Rows are not getting inserted to mysql using python

I want to insert some records to mySQL database from PostgreSQL(both are remote servers),So i'm using the below script but the case is that the data is not getting inserted into MySQL database.

There is a final count statement which always results zero.May i know what could be the reason?

Also any improvement need to do on this code.

Suggestions please.
