The President of India is elected by an electoral college.

The process of electing the President of India involves the participation of an electoral college, which is responsible for the selection of the country's highest office. The electoral college consists of elected members of both houses of Parliament, as well as the elected members of the Legislative Assemblies of the states and union territories.

Composition of the Electoral College:
The electoral college consists of the following members:
1. Elected members of both houses of Parliament: The Rajya Sabha (Council of States) and the Lok Sabha (House of the People) together form the Parliament. Members of Parliament (MPs) are elected by the citizens of India through a general election.
2. Elected members of the Legislative Assemblies: Each state in India has a Legislative Assembly, which consists of elected representatives. The number of members in each Legislative Assembly varies based on the population of the state. Similarly, union territories also have a Legislative Assembly with elected members.
3. Members of Legislative Councils: In some states, there is a Legislative Council in addition to the Legislative Assembly. However, members of Legislative Councils do not participate in the election of the President.

Process of Election:
1. Nomination of Candidates: Any individual who meets the eligibility criteria for the presidency can be nominated as a candidate. The nomination requires support from at least 50 electors as proposers and 50 electors as seconders. The nomination papers are scrutinized by the Election Commission of India.
2. Voting Process: The election is conducted through a secret ballot. Each member of the electoral college has one vote. The value of each vote is determined by dividing the total population of India by the total number of elected members in the electoral college. This ensures that the votes of each member are weighted based on the population they represent.
3. Counting of Votes: The counting of votes is done by the Election Commission of India. The candidate who secures a majority of the valid votes cast is declared the winner and becomes the President of India.

Conclusion:
The President of India is elected by an electoral college consisting of elected members of both houses of Parliament and the Legislative Assemblies of the states and union territories. This system ensures that the President is elected by a representative body, reflecting the diversity and federal nature of India's democracy.
