python - regexp and txt file -

i have txt file , regexp , seems regexp working have excess symbols in tail

reg = re.findall(r"source rpm: [ \t\n\r]*(.*?) \s", stdout, re.dotall|re.multiline|re.ignorecase)

and in output have

liblqr-0.4.1-5.src.rpm size gwenhywfar-4.1.0-2.src.rpm size texlive-20110705-1.src.rpm size mandriva-theme-1.4.9-9.2.src.rpm size

or

['liblqr-0.4.1-5.src.rpm\nsize'] ['gwenhywfar-4.1.0-2.src.rpm\nsize'] ['texlive-20110705-1.src.rpm\nsize'] ['mandriva-theme-1.4.9-9.2.src.rpm\nsize']

what "nsize"?

you're doing ungreedy search . ('any character'), including new lines, until space met. new line isn't explicitly space (' ') character, why removing regex create work.

r"source rpm: [ \t\n\r]*(.*?)\s" ^ removed ' '

python regex

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
