How do I mark the vertices and add the x and y values to the coordinates?

Question

If I plot the graph with matplotlib, how do I mark the vertices and add the x and y values to the coordinates? My code is as follows. Thank you.

import numpy as np
import matplotlib.pyplot as plt
def f(x):[![enter image description here][1]][1]
     return x ** 2
If __name__ == '__main__':
     x = np.arange(-2, 2, 0.1)
     y = f(x)
     plt.plot(x, y, label='f(x)')
     plt.legend()
     plt.show()

Answer 1

Do you mean x and y labels?

You can do:

plt.xlabel('xlabel') plt.ylabel('ylabel')

To label that specific point, you can try:

plt.annotate('label', xy=(x, y) )
