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.
OK, Kind of...
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()
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!
