Question

Need a program in python.

Asterix and Obelix want to store and process information about movies they are interested in. So, you have been commissioned to write a program in Python to automate this. Since they are not very computer literate, your program must be easy for them to use. They want to store the information in a comma separated text file. Using this they would need to generate a report – see all items AND show a bar chart based on number of movie of each genre.

Your task Write a menu based program to allow user to

0. Exit program

1. Enter details

2. Reports

Task details:

0. Exit

When user enters 0, exit the program.

1. Enter details

When 1 is selected; allow user to enter the following. Perform specified validation

Validation Item Movie name Must be at least 5 characters long Can only be: Romance, Rom-com, Action, War, Spy, Si-fi, Horror, Genre Historic, Fantasy or Animated. HINT: use a numeric menu to select from. Numeric, 1 to 10 Rating When above three valid values have been entered, write all three into a text file separated by commas. For example: Mulan, Animated, 9 Allow user to enter more than 1 item at a time. Use 'y as sentinel value to repeat the loop of data entry 2. Reports When user enters 2, show another menu: 0. Return to previous menu 1. List all movies and draw bar graph (using turtle) O. Return to previous menu When user enters zero on this menu, return to previous menu. List all movies and draw bar chart 1. When user enters 1, list all movies stored in the text file. Display information in a formatted manner. For example: Rating Genre Name animated Mulan sound of music musical amelie rom-com wreck it ralph animated 7 6 fantasy Harry Potter and Goblet of fire 8 Warhorse war Tangled animated 6 animated Madagascar 1 1 Bar chart: Draw a bar chart based on number of movies of each genre. [Refer to: ATurtle BarChart.html on 'How to think like computer scientist' website] Sample comedy musical Fomance om-com action horror historicfantasy animated spy si-fi Technical requirements: Following components must be present in your application: 1. Functions 2. Validation 3. Read and write text file
