Utilize the sаved csv frоm the previоus titаnic chаllenge and titanic2.py as the starting pоint. Write a script to calculate the survival rate of "young adult" passengers (ages 18–23 inclusive) across the three different passenger classes (1, 2, and 3). Load the CSV into a DataFrame. (10 pts) Filter the data for passengers between ages 18 and 23. (10 pts) Group by Pclass and calculate the mean of the Survived column. (20 pts) Display the result as a percentage (e.g., 0.35 becomes 35%). (10 pts) titanic2.py should be used as a start, and the uploaded file should have the same name.
