result = Counter(sentiment_list)
total = len(sentiment_list)
print("宜宾旅游口碑情感统计结果：")
for label, num in result.items():
print(f"{label}：{num} 条，占比 {num/total:.2%}")

绘制情感分布饼图

plt.figure(figsize=(8,6))
plt.pie(result.values(), labels=result.keys(), autopct="%1.2f%%", shadow=True, startangle=90)
plt.title("宜宾蜀南竹海、李庄古镇、五粮液景区游客情感分布")
plt.axis("equal")
