How does the parliament function?? ?

Once elections to the Parliament have taken place, the Parliament needs to perform the following functions:
TO SELECT THE NATIONAL GOVERNMENT:
• The Parliament in India consists of the President, the Rajya Sabha and the Lok Sabha.

THE LOK SABHA
1 For a political party to form the government in Lok Sabha, they must have a majority of elected MPs.
 → Since there are 543 elected (plus 2 nominated) members in Lok Sabha, to have a majority a party should have at least 
half the number i.e. 272 members or more.
2.Coalition government is formed when one political party does not get simple majority. In such a condition, a group of 
different political parties come together to form a government. 
3.The Prime Minister of India is the leader of the ruling party in the Lok Sabha.
4.From the MPs who belong to her party, the Prime Minister selects ministers to work with her to implement decisions.
RAJYA SABHA
1.The Rajya Sabha functions primarily as the representative of the states of India in the Parliament. 
2.The Rajya Sabha can also initiate legislation and a bill is required to pas through the Rajya Sabha in order to become a law.
3.It, therefore, has an important role of reviewing and altering (if alterations are needed) the laws initiated by the Lok Sabha. 
4.The members of the Rajya Sabha are elected by the elected members of the Legislative Assemblies of various states. 
5.There are 233 elected members plus 12 members nominated by the President.
