“Text interface” (created by Python interpolation string formatting)

Python interpolates string formats to create program text interfaces.

2. Algorithm analysis

This note focuses on explaining “Text Interface“. The sample code borrows the code I typed when answering this question. According to my understanding and preference, some of the “code logic” has been changed: let two players live in the same category, so that they are not so divided. The total scores of the two players are tallied separately, and at the end of the game, the winner is determined. In this way, what I think is a “more reasonable code” is achieved.

Use Python to interpolate string formatting, easily and freely, making print() more cute and attractive.

2.1 Attribute variables

class Game:
    clear = '\033[2J' # Linux clear screen string.
    wait = f"{<!-- -->'(Any key to continue...)':^34}\\
" # Pause prompt string.
    rule = range(100) # Alternative random score.
    topScore = countScoreA = countScoreB = 0 # The highest score and the initial value of the player's total score.

2.2 Parameter collection

The __init__ class magic method collects parameters: name, game name; *player collects two player names into a list.

    def __init__(self, name, *player):
        self.name = name
        self.pA, self.pB = player

2.3 Game Menu

Menu selection error

The advantage of the for loop printing menu lines is that adding a menu does not require adding code. You only need to append the menu display content string to the for traversal sequence. That’s it.

    def menu(self):
        print(f"{<!-- -->self.clear}\\
{<!-- -->'':=^40}\\
\\
{<!-- -- >f' {<!-- -->self.name} ':^38}\\
\\
{<!-- -->'':~^40}\\
" )
        
        for k, i in enumerate(['Game starts', 'Game pauses', 'Game ends']):
            print(f"{<!-- -->f'{<!-- -->k + 1}. {<!-- -->i}':^36}")

        print(f"\\
{<!-- -->'':=^40}\\
")

2.4 Game Game

{<!-- -->f' {<!-- -->self.pA} and {<!-- -->self.pB} start the game':.^ 31}")
        a, b = choices(self.rule, k=2) # Randomly give game scores (0~100).
        self.countScoreA + = a
        self.countScoreB + = b
        score = a if a > b else b
        self.topScore = score if self.topScore < score else self.topScore # Update the highest score of the recorded game.
        print(f"\\
{<!-- -->f' The current highest score in a single round: {<!-- -->self.topScore:>3} ':~^32}\\

2.8 Loop Game

Call the function module according to the menu if branch to complete the menu instructions
Call yourself to implement menu loop.

    def play(self):
        self.menu()
        choice = input(f"{<!-- -->'Please choose:':>12}")

        if choice == '1':
            self.startGame()
        elif choice == '2':
            self.pauseGame()
        elif choice == '3':
            self.exitGame()
            self.showScore()
            exit()
        else:
            print(f"\\
{<!-- -->f' Wrong menu selection!':~^34}\\
")
            input(self.wait)
        
        self.play() # Call yourself to implement the game menu loop.

2.9 Start the game
