So to insert multiple values to my psql table I use the following code:

sql_query = "INSERT INTO %s(%s) VALUES(%%s,%%s,%%s)" % (table_name, my_columns)
cursor = connection.cursor()
cursor.executemany(sql_query, tupled_data)

where tupled_data is a list of tuples where each element in each tuple is a new entry for the corresponding column.
I want to know if this is a safe way to do this kind of stuff ? Is it secured from sql injections ?
I found some possible answers here but it only states that it is safe for the cursor.execute() function and I want to know if it is the same for executemany()
