Question

I am trying to take a java class and rewrite it in python. here is what i have so far:

class Book:
__bookTitle=''
__bookAuthor=''
__bookYearPub=''
__
  
def __init__(self):
self.__bookTitle=bookTitle
self.__bookAuthor=Author.getName()
def getAuthor():
return Author.getName()
def getPublisher():
return Publisher.getName()
def getYearPub():
return self.__bookeYearPub()
def setYearPub():
self.__bookYearPub=bookYearPub
def getLocationCode():
return self.__locationCode
def getTitle():
return self.__bookTitle
def setTitle():
self.__bookTitle=bookTitle
#def toString():

here is the original java class:

/**
* Represent books in our library
*/
public class Book {

//Todo:
// Book has a title, a location (string) a year of publication (int) a single author and a single publisher.
private String title;
private String locationCode;
private int yearPub;

private Author author;
private Publisher publisher;

/**
* Initializes the book
* @param title book's title
* @param location book's location in the library. it's usually a code like G70.212.R54
* @param yearPub year of publication
* @param author author object.
* @param publisher publisher object.
*/
public Book ( String title, String location, int yearPub,Author author, Publisher publisher){
//Todo: #1 Initialize the book attributes.
this.title =title;
this.locationCode = location;
this.yearPub = yearPub;

this.author = author;
this.publisher = publisher;
}

public Book (String title, String location, int yearPub){
//Todo: #2: initialize attributes. Author and publisher should be set to null.
// reuse as much as possible!

}

public Author getAuthor() {
//Todo: #3
return author;
}

public Publisher getPublisher() {
//Todo: #4
return publisher;
}

public int getYearPub() {
//Todo: #5
return yearPub;
}

public void setYearPub(int yearPub) {
//Todo: #6
this.yearPub = yearPub;
}

public String getLocationCode() {
//Todo: #7
return locationCode;
}

public void setLocationCode(String locationCode) {
//Todo: #8
this.locationCode = locationCode;
}

public String getTitle() {
//Todo: #9
return title;
}

public void setTitle(String title) {
//Todo: #10
this.title = title;
}

/**
* The toString method converts an object to a string. It is used to display the object in a println call.
* @return
*/
public String toString(){
//Todo: #11
// should show: "A book called '<title>' written by '<author name>' and published in <year> by '<publisher name>'"
// e.g. "A book called 'intro to java' written by 'John' and published in 2005 by 'Pearson'
return String.format("A book called '%s' written by '%s' and published in %d by '%s'", title, author.getName(), yearPub,publisher.getName());
}
}

class Book:
    def __init__(self, title, locationCode, yearPub, author=None, publisher=None):
        self._title = title
        self._locationCode = locationCode
        self._yearPub = yearPub
        self._author = author
        self._publisher = publisher

    def get_title(self):
        return self._title

    def get_locationCode(self):
        return self._locationCode

    def get_yearPub(self):
        return self._yearPub

    def get_author(self):
        return self._author

    def get_publisher(self):
        return self._publisher

    def set_title(self, title):
        self._title = title

    def set_locationCode(self, locationCode):
        self._locationCode = locationCode

    def set_yearPub(self, yearPub):
        self._yearPub = yearPub

    def __str__(self):
        return "A book called '%s' written by '%s' and published in %d by '%s'" % (
            self._title, self._author.get_name(), self.get_yearPub(), self._publisher.get_name())
