plt绘制sin和cos图像失败，无法显示最终结果

Question

绘制sin和cos图像失败
这是我照书上写的代码

import numpy as np
import matplotlib.pyplot as plt  # 绘制图像
x = np.arange(0, 6, 0.1)
y1 = np.sin(x)
y2 = np.cos(x)


plt.plot(x, y1, label="sin")
plt.plot(x, y2, linestyle = "--", lable="cos")
plt.xlabel("x")
plt.ylabel("y")
plt.title('sin & cos')
plt.legend()
plt.show()

这是书上的源代码

# coding: utf-8
import numpy as np
import matplotlib.pyplot as plt

# 生成数据
x = np.arange(0, 6, 0.1) # 以0.1为单位，生成0到6的数据
y1 = np.sin(x)
y2 = np.cos(x)

# 绘制图形
plt.plot(x, y1, label="sin")
plt.plot(x, y2, linestyle = "--", label="cos")
plt.xlabel("x") # x轴的标签
plt.ylabel("y") # y轴的标签
plt.title('sin & cos')
plt.legend()
plt.show()

这是错误提示

进程已结束,退出代码1

谢谢各位的指导

Answer 1

label吧，你写成了lable
