[Tutor] Speech recognition, and synthesis
Hello, Are there any Python libraries that deal with speech recognition, and speech synthesis? If so, where are they available, and are there any open source versions? Thanks for any help you can be.

[Tutor] Declaring methods in modules.
Hello, I am working on some stuff, and I would like to be able to write a module which can be imported, and after it's been imported I would like to be able to access it's functions as methods. In other words, if I do the import of module ISPdetector, I want to then be able to make calls like the following - ipAddress = "123.123.123.123" emails = ipAddress.GetEmailAddresses() where GetEmailAddresses() is defined in module ISPdetector. Do I just wite that function in ISPdetector.py as a normally deffed function, or does it have to be part of a class within the module? Thanks for any help you can be.

Re: [Tutor] Declaring methods in modules.
ipAddress = "123.123.123.123"
emails = ipAddress.GetEmailAddresses()
Not exactly sure, what you want, but maybe something like this?
class mystr(str):
def GetEmailAddresses(self):
return [str(self)]
ipAddress = mystr("123.123.123.123")
emails = ipAddress.GetEmailAddresses()

OK, Kind of...

be able to make calls like the following -
ipAddress = "123.123.123.123"
emails = ipAddress.GetEmailAddresses()
This won;t work since ipAddress is a string and you can't add methods to a
builtin type.
But you could define a new special type of string class - an IPstring say -
and
add methods to that. Put that definition in a module and you code becomes:
import ispdetector
ipAddress = ispdetector.IPstring("123.123.123.123")# use module to
access the class
emails = ipAddress.getEmailAddresses() # use the locally created
instance to access methods
where GetEmailAddresses() is defined in module ISPdetector. Do I just
wite that function in ISPdetector.py as a normally deffed function, or
does it have to be part of a class within the module?
If you want to use it as a method it needs to be in a class. You could just
write
it as a function that hass a string parameter in which case your code looks
like:
import ispdetector
ipAddress = "123.123.123.123"
emails = ispdetector.getEmailAddresses(ipAddress) # use the module
and pass the strintg
Whether you need a class or not depends on what the restof your code is
doing
and how data is being handled/stored etc. But we don;t have enough
information
to be sure. My guess is that a class will be handy because you will likely
need
several such methods all acting on common data - which is the definition of
a class!

Can't be done -- in Python, built-in types like strings can't have new
methods added to them, and thank goodness for that! The ability to
monkey-patch builtins is more dangerous than useful.
But you can subclass builtins, as Alan suggested:
# module ISPdetector
class MyString(string):
def GetEmailAddresses(self):
pass
# another module
import ISPdetector
ipAddress = ISPdetector.MyString("123.123.123.123")
emails = ipAddress.GetEmailAddresses()
But that is a strange API design. IP addresses aren't strings, they're
integers, and although they are commonly written in quad-dotted form as
a string, you don't want to treat them as strings. For example,
something like ipAddress.replace('2', 'P') makes no sense.
Also, making GetEmailAddresses a method of an IP address implies that
address *have* email addresses, which is nonsense. People have email
addresses. Computer accounts have email addresses. Particular email
*messages* come from an IP address, but IP addresses don't have email
addresses. A better name would be ipaddress.find_email_from().
So I would suggest the best API is either to create an IP address class
(or better still, don't re-invent the wheel, use one of the fine
existing IP address modules already written), or write functions in the
module and just call them:
import ISPdetector
ipAddress = "123.123.123.123"
emails = find_email_from(ipAddress)
Remember, in Python methods are just syntactic sugar for function calls.
obj.method(arg) is just another way of spelling method(obj, arg).

Re: [Tutor] Declaring methods in modules.
This actually isn't so hard with classes (not instances of the class). Just use setattr(). The first parameter of the function will be the instance, called "self" by convention. This should work with both old and new style There's stuff in the new module for adding stuff to instances, but I haven't played around with it recently. A little fiddling around in the interactive interpreter should clear up anything you're uncertain about, though.

Re: [Tutor] Declaring methods in modules.
Sorry, should have included a concrete example. Although, as the others have said, I'm not sure how it helps with what you (seem) to want to do. 0 % cat bar.py def the_answer(self): return 42 0 % cat foo.py import bar class A: pass setattr(A, '__call__', bar.the_answer) a=A() print a() class B(object): pass setattr(B, '__call__', bar.the_answer) b=B() print b() 0 % python foo.py 42 42 Cheers ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
[Tutor] Sequences of letter
Dear List; I have embarked myself into learning Python, I have no programming background other than some Shell scripts and modifying some programs in Basic and PHP, but now I want to be able to program. I have been reading Alan Gauld's Tutor which has been very useful and I've also been watching Bucky Roberts (thenewboston) videos on youtube (I get lost there quite often but have also been helpful). So I started with an exercise to do sequences of letters, I wan to write a program that could print out the suquence of letters from "aaa" all the way to "zzz" like this: aaa aab aac ... zzx zzy zzz So far this is what I have: letras = ["a","b","c","d","e","f","g","h","i","j","k","l","m","n","o","p","q","r","s","t","u","v","x","y","z"] letra1 = 0 letra2 = 0 letra3 = 0 for i in letras: for j in letras: for k in letras: print letras[letra1]+letras[letra2]+letras[letra3] letra3=letra3+1 letra2=letra2+1 letra1=letra1+1 It goes all the way to aaz and then it gives me this error Traceback (most recent call last): File "/home/administrador/programacion/python/letras2.py", line 8, in print letras[letra1]+letras[letra2]+letras[letra3] IndexError: list index out of range Script terminated. Am I even in the right path? I guess I should look over creating a function or something like that because when I run it I can't even use my computer no memory left -- ¡Saludos! / Greetings!
