calling ".sql" files in python

[raopatwari]

Hello Python gurus,
I have sql file, in that
I have some commands like set echo on, set feedback on
and drop table, create table and inserts
and pkg scripts followed by "/".
how do I call this script in pyhton, so far my trials, its not working

def get_rules():
   con = pyutils.conn_st()
   cur = con.cursor()
   f = open("run_all_su.sql")
   full_sql = f.read()
   sql_commands = full_sql.split(';')
   #sql_commands = full_sql.replace('\n', '').split(';')[:-1] # this bring just [] which is  empty
   print(sql_commands)
   for sql_command in sql_commands:
       print(sql_command)
       cur.execute(sql_command)

       cur.close()
   con.close()
