我正在尝试模拟硬币抛掷和利润并在 matplotlib 中绘制图表：
from random import choice
import matplotlib.pyplot as plt
import time
start_time = time.time()
num_of_graphs = 2000
tries = 2000
coins = [150, -100]
last_loss = 0
for a in range(num_of_graphs):
profit = 0
line = []
for i in range(tries):
profit = profit + choice(coins)
if (profit < 0 and last_loss < i):
last_loss = i
line.append(profit)
plt.plot(line)
plt.show()
print("--- %s seconds ---" % (time.time() - start_time))
print("No losses after " + str(last_loss) + " iterations")
最终结果是 …
