    increasing_money = 10   # 每周递增的金额
    end_week = 52           # 总共存52周
    saving_money = 0        # 目前账户有多少金额

    money_list = []
    while i <= end_week :
        saving_money = math.fsum(money_list)         #现在账户有多少元
        money_list.append(money_everyweek)
        print(&#39;第{}周,存入{}元,目前账户有{}元&#39;.format(i, money_everyweek, saving_money))
        money_everyweek += increasing_money     #每周存入的金额数为上一周的加上递增金额
        i += 1                                  # 递增的周数
