Re: Question on re.IGNORECASE

OK, I got it.

- The re module search function syntax is:

search( pattern, string[, flags])

where re.IGNORECASE is a valid flag.

- The RE Object search method syntax is:

search( string[, pos[, endpos]])

where "The optional second parameter pos gives an index in the string
where the search is to start; it defaults to 0"

It turns out that re.IGNORECASE has the value
2.

Am I the only person bitten by this?

Hi,

I'm having some problems with basic RE in python. I was wondering
whether
somebody could provide a hint on what's going wrong with the following
script. Comments are included.

TIA.
