python - 変数が別の変数と等しいことを Python が検出しない

Question

家族で卓球のスコアを記録するプログラムを作っています。スコア制限に達すると、ゲームが終了し、誰が勝ったかが表示されます。これはあるプレーヤーでは機能しますが、他のプレーヤーでは機能しません。その理由はわかりません。P2 のスコアが 11 に達すると、P2 が勝利して再開すると表示されますが、P1 のスコアが 11 に達すると、そのまま続行されます。私はこれが初めてであることを覚えておいてください。コードは次のとおりです。

import sys

def defaults():
    global p1sc
    global p2sc

    sclimit = 11
