Using declarations from types.py

[maggias]

Hi

I am trying to use a python module on a N95 phone that has PyS60 v1.4.2

I am getting a error on this line

if type(rules) not in (NoneType, DictType):

NameError: global name 'NoneType' is not defined

At the top of the module file there is

from Types     import *

that should include everything from the types.py file that is in the PyS60 distribution (I have checked).

I have tried several things to get this to work, for example to include the types like this

from types import NoneType
from types import DictType

(Then I got a error that this could not be imported)

Also to change the input like this

import types

and have the if condition like

if type(rules) not in (types.NoneType, types.DictType):

but then I get

AttributeError: 'module' object has no attribute 'NoneType'

Anyone who knows what I am doing wrong or how this could be fixed.

kindest regards,
Magnus Agust Skulason

It looks ok, but maybe you can change the logic...

import Types

if type(rules) in (types.NoneType, types.DictType):
    pass
else:
    # handle here NoneType and DictType

or maybe

if type(rules) != types.NoneType and type(rules) != types.DictType:
    # handle

or changing negation location

if not type(rules) in (types.NoneType, types.DictType):

Disclaimer: I didn't put any of this through python interpreter, just looked at it and turned some lines around... Anyway, please report how did you finally solve this problem!

Hello everybody ,

@magnus : Look below and find THE SOLUTION :-D


@everybody loving PyS60 : I'm back for PyS60 :-)

from types import *  

rules=[] 
#rules=None
#rules=()
#rules={}

print type(rules)

# deprecated but works with PyS60 (Python 2.2)
# dont use   type(rules) != type(NoneType) !
if type(rules) != type(None) and type(rules) != type({}):
   print u"OK deprecated type 1"

# deprecated but works with PyS60 (Python 2.2)
if (type(rules) is not type(None)) and type(rules) is not type({}):
   print u"OK deprecated type 2"

# recommended for Python >= 2.2 and also PyS60 !
if not isinstance(rules, (NoneType, DictType)):
   print u"OK isinstance"

Hi cyke64,

Thank you very much
if type(rules) != type(None) and type(rules) != type({}):
seems to work

But brought me a similar error on

if type(name) in (ListType, TupleType):

NameError: global name 'ListType' is not defined

am I right to asume that that this should work correctly?

if type(rules) == type([]) or type(rules) == type(()):

I first tried to use
if not isinstance (rules, (NoneType, DictType)):
for the first error, but that still resulted in the error
NameError: global name 'NoneType' is not defined

Thanks again,
Magnus Agust Skulason

hi

any one who knows how to successfully do the following check in PyS60?

if type(obj) == InstanceType:
STATEMENT1
else:
STATEMENT2

fails with a type exception when done like this, I probably have to create some empty Instance and do type() on it. But not sure how that is best done.

Thanks in advance
Magnus

I'm not sure I understand your question, but from what I do understand, you want to check if a variable is of a certain type. If so, try this example:

>>>a=[1,2,3]
>>>isinstance(a, list)
True
>>>b=12.4
>>>isinstance(b, float)
True

So basically for you that would be:

if isinstance(obj, type):
   STATEMENT1
else:
   STATEMENT2

Hope that helps

Hi bogdan.galiceanu,

Thank you, this was what I needed and seems to work perfectly.
