Writing file using configparser

[William Manley]

According to what I read in the ConfigParser module, this should work, but it doesn't. Can anyone point out what I'm doing wrong?

    def writeinifile ( self, FILE='P:/INI/test.ini', SECTION='Testsection', OPTION='Item', VALUE='wheeee' ):
        p = ConfigParser()
        p.read(FILE)
        if not p.has_section ( SECTION ):
            p.add_section(SECTION)
        p.set(SECTION, OPTION, VALUE)
        p.write(FILE)

The error I keep getting:

Python 2.5 (r25:51908, Sep 19 2006, 09:52:17) [MSC v.1310 32 bit (Intel)] on win
32

>>> from INIfile import INI
>>> I = INI()
>>> I.writeinifile ( SECTION='Sectio n' )
Traceback (most recent call last):

File "C:\Python25\li b\ConfigParser. py", line 369, in write
fp.write("[%s]\n" % section)
AttributeError: 'str' object has no attribute 'write'
>>>

To me it looks like it is something wrong in the ConfigParser code, But I'm sure thats just foolish arrogance getting to me, because I of course keep insisting I'm right. :)

Oops, sorry, Realised I didn't post the entire code.

from ConfigParser import ConfigParser

class INI:
    def getinifile ( self, FILE, SECTION, OPTION, DEFAULT ):
        p = ConfigParser()
        p.read(FILE)
        if p.has_section ( SECTION ):
            #print 'Has Section'
            if p.has_option ( SECTION, OPTION ):
                #print 'Has Option'
                Value = p.get ( SECTION, OPTION ).strip()
            else:
                Value = DEFAULT
        else:
            Value = DEFAULT
        return Value
    def writeinifile ( self, FILE='P:/INI/test.ini', SECTION='Testsection', OPTION='Item', VALUE='wheeee' ):
        p = ConfigParser()
        p.read(FILE)
        if not p.has_section ( SECTION ):
            p.add_section(SECTION)
        p.set(SECTION, OPTION, VALUE)
        p.write(FILE)

William,
Would you also post your file 'test.ini'? That would help. Thanks.

a first look at the code, the FILE parameter is defined as a string. and according to the docs, the write() method argument is supposed to be a file object. I suppose you need to use a file pointer instead. something like this when you initialise a file object pointer.

f = open("file","w")  # f is a file object now.

ghostdog74 is correct as usual! I played with it some:

>>> fp = open(r'H:\TEMP\temsys\TEST.INI')
>>> p = ConfigParser()
>>> p.readfp(fp)
>>> p.set('X Axis', 'usage', '0x90')
>>> p.items('X Axis')
[('name', 'X AXIS'), ('linedata.1', '(310,60),(310,76),(268,76)'), ('usage', '0x90'), ('calloutmax.1', '(296,17),(386,59)'), ('type', '0x2'), ('usagepage', '0x1'), ('align.1', 'BL')]
>>> p.write(open(r'H:\TEMP\temsys\TEST1.INI', 'w'))
>>>

thanks for verifying :-).

Wow, I love you guys, thanks. It works great. :)
