你应该使用 global 关键字,以引用在外部范围中定义的对象。

您的代码应该如下所示:

def playerGainSoldiers():
    global playerExtraSoldier
    playerExtraSoldiers+=100*len(playerCountries)
    if(ownsNorth==1):
        playerExtraSoldiers+=250
    if(ownsCentral==1):
        playerExtraSoldiers+=600
    if(ownsSouth==1):
        playerExtraSoldiers+=350
