[Jython-users] Jython (Python) syntax question

[<cl...@br...>]

Dear colleagues, 

porting a Drools semantic (rules definition language) into a Jython code. 
The code throws a syntax error at the following line: 

TRUE = 1
FALSE = 0 
..
self.salience = 30 
self.no-loop = TRUE 

Error:  Syntax error can´t assign to operator. 

Looks like the Jython acts like a Python interpreter, rejecting the right 
side of the assignment statement, thinking "self.no-loop" is an 
expression. 
Indeed inside Java DRL, the "no-rule" is an attribute, like this <rule 
name="rule1" salience="30" no-rule="true"> 

Any idea how to fix the syntax error? 

Regards, 
Claude

"no-rule" is not a valid python identifier; it contains the "-"
operator, and so is interpreted as an expression, like so

self.no - loop = TRUE

Use "_" instead; you should have no problem with the following

self.no_loop = TRUE

HTH,

Alan.

Maybe setattr(self,'no-loop',TRUE)

Re: [Jython-users] Jython (Python) syntax question / thanks

Dear Jeff, 

setattr(self,'no-loop',TRUE)

The Jython interpreter did accept it as a valid syntax. That hint was 
really ZEN ! Thanks.
