java - What is arithmetic left shift of 01001001? -

i think 00010010 i.e. tries maintain sign bit is

on other hand, logical left shift 1 pos 10010010

for left shift, arithmetic , logical shift same.

the difference right shift only, arithmetic right shift re-create old msb new msb after having shifted, keeping negative number beingness converted positive when shifting.

wikipedia has more detailed explanation.

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...
