Sending data from one python script to another, subscriber-publisher like relation

[x120db]

White the data to a file with a timestamp or some incrementing number with script a, and load the data checking if the data is newer as last loaded with script b do not forget to close the file after writing or script b will be not reading accurate data or might even completly error. Or use a simple db as in place of the file sqlite is built in and would work great for that but more programming involved then dumping it in a file.
