To provide capital growth by investing principally in quoted UK 

smaller companies. 

Investment Approach 

For over 30 years we have followed the same investment style. 

Investing in quality growth companies at a reasonable price. In 

seeking growth, we look to find companies expected to 

produce above average growth in profits and cash returns on 

capital. We look at the companies' quality of management, 

financial position, the industry in which it operates and its 

competitive position.

across the market. Such investment possibilities are not only 

found in the so-called 'old economy' sectors of retailing, 

building & construction and property, but also the 'new

information technology, media, healthcare and biotechnology.

Report compiled by John Basil of County Financial for Robin Becker 

Your investment plan 

Thank you for using Fidelity's Portfolio Planner. This report summarises your Retirement at 65 plan and gives details of funds you are 

thinking of investing in. It also compares the portfolio you have developed with the growth portfolio suggested by the Portfolio 

Planner. The aim of the Portfolio Planner is to help you make informed investment decisions - we hope you have found it useful. At 

the bottom of the page you will find information about the next steps you can take. Please discuss these options with your Adviser to 

determine the the best course of action to take.

Your portfolio strategy 

Our projection assumes that you concentrate on increasing the value of your investment over 

the long term with a growth investment strategy. This would involve choosing funds with the 

potential for strong returns, though you might have to tolerate short-term fluctuations in their 

value.

Your investment growth 

Our projection for your Retirement at 65 investment, is shown in 

the chart on the left. It is for illustrative purposes only and is based 

on the growth you might achieve with our growth strategy. We 

have assumed this will be 7.2% a year, the average level of growth 

achieved by the various forms of investment in this type portfolio 

over the past 100 years. There is no guarantee that this level of 

perfromance will be repeated in coming years, and if markets fall 

you may not get back the amound you invest. 

We have chosen such a long period, covering both world wars and 

the depression of the 1930's, so that the figures are not distorted 

by the high returns that stockmarket investments have achieved in 

recent decades. Typical central bank forecasts of inflation for the 

years ahead are 3.5%. We have therefore taken this from the 7.2% 

growth rate and based our calculations on a real rate of return of 

3.7% a year.

Your next steps... 

Choose your funds 

If you decide you would like to use the Retirement Plan 

portfolio as a basis for your Retirement at 65 investment, you 

are now in a position to choose your funds. To make this as 

straightforward as possible we have linked the Portfolio 

Planner to our fund selection tool. This will automatically 

search through the hundreds of funds in our investment 

superstore FundsNetwork to find the ones from each category 

in our suggested portfolio. You can then draw up a short list of 

funds, read fact sheets on the ones you are considering and 

create your own portfolio fund by fund. 

You will then be able to print out a fuller version of this report, 

which incorporates your chosen funds and shows how the 

portfolio you have created compares with the suggested 

growth portfolio. 

When you have made your choice you can invest either online 

or by post via your Adviser. 

Suggested growth portfolio 

This pie chart shows a portfolio that you might want to consider as 

a suggestion for your Retirement at 65 investment. The Portfolio 

Planner cannot give an opinion on which funds and types of 

investment are right for your particular circumstances, but this 

model may help you make your decision. 

The primary aim of this portfolio is to achieve significant long-term 

growth without investing in those sectors that are usually 

considered to present the highest levels of risk. Only a small part 

of the portfolio is kept in relatively low-risk bonds. The rest is 

invested in equity funds. The majority of these focus on the UK, 

but about a third of the overall portfolio is invested internationally 

in order to benefit from growth potential in other parts of the 

world. With this type of portfolio you need to be prepared for 

short-term fluctuations in the value of your holdings. 

Fine-tune your investment plan 

You can update the details of your Retirement at 65 investment 

plan as often as you want. Simply speak to your Adviser who will 

be able to review your portfolio strategy for you. 

Need extra help 

Your Adviser will be able to assist you throughout the 

decision-making process and recommend the portfolio strategy 

best suited to your investment needs. Please also bear in mind 

that the suggested portfolios may change, so you may like to 

review your strategy regularly with your Adviser. 

We cannot give you advice on your investments, but if you call us 

on 0800 995511 we can give you any general information you 

may need about FundsNetwork's products and services. Please 

feel free to call us any day of the week, between 8am and 6pm.

Python Referenz 

Python Referenz 

3 Typen und Objekte 

Alle Daten eines Python-Programmes basieren auf dem Konzept eines Objektes. Objekte umfassen 

grundlegende Datentypen wie Zahlen, Zeichenketten, Listen und Dictionaries. Es ist auch möglich, 

benutzerdefinierte Datentypen in Form von Klassen oder Erweiterungstypen zu erstellen. Dieses Kapitel 

beschreibt das Objektmodell von Python und gibt eine Übersicht der eingebauten Datentypen. Kapitel 4, 

»Operatoren und Ausdrücke«, beschreibt weitere Operatoren und Ausdrücke. 

3.1 Terminologie 

Jedes Datum im Speicher ist ein Objekt. Jedes Objekt hat eine Identität, einen Typ und einen Wert. 

Wenn man z.B. a = 42 schreibt, wird ein Ganzzahl-Objekt mit dem Wert 42 erzeugt. Man kann die 

Identität eines Objektes als Zeiger auf einen Platz im Hauptspeicher betrachten. a ist der Name dieses 

Platzes. 

