Implementation of matplotlib function

import numpy as np import matplotlib.pyplot as plt

x = np.linspace(0, 10, 500) y = np.sin(x**2)+np.cos(x)

plt.plot(x, y, label ='Line 1')

plt.plot(x, y - 0.6, label ='Line 2')

w = plt.get_fignums()

plt.text(2, 1.98, "List of existing figure numbers : " + str(w), fontsize = 12)

plt.title('matplotlib.pyplot.get_fignums() function
Example', fontweight ="bold")

plt.show()

`

Output: Example 2:
