Hi,
I got the the following syntax error in comparison:
 File "/usr/local/work/myparser.py", line 85
   if ( (m=self.macro_parser.match (d)) != None ):
          ^
SyntaxError: invalid syntax
How can I get around wtih this? I don't want to break down this 
comparison in two steps.

Sorry, you have to.  Assignment statements are not expressions in Python.  

    m = self.macro_parser.match(d)
    if m:
        xxx
This is very bad to me, I will need to write some cumbersome syntax as 
follow:
       for d in self.data:
            m = self.macro_parser.match (d)) != None ):
            if (m == None):
               m_nat = self.a_parser.match (d)
               if (m_a == None):
                  m_rdr = self.b_parser.match (d)
                  if (m_b == None):
                      m_c = self.c_parser.match (d)
                      if (m_c == None):
                         m_d = self.d_parser.match (d)
                         if (m_d == None):
                            m_e = self.e_parser.match (d)
                            if (m_e == None):
 				.....


You know the outer parentheses are not necessary, right?
