I'm not sure you need to use executemany here when you're only executing a single statement. You could use simply:

cur.execute("UPDATE SEN_Table SET SenNumber = " + senNumStr + " WHERE FormName='" + nameGroup + "'")

It would be better to use a parameterised query rather than a formatted string though, to avoid SQL injection vulnerabilities:

cur.execute("UPDATE SEN_Table SET SenNumber = ? WHERE FormName = ?", (senNumStr, nameGroup))
