Implement the function permutations() that takes a list lst as input and returns a list of all permutations of lst (so the returned value is a list of lists). Do this recursively as follows: If the input list lst is of size 1 or 0, just return a list containing list lst. Otherwise, make a recursive call on the sublist l[1:] to obtain the list of all permutations of all elements of lst except the first element l[0]. Then, for each such permutation (i.e., list) perm, generate permutations of lst by inserting lst[0] into all possible positions of perm.

>>> permutations([1, 2])

[[1, 2], [2, 1]]

>>> permutations([1, 2, 3])

[[1, 2, 3], [2, 1, 3], [2, 3, 1], [1, 3, 2], [3, 1, 2], [3, 2, 1]]

>>> permutations([1, 2, 3, 4])

[[1, 2, 3, 4], [2, 1, 3, 4], [2, 3, 1, 4], [2, 3, 4, 1],

[1, 3, 2, 4], [3, 1, 2, 4], [3, 2, 1, 4], [3, 2, 4, 1],

[1, 3, 4, 2], [3, 1, 4, 2], [3, 4, 1, 2], [3, 4, 2, 1],

[1, 2, 4, 3], [2, 1, 4, 3], [2, 4, 1, 3], [2, 4, 3, 1],

[1, 4, 2, 3], [4, 1, 2, 3], [4, 2, 1, 3], [4, 2, 3, 1],

[1, 4, 3, 2], [4, 1, 3, 2], [4, 3, 1, 2], [4, 3, 2, 1]]

Answer:

def permutations(myList: list)-> list:  

   if len(myList) <= 1:  

       return [myList]  

   perm = []  

   for i in range(len(myList)):  

      item = myList[i]  

      seglists = myList[:i] + myList[i+1:]  

      for num in permutations(seglists):  

          perm.append([item] + num)  

   return perm

data = [1,2,3]  

result = permutations(data)  

print(result)

Explanation:

The program defines a python function that returns the list of permutations. The program checks if the length of the input list is less than or equal to one. The function declaration identifies the input and output as lists.

The for loop iterate through the list and the permutations are saved in an empty list in the next loop statement. At the end of the program, the list of lists is returned.

The objective of this task is to use Scapy to estimate the distance, in terms of number of routers, between your VM and a selected destination. This is basically what is implemented by the traceroute tool. In this task, we will write our own tool. The idea is quite straightforward: just send a packet (any type) to the destination, with its Time-To-Live (TTL) field set to 1 first. This packet will be dropped by the first router, which will send us an ICMP error message, telling us that the time-to-live has exceeded. That is how we
This project is based on SEED labs by Wenliang Du, Syracuse University.
get the IP address of the first router. We then increase our TTL field to 2, send out another packet, and get the IP address of the second router. We will repeat this procedure until our packet finally reach the destination. It should be noted that this experiment only gets an estimated result, because in theory, not all these packets take the same route (but in practice, they may within a short period of time). The code in the following shows one round in the procedure
a = IP()
a.dst '1.2.3.4
a.ttl = 3
b = ICMP()
send (a/b)
If you are an experienced Python programmer, you can write your tool to perform the entire procedure automatically. If you are new to Python programming, you can do it by manually changing the TTL field in each round, and record the IP address based on your observation from Wireshark. Either way is acceptable, as long as you get the result
Task: Sniffing and-then Spoofing
In this task, you will combine the sniffing and spoofing techniques to implement the following sniff- and-then-spoof program. You need two VMs on the same LAN. From VM A, you ping an IP X. This will generate an ICMP echo request packet. If X is alive, the ping program will receive an echo reply, and print out the response. Your sniff-and-then-spoof program runs on VM B, which monitors the LAN through packet sniffing. Whenever it sees an ICMP echo request, regardless of what the target IP address is, your program should immediately send out an echo reply using the packet spoofing technique. Therefore, regard-less of whether machine X is alive or not, the ping program will always receive a reply, indicating that X is alive. You need to use Scapy to do this task. In your report, you need to provide evidence to demonstrate that your technique works.

Use the five-step decision-making process discussed in Chapter 1 to analyze the following situations and recommend a course of action.

You are a new salesperson at a large software manufacturing firm. It is three weeks from the end of the sales quarter and you and your sales manager are sitting pretty—you have both already met your sales quota for the quarter. In addition, you just closed another deal with a new customer for $100,000 of software and customer service. This order would put you way over your sales quota for the current quarter. Your manager suggests that you hold this new order so it gets recorded against next quarter. She explains that because sales during the next three months tend to slow down, salespeople frequently miss their quotas and associated sales bonuses for that quarter. Holding this large order to next quarter would help you get an excellent start and almost guarantee that you meet your quota. What would you do?

A data science experiment you are conducting has retrieved two historical observations for the price of Bitcoin(BTC) on December 2, 2017 of 11234 and 12475. Create a Python script that stores these two historicalobservations in a list variable namedbtcdec1.Your data science experiment requires four additional data tasks. The first task is to use the listappend()method to add the BTC price of 14560 to the listbtcdec1. The second task is to create a new empty listnamedbtcdec2and append the BTC prices of 15630, 12475, and 14972. The third task required you to usethe listextend()method to add the contents ofbtcdec2into the listbtcdec1. The fourth and final taskrequires you to use the listsort()method of the listbtcdec1to sort the items in the newly extended list,then use theprintstatement to output the content of listbtcdec1to the Python console.Starter code:_______.
