Hi,
I need to extract a string after a matching a regular expression.
Whether or not you need re is an issue to be determined.
>>> For example I have the string...
s = "FTPHOST: e4ftl01u.ecs.nasa.gov"
and once I match "FTPHOST" I would like to extract
"e4ftl01u.ecs.nasa.gov".
Just split the string on ': ' and take the second part.
Or find the position of the space and slice the remainder.
so the .* means to match everything after the regex? That doesn't help
in this case
It helps in the case you presented.

MEDIATYPE: FtpPull\r\n', 'MEDIAFORMAT: FILEFORMAT\r\n', 'FTPHOST:
e4ftl01u.ecs.nasa.gov\r\n', 'FTPDIR: /PullDir/0301872638CySfQB\r\n',
'Ftp Pull Download Links: \r\n',
What you show above is a tuple of strings. Scan the members looking for
s.startswith('FTPHOST:') and apply previous answer.
Or if above is actually meant to be one string (with quotes omitted),
split in ',' and apply previous answer.
