我如何才能得到一个事件的出现次数超过了该事件自身的平均值？

def get_event_counts(events):
    event_counts = {}  # 用于记录事件的出现次数
    total_count = 0  # 用于计算事件的总数

    # 统计事件的出现次数
    for event in events:
        if event in event_counts:
            event_counts[event] += 1
        else:
            event_counts[event] = 1
        total_count += 1

    # 计算事件的平均值
    average_count = total_count / len(event_counts)

    # 比较事件的出现次数和平均值，并输出结果
    result = []
    for event, count in event_counts.items():
        if count > average_count:
            result.append((event, count))

    return result

# 示例用法
events = ['A', 'B', 'A', 'C', 'B', 'A', 'D', 'E', 'B', 'C']
result = get_event_counts(events)
print(result)
