Here is my question : is it possible using inheritance, to have a parent class with a DEFAULT argument that would automatically be assigned to an object (whether it is a child or parent class object) BUT if an object (using the child class), wants to over-write that attribute, it can do that as well??  The child would be using super and inheritance.  Just some sample code below to show what I  mean.

WORKS : As soon as I create an object, such as a= F1(), since there is already a default argument, it assigns the object as  sick="flu".  If I create another object b=F1("mumps"), it will be over-written.

DOESN'T WORK (yet) : If I create a child class c=F2("bed rest"), I want to take the default of sick="flu" from the parent since it is inheriting that.  Right now, it tells me it is missing an argument  

WORKS: If I want to over-write the parent argument of "sick" with an object using the Child class d= F2("measles","doctor"), it will also do this.


class F1(object):   def __init__(self, sick="flu"):    self.sick=sick class F2(F1):   def __init__(self, sick, cure):    super(F2, self).__init__(sick)    self.cure=cure a = F1() print(a.sick) b = F1("mumps") print(b.sick) c = F2("bed rest") print(c.sick) print(c.cure) d= F2("measles","doctor") print(d.sick) print(d.cure)

Hopefully that makes sense.  Thanks in advance.

I know that I can get one text entry box with GUI using  : msg = turtle.textinput("your login", "What is your login")

But I was wondering if there is a way to create multiple text entry boxes in the same window?

I was informed I should use

print(getattr(myobject, a)())

I can see it works, but I was hoping there was another way

Ok, I tried this :

import random output1="output1" output2="output2" my_list=[output1, output2] index = random.choice(my_list) class test:    def output1(self):        return "output 1"    def output2(self):        return "output 2" myobject = test() print(myobject.index())

I was going to create a  list of all of the functions and pick randomly through the list, but that doesn't work because the function names are local,

Thanks for trying, but yes I need it in python.

Is there a way to call a random method (out of a set of methods) in a class purposefully?

I will post the code when I get it closer to being somewhat correct.  I find for myself, working this way is more productive, I hope people don't mind.  I have put more descriptive pseudo-code below :
Ok, I changed the sentinel value and I am not going to be using that anymore.  Instead I am going to ask the user if they want to keep adding to the database, if no, then break, if yes, then continue.  

Another problem!  

can't assign to a function call


count= 0

class car
initialize all of the values and put self so they are available to the entire class
def __init__(self, model...)
 self.model=model etc
 self.serial = serial
 self.doors=doors



while loop
input model =what is the model
input serial = what is the serial
input doors = how many doors
count = count + 1
#create the instance/object
mycar (count) = car(model, serial, doors)

input do you want another car in the database?
if yes
 continue
if no
 break

The issue is that when creating an object/instance, python won't let me use this syntax of having -- mycar(count) which would give me multiple objects (mycar1, mycar2, mycar3 etc) with the count variable.  I am not sure why.

I was thinking about something like this :

While quit is not entered
enter your name (quit to exit)
enter your age (quit to exit)
enter your id (quit to exit)


All of this information gets passed into the class via __ini__
The initial entering of information isn't in a class

I am testing out some basic Object Oriented Programming in Python.  The basics:

User enters a name
While loop with a sentinel value of "quit" will continue entering names until the sentinel value is reached
The object is created with the inputted value (NAME and until a sentinel value is entered)
the object is then printed out using the constructor __str__
in my solution ( I am saying this because someone might have a work around that doesn't include the following below)
I want to use __init__
I want to use __str__
I want to use a while loop with a sentinel value

EXPLANATION:
I want to have the user enter in their NAME using a while loop, with "quit" being the sentinel value that breaks the loop.  Once the name is entered, an object is created and it is passed into a constructor def __ini__ (self, name) and then I have them return a string value using __str__ for the name entered.
The issue I am having is that when i enter the sentinel value of QUIT, it gets initialized as the name and printed out.  How can I get around this?  I hope this makes sense.

Ok I got part of it working on my own, now I can take out books from the series (Denny) and take out individual books (Bill).  But I am stuck on Denny taking individual and a series at the same time.

class Account(object):    def __init__(self, name, accountNumber):        self.personname = name        self.accountNumber = accountNumber        self.booksCheckOut = []    def checkout(self, title):        self.booksCheckOut.append(title)    def checkOutSeries(self, seriesname):        for i in range(g):            self.booksCheckOut.append(seriesname)    def __str__(self):        if x == 1:            print("a series of books")            printout = (self.personname + " is checking out ") + "\n"            for i in range(g):                printout = printout +(self.booksCheckOut[i].seriesname + "#" + str(i+1)+ "\n")            return printout        else:            print("not a series")            printout = self.personname + " has checked out "            for i in range(len(self.booksCheckOut)):                 printout = printout + (str(i+1) + ") " + self.booksCheckOut[i].bookname + ", ")            return printout class Book:    def __init__ (self, name, IDnumber):        self.bookname = name        self.IDnumber = IDnumber        global x        x = 0 class Series:    def __init__(self, seriesname, numberofbooks):        self.seriesname = seriesname        global g        g = numberofbooks        global x        x = 1 denny = Account("Denny", 123) bookseries1 = Series("Maze Runner", 3) denny.checkOutSeries(bookseries1) #book1 = Book ("Motorcyle Maintenance", 45) #denny.checkout(book1) print(denny) bill = Account("Bill", 123) book2 = Book("Far cry", 34) bill.checkout(book2) print(bill)

I am trying to use Classes to instantiate an object.  I am entering in the name of a book and the number of books in the series.  I want to take that info and append it to a list.  Any ideas?
For example :

title - # books
Maze Runner, 3

I want to use the range of 3 to have it add the books to a list - such as
maze runner #1
maze runner #2
maze runner #3

I thought I had it correct using the __str__ but I have gone wrong somewhere (probably many places).

class Account(object):    def __init__(self, name, accountNumber):        self.personname = name        self.accountNumber = accountNumber        self.booksCheckOut = []    def checkOutSeries(self, seriesname):        for i in range(g):            self.booksCheckOut.append(seriesname)    def __str__(self):        print (self.personname + " is checking out ")        print (self.booksCheckOut) # why isn't this printing as a string????????        for i in range(g):                printout = (self.booksCheckOut[i].seriesname + "#" + str(i+1))        return printout class Series:    def __init__(self, seriesname, numberofbooks):        self.seriesname = seriesname        global g        g = numberofbooks denny = Account("denny", 123) bookseries1 = Series("harry potter", 7) # number of books in the series denny.checkOutSeries(bookseries1) # instantiating the series and using the class print(denny)

Yes I see what you mean.  Only in recursion does it not recreate a fresh copy, right?
Can you explain what scope is please?

I am work on a function that, depending on what the user inputs, will continually update and total.
For example, the user inputs the number 6, and then the user inputs the number 3 and lastly inputs the number 2 - I want it to go through the function for each individual input and add to the running total.  Something similar to this.  Do I need to put the numbers in a list as they are inputted instead?

def add(total): final = final + total num1 = input("Would is the first number?") add(num1) num2 = input("Would is the first number?") add(num2) num3 = input("Would is the first number?") add(num3)

And if it only returns "1", then the answer should be "1", not 120.
