performance - Fastest algorithm to calculate the Normalized and Engineering Scientific notation of a number -

test case :

35000

-> normalized scientific notation of number 3.5 * 10e4

-> engineering science notation 35 * 10e3

a simple algorithm maintain dividing number 10 until notations required. mean algorithm o(number of zeros). can better?

the classic paper on subject of printing human-friendly representations of floating point numbers can read here. it's much complex discussed code in reply here.

How do I check if an insert was successful with MySQLdb in Python? -

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...
