While this works when you are only combining flags, the general way of handling
flags (= bit-fields) is with the three bit-wise operators '^', '&' and '|'.

These flags are combined using the bit-wise OR operator.

re.compile(matsearch, re.VERBOSE|re.IGNORECASE)

MatSearch = re.compile(matsearch, re.IGNORECASE + re.VERBOSE)

You need to OR them together:

re.compile(matsearch, re.VERBOSE | re.IGNORECASE)

re.IGNORECASE and re.VERBOSE

2005-07-18 Thread Jeremy 
I am using regular expressions and I would like to use both
re.IGNORECASE and re.VERBOSE options.  I want to do something like the
following (which doesn't work):

matsearch = r'''^\ {0,4}([mM]\d+) '''
MatSearch = re.compile(matsearch, re.VERBOSE, re.IGNORECASE)

Does anyone have any suggestions?
Thanks,
Jeremy
