A Character Sketch 

Piscine Molitor Patel, known to all as just "Pi", is the narrator and protagonist of the novel. He was named after a swimming pool in Paris, despite the fact that neither his mother nor his father particularly liked swimming. The story is told as a narrative from the perspective of a middle-aged Pi, now married with his own family, and living in Canada. At the time of main events of the story, he is sixteen years old. He recounts the story of his life and his 227-day journey on a lifeboat when his ship sinks in the middle of the Pacific Ocean during a voyage to North America.
Pi is the youngest son of the director of the zoo. he is the expert on the habits of animals and three world religions. Since childhood, Pi felt a tendency to religion, but simultaneously to Hinduism, Christianity and Islam. This caused the other people sincere surprise, bewilderment and hostility. Different aspects of these religiouns  have helped him in his own experience to feel the beauty of the world. He has never forgotten about the prayer - the daily prayer, supporting undamped spark of hope in the heart. He has a very strong character, he never gives up, he fights to the end. He was still optimistic when there was nowhere to wait for help, when every day was another test, when a neighbour and even the weather was against him. But he still continued to fight, it's the thirst for life, when the main threat, the tiger, proved a lifesaver  for whom it was necessary to get food and water, with whom he can talk to, so who became a partner in misfortune.
Also Pi is a vegetarian since birth, he loves animals very much. Pi hs a very extraordinary thinking,  unusual view of the world which has already appeared in his childhood and helped him survive in an extreme situation in the middle of the open ocean in a boat with a wild beast that though he lived most of his life in the zoo, being caught still young, but still has not lost the grafted nature of instincts.
I respect the strength of his character, his will to live. His attitude to the world makes me think about it.
