ("You entered " + hostAddress )
try:
remoteIP = socket.gethostbyname(hostAddress)
except socket.gaierror:
sys.exit("Hostname could not be resolved exiting")
ret = input("Hit return to go back to the menu")
continue
print("IP address of " + hostAddress + ' is ' + remoteIP)
This is my code so far. If anyone could help me out or tell me if I'm even going in the right direction with this I would be very grateful.
Also, with me being a noob, if anyone has any suggestions for good reading materials to help me get to get to grips with the basics I would very much appreciate it.
Thanks.

Answer 1
To check open ports on remote server-
# For input hostAddress
remoteIP = socket.gethostbyname(hostAddress)
for port in range(1,1025):
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
result = sock.connect_ex((remoteIP, port))
if result == 0:
print("Port %s: Open"%port)
sock.close()
=> Port 80: Open

Python: Retrieve items from a set
In general, Python sets don't seem to be designed for retrieving items by key. That's obviously what dictionaries are for. But is there anyway that, given a key, you can retrieve an instance from a set which is equal to the key?
Again, I know this is exactly what dictionaries are for, but as far as I can see, there are legitimate reasons to want to do this with a set. Suppose you have a class defined something l...
tuple in redis / python: can store, not retrieve
So, I've got redis working with python -- exciting!
I need to store a tuple and retrieve it / parse it later. Construct below isn't working, I think because the returned tuple is quoted -- there is a quote on either end of it.
It seems to me that the quotes indicate that it isn't actually a tuple, but rather a string.
So does anyone know how to get redis to actually return a working tuple? Thank...

Python: Retrieve Tuples From Set Based on First Value of Tuple
Suppose I have a set, s that looks like this:
s = set([(1,2), (1,4), (2,6)])
I want to retrieve all tuples in my set that have first element 1. Usually I'd have to give a full tuple, something like:
(1,2) in s
In this case, I want to retrieve all tuples of the form (1,_) where _ can be any number.
