It seems like you’re trying to plot the time taken to compute the factorial of each number from 1 to 150. However, there are a few issues with your code:

  1. You’re not storing the time taken for each factorial computation. Instead, you’re overwriting dt in each iteration.
  2. The plot function is called inside the loop, which is not necessary and can cause issues.
  3. The plot function is not defined in your code. You might want to use a library like matplotlib.pyplot for plotting.
import numpy as np
import time
import math
import matplotlib.pyplot as plt

n = np.arange(1, 151)
dt = np.zeros_like(n, dtype=float)

for i in range(150):
    start_time = time.time()
    math.factorial(i+1) # replace np.math.factorial with math.factorial
    dt[i] = (time.time() - start_time)

plt.plot(n, dt)
plt.ylabel('Time taken (s)')
plt.title('Time taken to compute factorial')
