如何在我的程序中重置 A 'Score Bank'？ Python

Question

So I'm trying to add in a scoring system with an external module in a really basic game as I just started Python two days ago.

score_history = [0]

a=cur_score()

def var1():
    scoremodule.cur_score()

def initial_score():
    return score[0]

def cur_score():
    return score_history[-1]

def affect_score(delta):
    score_history.append(cur_score() + delta)
    return cur_score()

def reset_score(var1):
    sub=a-a
    print(sub)

Here's what I have so far. I just need a way to reset the score with the reset_score argument. I can't figure out how to assign cur_score a letter or subtract it from its self. Help would be much appreciated.

Answer 1

what do you want reset_score to do? set a = 0?

def reset_score(var1()):
    a=0

Answer 2

You could use a class to define your methods and then have the score history as an attribute of your class? Is this the result you are after?

class Scorer:
    def __init__(self):
        self.score_history = [0]

    def initial_score(self):
        return self.score_history[0]

    def current_score(self):
        return self.score_history[-1]

    def affect_score(self, delta):
        self.score_history.append(self.score_history[-1] + delta)
        return self.current_score()

    def reset_score(self):
        self.score_history = [0]

scoreboard = Scorer()

print(f"Start: {scoreboard.current_score()}")
print(f"add 5: {scoreboard.affect_score(5)}")
print(f"initial: {scoreboard.initial_score()}")
print(f"current: {scoreboard.current_score()}")
scoreboard.reset_score()
print(f"current after reset: {scoreboard.current_score()}")

Output

Start: 0
add 5: 5
initial: 0
current: 5
current after reset: 0
