Question 17 5 pts Problem 5 Write a program. You have been hired as a programmer and a Unix administrator asked you to check these three lists of users to find who had logged into all Unix servers and who had logged only into the main Unix server. Here are the lists: Main Unix Server: Server II: Server III: alex maya akhmed linda mila kyrill kyrill andrew linda akhmed rosa maya sandra linda alex You need to write a program that takes all these user data and generates the right answers for the questions asked by the Unix administrator. (Hint: Use sets and set operations.) Assume that the input are names entered by the program user one at a time on the keyboard, and the output are names of the users who had logged into all Unix servers and the users who had logged only into the main Unix server (you must use set's operations!). Write your program below: mainserver = 0 server 1 = 0) server2 - 0 your code goes here HTML Editor

Answer 1

Code:

mainserver=[]
server1=[]
server2=[]
n=int(input("please enter the no of user for main server"))# input of no of users in server
for i in range(0,n):
    user1=input("enter user name")
    user1=user1.strip().lower()#removing spaces and converting to lower case
    mainserver.append(user1)
n1=int(input("please enter the no of user for server 1"))# input of no of users in server
for i in range(0,n1):
    user1=input("enter user name")
    user1=user1.strip().lower()#removing spaces and converting to lower case
    server1.append(user1)
n2=int(input("please enter the no of user for server 1"))# input of no of users in server
for i in range(0,n2):
    user1=input("enter user name")
    user1=user1.strip().lower()#removing spaces and converting to lower case
    server2.append(user1)
mainserver=set(mainserver)#converting into set
server1=set(server1)#converting into set
server2=set(server2)#converting into set
temp1=mainserver.intersection(server2,server1)#intersecting all three sets and storing to temp
print("users logined to all server",temp1,sep=" = ")

temp3=server1.union(server2)#union server1 and server 2 in temp3
temp2=mainserver.difference(temp3)#substracting temp3 from mainserver and storing to temp2
print("users logined to only mainserver",temp2,sep=" = ")

Output in idle:
