<p style="color: grey"> Python recipe 580696 by <a href="/recipes/users/4189558/">Tomas Nordin</a> (<a href="/recipes/tags/database/">database</a>). </p> <p>This fork assumes a desire for limited selection of field names. With huge files this might be necessary on some machines.</p> <p>Also, assuming that the meaning of null in a dbf file means zero might be a mistake, so the fork adds an argument nullreplace as way to choose what to replace null with. Null is sometimes used to mean missing value. This change is decoupled from the selective names feature.</p>

The new class will have a method for encoding to json and a method for decoding from json. The classes are then loaded into an encoder object and a decoder object that are hooked into the standard json loads and dumps functions.</p>

The lru_timestamp function should be called with the same refresh_interval value for a given @lru_cache decorated function. The returned timestamp is for the benefit of the @lru_cache decorator and is normally not used by the decorated function.</p> <p>Positional arguments: refresh_interval -- in minutes (default 60), values less than 1 are coerced to 1, values more than 1440 are coerced to 1440</p>

Revision 2. </p> <p>A GUI built around wxPython in a way that will allow you to add to this application other forms and functionalities. The main DialogBox is to create,in a fast way, Sqlite3 databases that are used for web or applications development. In order to work properly, save the script in a separate directory.There is also more; each time you create a database a text file named "CreationLog.txt" will be created (for the first time you use the application or if it is not there) and updated, describing when and where was your database created and with what SQL query. I am pleased to receive all the suggestions and improvements on this site or to my e-mail directly if this is convenient to you.</p>
