It can make use of the standard logging parameters and/or take custom input. The use of JSON in the log file allows for easy filtering and processing.</p>

<p style="color: grey"> Python recipe 578283 by <a href="/recipes/users/4183853/">wei.Liu</a> (<a href="/recipes/tags/database/">database</a>). </p> <p>Sometimes you get an Excel spreadsheet (say, from the marketing departement) and you want to read tabular data from it (i.e. a line with column headers and lines of data). There are many ways to do this (including ODBC + mxODBC), but the easiest way I've found is this one : provide a file name and a sheet name, and read the data !</p>

When you modify some files, script automatically see what files was modified since the last update, and clear cache on CloudFront only for them.</p> <p>Usage: script.py data_dir [index_file] [dir_prefix] </p> <p>data_dir - path to directory with uploaded data</p> <p>index_file - path to files index</p> <p>dir_prefix - needed if you data_dir path is different from url at CloudFront.For example: Your data_dir is '/data' but url at CloudFront is <a href="http://url.com/social/data/" rel="nofollow">http://url.com/social/data/</a> so dir_prefix will be '/social/data/'</p>

<p style="color: grey"> Python recipe 280653 by <a href="/recipes/users/1783111/">Ben Young</a> (<a href="/recipes/tags/database/">database</a>). Revision 2. </p> <p>Sometimes it can be hard to work out a way of efficiently representing a tree in the database. Combining modified preorder tree traversal with a parent child model allows most common queries to be represented in a single sql query. This example uses MySQLdb, but can easy be changed to use any DBI compatable module.</p>

Lowlevel security is done by checking on remote ip address (which is not secure but blocks)</p>
