How to add black border to matplotlib 2.0 'ax' object In Python 3?

To add black border to matplotlib 2.0 'ax' object in Python, we can take the following steps −

Set the figure size and adjust the padding between and around the subplots.
Set axes edgecolor to black.
Set axes linewidth to 2.50.
Initialize a variable, N, to get the number of sample data.
Create x and y data points using numpy.
Plot x and y data points using plot() method.
To display the figure, use show() method.

Example

import matplotlib.pyplot as plt
import numpy as np

plt.rcParams["figure.figsize"] = [7.50, 3.50]
plt.rcParams["figure.autolayout"] = True
plt.rcParams["axes.edgecolor"] = "black"
plt.rcParams["axes.linewidth"] = 2.50

N = 10
x = np.random.randint(low=0, high=N, size=N)
y = np.random.randint(low=0, high=N, size=N)

plt.plot(x, y, color='red')

plt.show()
