Today’s question: What is missing from this matplotlib code?
Three lines are missing in the code down below.
import numpy as np
import matplotlib.pyplot as plt
# Parameters
num_steps = 1000
# Generate random walk data
x = np.zeros(num_steps)
y = np.zeros(num_steps)
for i in range(1, num_steps):
angle = np.random.uniform(0, 2 * np.pi)
x[i] = x[i-1] + np.cos(angle)
y[i] = y[i-1] + np.sin(angle)
# Plotting the random walk
plt.figure(figsize=(10, 10))
plt.plot(x, y, linestyle='-', marker='o', markersize=2, alpha=0.75)
...
...
...
plt.show()What code should be placed in the dots so the code generates the following output?
