How to adjust 'tick frequency' in Matplotlib for string Y-axis?

To adjust tick frequency for for Y-axis, we can take the following steps −

Set the figure size and adjust the padding between and around the subplots.
Initialize a variable, N, for number of sample data points.
Create x and y data points using numpy.
Plot x and y data points using plot() method.
Initialize a variable freq_y to adjust the frequency of the yticks.
Use yticks() method to set the yticks.
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

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')

freq_y = 3

plt.yticks(np.arange(0, N, freq_y))

plt.show()
