好的,我可以帮您解决这个问题。
首先,让我们来看一下表 9-8 中的数据:
| 月份 | 食品 | 衣着 | 居住 | 交通 | 通讯 | 娱乐 | 医疗 | 其他 |
| ---- | ---- | ---- | ---- | ---- | ---- | ---- | ---- | ---- |
| 1 | 2000 | 1500 | 2500 | 1000 | 500 | 1000 | 500 | 500 |
| 2 | 1800 | 1000 | 2500 | 1000 | 500 | 1200 | 500 | 300 |
| 3 | 2200 | 1200 | 2500 | 800 | 500 | 800 | 700 | 300 |
| 4 | 2400 | 1500 | 2500 | 1200 | 500 | 500 | 800 | 400 |
| 5 | 2600 | 1200 | 2500 | 1000 | 500 | 700 | 1000 | 500 |
| 6 | 2800 | 1000 | 2500 | 800 | 500 | 900 | 600 | 400 |
| 7 | 3000 | 1500 | 2500 | 1200 | 500 | 1000 | 500 | 500 |
| 8 | 3200 | 1200 | 2500 | 1000 | 500 | 1200 | 800 | 700 |
| 9 | 3400 | 1000 | 2500 | 800 | 500 | 800 | 500 | 400 |
| 10 | 3600 | 1500 | 2500 | 1000 | 500 | 500 | 500 | 300 |
| 11 | 3800 | 1200 | 2500 | 1200 | 500 | 900 | 800 | 500 |
| 12 | 4000 | 1000 | 2500 | 800 | 500 | 1200 | 600 | 400 |
接下来,我们需要根据用户输入的月份,提取对应的数据。以下是一个示例代码,可以实现这个功能:
```python
import matplotlib.pyplot as plt
# 定义数据
data = [
{"month": 1, "food": 2000, "clothing": 1500, "housing": 2500, "transportation": 1000, "communication": 500, "entertainment": 1000, "medical": 500, "other": 500},
{"month": 2, "food": 1800, "clothing": 1000, "housing": 2500, "transportation": 1000, "communication": 500, "entertainment": 1200, "medical": 500, "other": 300},
{"month": 3, "food": 2200, "clothing": 1200, "housing": 2500, "transportation": 800, "communication": 500, "entertainment": 800, "medical": 700, "other": 300},
{"month": 4, "food": 2400, "clothing": 1500, "housing": 2500, "transportation": 1200, "communication": 500, "entertainment": 500, "medical": 800, "other": 400},
{"month": 5, "food": 2600, "clothing": 1200, "housing": 2500, "transportation": 1000, "communication": 500, "entertainment": 700, "medical": 1000, "other": 500},
{"month": 6, "food": 2800, "clothing": 1000, "housing": 2500, "transportation": 800, "communication": 500, "entertainment": 900, "medical": 600, "other": 400},
{"month": 7, "food": 3000, "clothing": 1500, "housing": 2500, "transportation": 1200, "communication": 500, "entertainment": 1000, "medical": 500, "other": 500},
{"month": 8, "food": 3200, "clothing": 1200, "housing": 2500, "transportation": 1000, "communication": 500, "entertainment": 1200, "medical": 800, "other": 700},
{"month": 9, "food": 3400, "clothing": 1000, "housing": 2500, "transportation": 800, "communication": 500, "entertainment": 800, "medical": 500, "other": 400},
{"month": 10, "food": 3600, "clothing": 1500, "housing": 2500, "transportation": 1000, "communication": 500, "entertainment": 500, "medical": 500, "other": 300},
{"month": 11, "food": 3800, "clothing": 1200, "housing": 2500, "transportation": 1200, "communication": 500, "entertainment": 900, "medical": 800, "other": 500},
{"month": 12, "food": 4000, "clothing": 1000, "housing": 2500, "transportation": 800, "communication": 500, "entertainment": 1200, "medical": 600, "other": 400},
]
# 获取用户输入的月份
month = int(input("请输入月份:"))
# 查找对应月份的数据
month_data = None
for d in data:
if d["month"] == month:
month_data = d
break
# 如果找到了对应月份的数据,就绘制饼图
if month_data:
# 提取数据
labels = ["食品", "衣着", "居住", "交通", "通讯", "娱乐", "医疗", "其他"]
values = [month_data["food"], month_data["clothing"], month_data["housing"], month_data["transportation"], month_data["communication"], month_data["entertainment"], month_data["medical"], month_data["other"]]
# 绘制饼图
fig, ax = plt.subplots()
ax.pie(values, labels=labels, autopct='%1.1f%%')
ax.axis('equal')
ax.set_title(f"{month}月份消费饼图")
plt.show()
else:
print("输入的月份无效。")
```
您可以运行这个代码,并输入您想要查看的月份,程序会自动绘制对应的饼图。希望这能够帮到您。
