how to make '.' a string

[dynamo]

i want to add '.' to another string .However the interpreter does not seem to see '.' as a string but something to do with the instancemethod.Does anyone know how to use a dot as a string.I have tried usind str to convert it i keep getting the same error:

Traceback<most recent call last>
     File "C:\Python25\CalculatorBlueprint.py",line 194 in handler
                b=a+d
    TypeError:unsupported operand type(s) for +:'instancemethod' and 'str'

Can anyone help?

Same way as any other character on the keyboard: with quotes
>>> print "Hello world" + "."
Hello world.
>>>

This is the problematic part of the code:

 if i==31:
            a=self.txt.GetValue
            d='.'
            b= a+ d
            self.txt.SetValue(b)

I gave the error message earlier.

i can guess your problem. I believe when you have a SetValue() method in your class, you will also have GetValue(). BUT, you have assigned 'a' to an instance because you forgot about (). The correct way should be something like
...
a = self.txt.GetValue()
...
the depending on what GetValue() returns (hopefully its a str type), then you can concat with your dot.

if you want to read Word files, you can use Win32 COM. For readling html files, you can use urllib2 or urllib. If you want to simulate a browser, you can use the webbrowser module.