Der Typ eines Objektes (der seinerseits eine spezielle Art von Objekt ist) beschreibt die interne 

Repräsentation des Objektes wie auch die Methoden und Operationen, die es unterstützt. Wird ein 

Objekt eines bestimmten Typs erzeugt, so wird dieses Objekt manchmal als eine Instanz dieses Typs 

bezeichnet (obwohl eine Instanz eines Typs nicht mit einer Instanz einer benutzerdefinierten Klasse 

verwechselt werden sollte). Nachdem ein Objekt erzeugt wurde, können dessen Identität und Typ nicht 

mehr verändert werden. Falls dessen Wert jedoch verändert werden kann, so sagt man, das Objekt ist 

veränderlich. Falls der Wert nicht verändert werden kann, so spricht man entsprechend von einem 

unveränderlichen Objekt. Ein Objekt, das Verweise auf andere Objekte enthält, bezeichnet man als 

Container oder Sammlung. 

Zusätzlich zum Wert, den sie repräsentieren, definieren viele Objekte eine Anzahl von Datenattributen 

und Methoden. Ein Attribut ist eine mit dem Objekt assoziierte Eigenschaft oder ein Wert. Eine 

Methode ist eine Funktion, die eine gewisse Operation auf einem Objekt ausführt, sobald sie angestoßen 

wird. Attribute und Methoden werden mit dem Punkt-Operator (.) angesprochen, wie im folgenden 

Beispiel gezeigt wird: 

a = 3 + 4j 

r = a.real 

# Erzeuge eine komplexe Zahl. 

# Hole den Realteil (ein Attribut). 

b = [1, 2, 3] # Erzeuge eine Liste. 

b.append(7) # Füge ein neues Element an b 

# mit der Methode 'append' an. 

3.2 Identität und Typ von Objekten 

Die eingebaute Funktion id() gibt die Identität eines Objektes als ganzzahligen Wert zurück. Dieser 

entspricht normalerweise dem Platz des Objektes im Hauptspeicher, was aber abhängig von der 

Implementierung ist. Der Operator is vergleicht die Identität zweier Objekte. Die eingebaute Funktion 

type() gibt den Typ eines Objektes zurück, z.B: 

# Vergleiche zwei Objekte. 

def compare(a, b): 

print 'Die Identität von a ist ', id(a) 

print 'Die identität von b ist ', id(b) 

if a is b: 

print 'a und b sind dasselbe Objekt.' 

if a == b: 

print 'a und b haben den gleichen Wert.' 

if type(a) == type(b): 

print 'a und b haben den gleichen Typ.' 

Der Typ eines Objektes ist seinerseits ein Objekt. Das Standardmodul types beinhaltet die 

Typ-Objekte für alle eingebauten Typen und kann für eine Typ-Prüfung verwendet werden, z.B. so: 

import types 

if isinstance(s, types.ListType): 

print 'Ist eine Liste.' 

Benutzerdefinierte Funktionen sind aufrufbare Objekte, die auf Modulebene mit der Anweisung def 

oder der Operation lambda erzeugt werden (Funktionen, die innerhalb von Klassen definiert werden, 

nennt man Methoden. Sie werden in Kürze beschrieben). In Python sind Funktionen Bürger erster 

Klasse, die genauso behandelt werden wie alle anderen Python-Objekte. Daraus folgt, dass man sie an 

Variablen zuweisen oder sie in Listen, Tupel oder Dictionaries unterbringen kann, wie im folgenden 

Beispiel gezeigt wird: 

def foo(x, y): 

print '%s + %s ist %s' % (x, y, x+y) 

# Weise an eine neue Variable zu. 

bar = foo 

bar(3, 4) 

# Ruft 'foo' auf, oben definiert. 

# Setze foo in einen Container. 

d = {} 

d['callback'] = foo 

d['callback'](3, 4) # Ruft 'foo' auf. 

Eine benutzerdefinierte Funktion verfügt über folgende Attribute: 

Attribut(e) 

f.__doc__ oder 

f.func_doc 

f.__name__ oder 

f.func_name 

f.func_code 

f.func_defaults 

f.func_globals 

Beschreibung 

Dokumentations-String 

Funktionsname 

Byte-übersetzter Code 

Tupel mit voreingestellten Argumenten 

Dictionary, das den globalen Namensraum 

definiert 

Methoden sind Funktionen, die nur auf Objektinstanzen operieren. Üblicherweise werden Methoden 

innerhalb einer Klassendefinition definiert: 

# Eine Schlange von Objekten, nach Prioritäten sortiert. 

class PriorityQueue: 

def __init__(self): 

self.items = [ ] 

# Liste von (priority, item) 

def insert(self, priority, item): 

for i in range(len(self.items)): 

if self.items[i][0] > priority: 

self.items.insert(i, (priority, item)) 

break 

else: 

self.items.append((priority, item)) 

def remove(self): 

try: 

return self.items.pop(0)[1] 

except IndexError: 

raise RuntimeError, 'Schlange ist leer' 

Ein ungebundenes Methodenobjekt ist eine Methode, die noch nicht mit einem speziellen Instanzobjekt 

assoziiert wurde. Die Methoden in einer Klassendefinition sind solange ungebunden, bis sie einem 

speziellen Objekt hinzugefügt werden, z.B.: 

m = PriorityQueue.insert # Ungebundene Methode. 

Um eine ungebundene Methode aufzurufen, übergibt man eine Objektinstanz als erstes Argument: 

pq = PriorityQueue() 

m = PriorityQueue.insert 

m(pq, 5, "Python") 

# Ruft pq.insert(5, "Python") auf. 

Ein gebundenes Methodenobjekt ist eine Methode, die bereits mit einem speziellen Instanzobjekt 

assoziiert wurde, z.B.:
