India has a bicameral legislature. Our Constitution provides that Parliament shall consist of:

1. The President 
2. The Council of States (Rajya Sabha) and 
3. The House of the People (Lok Sabha)

Though the President of India is not a member of either House of Parliament and does not sit in the Parliament to attend its meetings, he/she is an integral part of the Parliament.
