COMP1001 Data Visualization

Program: Data visualization (Python 3)

(1) Prompt the user for a title for data. Output the title.

Ex:

Enter a title for the data: Number of Novels Authored

You entered: Number of Novels Authored

(2) Prompt the user for the headers of two columns of a table. Output the column headers.

Ex:

Enter the column 1 header: Author name

You entered: Author name

Enter the column 2 header: Number of novels

You entered: Number of novels

(3) Prompt the user for data points. Data points must be in this format: string, int. Store the information before the comma into a string variable and the information after the comma into an integer. The user will enter -1 when they have finished entering data points. Output the data points. Store the string components of the data points in a list of strings. Store the integer components of the data points in a list of integers.

Ex:

Enter a data point (-1 to stop input): Jane Austen, 6

Data string: Jane Austen

Data integer: 6

(4) Perform error checking for the data point entries. If any of the following errors occurs, output the appropriate error message and prompt again for a valid data point.

If entry has no comma

Output: Error: No comma in string.

If entry has more than one comma

Output: Error: Too many commas in input.

If entry after the comma is not an integer

Output: Error: Comma not followed by an integer.

Ex:

Enter a data point (-1 to stop input): Ernest Hemingway 9

Error: No comma in string.

Enter a data point (-1 to stop input): Ernest, Hemingway, 9

Error: Too many commas in input.

Enter a data point (-1 to stop input): Ernest Hemingway, nine

Error: Comma not followed by an integer.

Enter a valid data point: Ernest Hemingway, 9

Data string: Ernest Hemingway

Data integer: 9

(5) Output the information in a formatted table. The title is right justified with a minimum field width value of 33. Column 1 has a minimum field width value of 20.

Column 2 has a minimum field width value of 23.

Ex:

Number of Novels Authored

Author name | Number of novels

--------------------------------------------

Jane Austen | 6

Charles Dickens | 20Ernest Hemingway | 9

Jack Kerouac | 22

Ian Flemming | 14

J.K. Rowling | 14

Ex:

Ernest Hemingway *********

Jack Kerouac **********************

F. Scott Fitzgerald ********

Mary Shelley *******

Charlotte Bronte *****

Program: Soccer team roster (Dictionaries) (Python 3)

This program will store roster and rating information for a soccer team. Coaches rate players during tryouts to ensure a balanced team.

(1) Prompt the user to input five pairs of numbers: A player’s jersey number (0 - 99) and the player’s rating (1 - 9). Store the jersey numbers and the ratings in a dictionary. Output the dictionary’s elements with the jersey numbers in ascending order (i.e., output the roster from smallest to largest jersey number). Hint:

Dictionary keys can be stored in a sorted list.

Ex:

Enter player 1's jersey number: 84

Enter player 1's rating: 7

Enter player 2's jersey number: 23

Enter player 2's rating: 4

Enter player 3's jersey number: 4

Enter player 3's rating: 5

Enter player 4's jersey number: 30

Enter player 4's rating: 2

Enter player 5's jersey number: 66

Enter player 5's rating: 9

ROSTER

Jersey number: 4, Rating: 5

Jersey number: 23, Rating: 4

Jersey number 30, Rating: 2

...

(2) Implement a menu of options for a user to modify the roster. Each option is represented by a single character. The program initially outputs the menu, and outputs the menu after a user chooses an option. The program ends when the user chooses the option to Quit. For this step, the other options do nothing.

Ex:

MENU

a - Add player

d - Remove player

u - Update player rating

r - Output players above a rating

o - Output roster

q - Quit

Choose an option:

(3) Implement the “Output roster” menu option.

Ex:

ROSTER

Jersey number: 4, Rating: 5

Jersey number: 23, Rating: 4

Jersey number 30, Rating: 2

...

(4) Implement the “Add player” menu option. Prompt the user for a new player’s jersey number and rating. Append the values to the two vectors.

Ex:

Enter a new player's jersey number: 49

Enter the player's rating: 8

(5) Implement the “Delete player” menu option. Prompt the user for a player’s jersey number. Remove the player from the roster (delete the jersey number and rating).

Ex:

Enter a jersey number: 4

(6) Implement the “Update player rating” menu option. Prompt the user for a player’s jersey number. Prompt again for a new rating for the player, and then change that player’s rating.

Ex:

Enter a jersey number: 23

Enter a new rating for player: 6

(7) Implement the “Output players above a rating” menu option. Prompt the user for a rating. Print the jersey number and rating for all players with ratings above the entered value.

Ex:

Enter a rating: 5

ABOVE 5

Jersey number: 66, Rating: 9

Jersey number: 84, Rating: 7
