8.19 LAB*: Program: Soccer team roster (Dictionaries)

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. (3 pts)

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. (2 pts)

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. (1 pt)

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. (1 pt)

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). (1 pt)

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. (1 pt)

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. (2 pts)

Ex:

Enter a rating:
5

ABOVE 5
Jersey number: 66, Rating: 9
Jersey number: 84, Rating: 7

Is there anyway I could get an example to set this python function set up? any help would be amazing.

basetonum (S, B) --- int:

1. This function accepts as input a string S and a base B (int) where S represents a number in base B where B is between 2 and 10 inclusive. It should then return an integer in base 10 representing the same number as S. It should output 0 when S is the empty string. This function is the inverse of the previous function numtobase().

2. Parameters: S (string), B (int)

3. Returns : integer

4. The function displays nothing.

5. Steps to convert any base system to decimal:

   Step 1 − Determine the column (positional) value of each digit (this depends on the position of the digit and the base of the number system).
   Step 2 − Multiply the obtained column values (in Step 1) by the digits in the corresponding columns.

   Step 3 − Sum the products calculated in Step 2. The total is the equivalent value in decimal.

   Example with S = '11101' and B = 2 Binary Number − 11101 Calculating Decimal Equivalent −

   Nb43210 Step 1 11101 (1×2) + (1×2) + (1×2) + (0×2) + (1×2)

   Step2 11101 16+8+4+0+1 Step 3 11101 29

Binary Number − 11101 = Decimal Number – 29

Again, the key is to ask yourself... what has to change in order to output base B instead of base 2?

In [1]: basetonum('11101', 2) Out[1]: 29

In [2]: basetonum('', 4) Out[2]: 0

A mass of 1 slug, when attached to a spring, stretches it 2 feet. It is released from a point 1 foot above the equilibrium position with a downward velocity of 2 ft/s.

1) Find the equation of motion if the surrounding medium offers a damping force that is numerically equal to 4 times the instantaneous velocity.

2) Classify the motion as underdamped, overdamped, or critically damped.
