Answer:
#section 1
def repeat_words(firstFile, secondFile):
infile_1=open(firstFile,'r')
content1=infile_1.read()
infile_1.close()
#section 2
import string
newContent=""
for char in content1:
newContent+=char.strip(string.punctuation)
newContent=newContent.lower()
newContent=newContent.split()
#section 3
repeated_list=[]
for word in newContent:
if newContent.count(word)>1:
repeated_list.append(word)
#section 4
new_repeat_list=[]
for item in repeated_list:
while item not in new_repeat_list:
new_repeat_list.append(item)
#section 5
outfile=open(secondFile,'w')
for repeat in new_repeat_list:
outfile.write(repeat)
outfile.write('\n')
outfile.close()
infile_2=open(secondFile,'r')
content2=secondFile.read()
infile_2.close()
return content2
# section 6
in_file = 'aa.txt'
out_file = 'cpu.txt'
print(repeat_words(in_file, out_file))
Explanation:
#section 1
it defines a function that takes two arguments. It opens the first argument in the read mode and stores all it's content in a string variable "content1". finally the file is closed.
#section 2
In this section the string module is imported which allows for easy manipulation of string variables.
A new string variable is created that would store the already stripped file.
<em>strip(string.punctuation) </em>strips every character of any leading or trialing punctuation.
<em>lower() </em>converts string to lover case.
<em>split() </em>converts a string to an array of sub-string, i.e an array of words.
#section 3
This section collects all the words in the array and places them in a list.
#section 4
Utilizes a For and a While loop to ensure that no word repeats and stores it in a new list.
#section 5
Opens a new file and writes all the content into that new file and then closes the file.
re-opens the file, reads and returns the content of the file.
# section 6
This is added in order to test the function and print the result
I used your question to test the function and attached the result.
cheers!
Answer:
See explaination
Explanation:
The program code
import java.util.ArrayList;
public class Main
{
public static void main(String[] args)
{
ArrayList<AirlineTicket> tickets = new ArrayList<AirlineTicket>();
//This creates a randomized list of passengers
addPassengers(tickets);
for(AirlineTicket elem: tickets)
{
System.out.println(elem);
}
//This creates a TicketOrganizer object
TicketOrganizer ticketOrganizer = new TicketOrganizer(tickets);
//These are the methods of the ticketOrganizer in action
System.out.println("\nPassengers Ordered by Boarding Group:");
ticketOrganizer.printPassengersByBoardingGroup();
System.out.println("\nPassengers in line who can board together:");
ticketOrganizer.canBoardTogether();
}
//Do not touch this method! It is adding random passengers to the AirlineTicket array
public static void addPassengers(ArrayList<AirlineTicket> tickets)
{
String[] seats = {"A","B","C","D","E","F"};
for(int index = 0; index< 15; index++)
{
int random = (int)(Math.random() * 5);
AirlineTicket ticket = new AirlineTicket("Passenger " + (index+1), seats[random], ((int)(Math.random()*5)+1), ((int)(Math.random()*8)+1));
tickets.add(ticket);
}
}
}
class TicketOrganizer
{
private ArrayList<AirlineTicket> tickets ;
//constructor with parameter as an arraylist of AirlineTicket
public TicketOrganizer(ArrayList<AirlineTicket> tickets)
{
this.tickets = tickets;
}
//methhods to return the arraylist of airlines
public ArrayList<AirlineTicket> getTickets()
{ //re-organize the ticket first
ArrayList<AirlineTicket> tickets_organized = new ArrayList<AirlineTicket>();
for(int i=1; i<=5; i++)
{
for(AirlineTicket ticket: tickets)
{
if(ticket.getBoardingGroup() == i)
{
tickets_organized.add(ticket);
}
}
}
return tickets_organized;
}
//print the tickets based on boardingGroup
public void printPassengersByBoardingGroup()
{
int count = 0;
for(int i=1; i<=5; i++)
{
System.out.println("Boarding Group " + i + ":");
for(AirlineTicket ticket : tickets)
{
if(ticket.getBoardingGroup() == i)
{
System.out.println("Passenger " + ticket.getName());
}
}
}
