如何在python中填充几条曲线之间的区域？

import matplotlib.pyplot as plt
import numpy as np

x = np.linspace(0, 2 * np.pi, 100)  # x轴的数据范围
y1 = np.sin(x)  # 第一条曲线的数据
y2 = np.cos(x)  # 第二条曲线的数据

plt.plot(x, y1, color='blue', label='Sin(x)')  # 绘制第一条曲线
plt.plot(x, y2, color='red', label='Cos(x)')  # 绘制第二条曲线
plt.fill_between(x, y1, y2, where=(y1 > y2), color='gray', alpha=0.5)  # 填充区域

plt.legend()  # 添加图例
plt.xlabel('X')  # 添加X轴标签
plt.ylabel('Y')  # 添加Y轴标签

plt.show()
