Newcomer has a problem with ply....

[akeshmiri]

Hi,
Sorry but I could not find any other place to write about my issues.
I am new in Compiler and trying to learn using PLY, it seems very easy and handy, so thank you for you great project. :)
The question is that i cannot made the correct parser for the case when we have something like the following code:

BG = 12 mg/dL
timeout = None

the part which is related to this code in parser is

reserved = {
'bg' : 'BG',
'timeout' : 'TIMEOUT',
}

t_STRING = r'[a-zA-Z]\w_'
t_BG_VALUE = r'\d+\s_mg\s_/\s_dL'
t_TIMEOUT_VALUE = 'None|(30\s_sec)|([1-3]\s_min)'''

def p_configuration_step(t):
'''configuration_step : BG ASSIGN BG_VALUE
| TIMEOUT ASSIGN TIMEOUT_VALUE'''
node = ASTNode(NodeTypes.ConfigurationStep, t[1])
node.insertChild(0, ASTNode(NodeTypes.ConfigurationValue, t[3]))
t[0] = node

what ever I do I got

Syntax error on timeout at line 1

Please advice....
