Outline

  1. Use pandas library to process the IMDb database.
  • Remove the columns which are not required. This has been done by removing the columns which are required from the list of all column headings. We are keeping release_year, cast, director, keywords and tagline as 5 features of a movie.
  • All the rows having at least one missing value are removed using dropna function from Pandas.
  • We only keep the rows which have english alpha numerical movie title.
  • We remove all the rows which have , in the movie title or any of the 5 features. This has been done to make sure that the commas are present only to separate the data across columns in CSV file.
  • We only keep movies with titles less than or equal to 20 and tagline length less than or equal to 30.
  • Save the final database to a CSV file using to_csv function from Pandas.

  1. Read the dataset from the CSV file and store it in dictionary format: movie_title:[year,list of keywords, tagline, director, list of cast]- read_from_csv

  2. Get a random movie from the list of movies and get all the information (5 features) for that movie - get_movie_info

  3. From the 5 movie features, select any 3 features. If the features have list of keywords and/or list of cast, randomly select one from the list - select_hints

  4. Read the hangman template - get_canvas

  5. Get the points where each blank rectanglular box will be drawn depending on the maximum width and height among all the characters present in the movie name - get_char_coords

  6. Draw the blank rectangular boxes - draw_blank_rects

  7. While the number of incorrect attempts is less than 6 and the game hasn't been won or lost yet:

  • Take character input from user
  • If the character is invalid (not an alphabet), display INVALID CHARACTER
  • Else if the character has already been entered, display ALREADY USED
  • Else if the character is NOT present in movie title, display WRONG, increment number of incorrect attempts, display another body part in Hangman, and display the character in Letters used
  • Else, display CORRECT, display the letters in the blank rectangles and display the character in Letters used
  • If all characters in movie have been guessed, break the loop and display YOU WON
  • If number of incorrect attempts are equal to or more than 6, break the loop and display YOU LOST

  1. Reveal the movie name at the end of the game.

  2. Wait for the user to press a key and quit.

The entire game will run on full screen by default.
