代写两个基础的Python程序，考察格式化输出以及逻辑流程控制。

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 AuthoredYou 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 nameYou entered: Author nameEnter the column 2 header: Number of novelsYou 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, 6Data string: Jane AustenData 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 9Error: No comma in string.Enter a data point (-1 to stop input): Ernest, Hemingway, 9Error: Too many commas in input.Enter a data point (-1 to stop input): Ernest Hemingway, nineError: Comma not followed by an integer.Enter a valid data point: Ernest Hemingway, 9Data string: Ernest HemingwayData 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 AuthoredAuthor name         |       Number of novels--------------------------------------------Jane Austen         |                      6Charles Dickens     |                     20Ernest Hemingway    |                      9Jack Kerouac        |                     22F. Scott Fitzgerald |                      8Mary Shelley        |                      7Charlotte Bronte    |                      5Mark Twain          |                     11Agatha Christie     |                     73Ian Flemming        |                     14J.K. Rowling        |                     14Stephen King        |                     54Oscar Wilde         |                      1

(6) Output the information as a formatted histogram. Each name is right justified with a minimum field width value of 20.
Ex:

        Jane Austen ******Charles Dickens ********************Ernest Hemingway *********Jack Kerouac **********************F. Scott Fitzgerald ********Mary Shelley *******Charlotte Bronte *****Mark Twain ***********Agatha Christie *************************************************************************Ian Flemming **************J.K. Rowling **************Stephen King ******************************************************Oscar Wilde *

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 players jersey number (0 - 99) and the players rating (1 - 9). Store the jersey numbers and the ratings in a dictionary. Output the dictionarys 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: 84Enter player 1's rating: 7Enter player 2's jersey number: 23Enter player 2's rating: 4Enter player 3's jersey number: 4Enter player 3's rating: 5Enter player 4's jersey number: 30Enter player 4's rating: 2Enter player 5's jersey number: 66Enter player 5's rating: 9ROSTERJersey number: 4, Rating: 5Jersey number: 23, Rating: 4Jersey 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:

MENUa - Add playerd - Remove playeru - Update player ratingr - Output players above a ratingo - Output rosterq - QuitChoose an option:

(3) Implement the Output roster menu option.
Ex:

ROSTERJersey number: 4, Rating: 5Jersey number: 23, Rating: 4Jersey number 30, Rating: 2...

(4) Implement the Add player menu option. Prompt the user for a new players jersey number and rating. Append the values to the two vectors.
Ex:

Enter a new player's jersey number: 49Enter the player's rating: 8

(5) Implement the Delete player menu option. Prompt the user for a players 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 players jersey number. Prompt again for a new rating for the player, and then change that players rating.
Ex:

Enter a jersey number: 23Enter 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: 5ABOVE 5Jersey number: 66, Rating: 9Jersey number: 84, Rating: 7...
