緊急です！ pythonのプログラムでelse:の部分でエラーが出てしまいます。 分かる方教えていただけると助かります。 import matplotlib.pyplot as plt import numpy as np from scipy import stats import seaborn as sns plt.style.use('seaborn-darkgrid') theta_real = 0.35 trials = [0, 1, 2, 3, 4, 8, 16, 32, 50, 150] data = [0,1, 1, 1, 1, 4, 6, 9, 13, 48] beta_params = [(1, 1), (0.5, 0.5), (20, 20)] dist = stats.beta x = np.linspace(0, 1, 100) for idx, N in enumerate(trials): if idx == 0: plt.subplot(4, 3, 2) else: plt.subplot(4, 3, idx+3) y = data[idx] for (a_prior, b_prior), c in zip(beta_params, ('b', 'r', 'g')): p_theta_given_y = dist.pdf(x, a_prior + y, b_prior + N - y) plt.plot(x, p_theta_given_y, c) plt.fill_between(x, 0, p_theta_given_y, color=c, alpha=0.6) plt.axvline(theta_real, ymax=0.3, color='k') plt.plot(0, 0, label="{:d} experiments¥n{:d} heads".format(N, y), alpha=0) plt.xlim(0,1) plt.ylim(0,12) plt.xlabel(r'$\theta$') plt.legend() plt.gca().axes.get_yaxis().set_visible(False) plt.tight_layout() plt.savefig('img105.png')
