learning to program with Python

[Ricardo]

Hi, my name is Ricardo and i'm learning to program in Python with
version 2.3.3, i'm also using the latest version of PythonWin(163) but
i'm trying to do it with a book (Written in Portuguese) that covers the
version 2.1, and of course i'm having a problem. The code in wich i'm
having problems is as follows:

class Gato:
"um felino domesticado"
def __init__(self, sexo, corPelo=None):
self.sexo = sexo
if corPelo != None
self.corPelo = corPelo
def miar(self):
if self.sexo == "m":
return "MIAU"
else:
return "miauuuu"
the book says that it should be done like this, but when i finnish the
5th line(if corPelo != None) and press ENTER, it gives me the error:

Traceback ( File "<interactive input>", line 5
if corPelo != None
^
SyntaxError: invalid syntax

I hope someone can help me?
Thanks in advance anyway.

Ricardo

if corPelo != None
self.corPelo = corPelo

Oi Ricardo, tudo bem?

I see at least two problems here. Python requires brackets around the 'if'
comparison, and a colon at the end of the if statement. Try re-writing
your statement as:
if (corPelo != None):
self.corPelo = corPelo

Boa sorte!

The colon is needed, yes... but not the parentheses...

No, Python doesn't require parenthesis or brackets around the
comparison. Any expression can have optional parenthesis.

if corPelo != None:
self.corPelo = corPelo

is enough.
