Python Program:
Write a program which controls a metro train and that keeps track of stations and who gets on and off. Design and implement a class called train, which has at least the following:
- At least the following attributes (you can include others):
metroID
stationNum
which keeps track of the station that the train is at.
iii.
direction
which keeps track of the direction the train is travelling in.
passTotal
which keeps track of the number of passengers currently on the train.
A
default constructor
which sets the
metroID
to a random number between 1 and 1000, the station number to 0, the direction (int), and the
passTotal
to 0 (train is empty).
A constructor
with one parameter; the parameter is the metro id. The constructor assigns the passed integer to the
metroID
attribute; the rest of the attributes are set as described in the default constructor.
- Accessor methods for each attributes.
- Mutator methods for each attributes.
nextStation(int lastStation) which determines the next station the train is to go to, and changes the direction of the train when necessary. This method should return a integer value which will specify the action that needs to be done: passengers leaving, passengers boarding or passengers getting off and boarding
- A string representation method (str) will return in a string the
metroID, the current station number, the direction the train is travelling in as well as the number of passengers on the train.
Using all of these methods may not be necessary in your design but they must be present either way (can also be used to add something interesting).
Your program driver should:
- Display a welcome message
- Ask the user for the number of metro stations. There should be at least 3 stations. Make sure the user enters a number ≥ 3, if not keep asking until they enter at least 3. You may as well ask the user for input to name the stations.
- Create a Train object using the default constructor.
- As long as the user wants:
- Advance the train to the next station. At each station, using a random number generate the number of people who will disembark the train (where applicable), and the number of people who have arrived wishing to embark on the train (where applicable). Rules:
- If the metro train is at the 1st station in any given direction, there will only be people waiting to get on as the train is empty.
- If the metro train is at the last station, all passengers must get off and no one can get on until the train turns around.
- Any other station, there are people waiting to get on (a max of 300), and some people will get off the train (can’t have more people getting off than there are people on the train).
-The metro train can hold a maximum of
250
people at any given time
- If the number of places available on the train, after people leave is less than the number of people waiting to get on, some people will be left waiting on the platform for the next train.
- Keep track of the number of people who did not get on the train, as they will try and embark on the next train.
- Display the Train ID, the station that the train is leaving and the number of passengers. As well:
-indicate the number of people who got off the train
-the number of people who were left behind at this station the last time and are hoping to embark the train this time
-the new people who arrived on the platform
-the number of people who actually got on the train
-the number who are left behind on the platform because the train was full this time.
Include the train id, the station number and the direction the train is travelling in (info that is displayed when output a train object).
- Ask the user if they would like to continue following the metro
- If yes, continue to next station and repeat the process
- If no, quit and end the program with a closing message.
The metro train travels from one end of the line to the other. When it reaches the end in either direction, all passengers must get off. The train turns around and starts again with an empty train from the same station heading in the opposite direction.
Please see the pdf attached in the zip folder to have an example of what the desired output would look like for this application. Your output does not have to be identical to this but rather it is a guideline, so follow the main features represented. The logical part still has to be correct in terms of keeping track of the train and passengers.
Additional features: Part of your grade will be to implement some extra feature of your own choosing, some potential ideas to use include: multiple trains, additional directions (north, south), compare trains, gui, additional lines (blue, green, yellow) etc… Two points for two different ideas implemented that notably modifies your application. You may add a creative idea of your own and if you are unsure about an idea, send an MIO to confirm and validate your thoughts and to discuss further the chosen features to be added.
