我希望我的代码检查多个条件，并选择已经满足的条件并执行它。不幸的是，我的代码没有返回任何东西。

Question

corr是相关系数，意思是I有3个相关值，std_mev是标准差值，也就是3个标准差值。我希望我的代码检查下面代码中的条件是否满足，如果满足了，它应该执行为true的语句，并计算induc值，如代码所示。不幸的是，没有错误，甚至没有执行来产生工业值，请协助，我有一张附图来显示这一点。

。守则如下：

    corr1,_ = pearsonr(list_losses, list_mev1)
    print('Pearsons correlation[loss and MEV1]: %.4f' % corr1)

    corr2,_ = pearsonr(list_losses, list_mev2)
    print('Pearsons correlation[loss and MEV2]: %.4f' % corr2)

    corr3,_ = pearsonr(list_losses, list_mev3)
    print('Pearsons correlation[loss and MEV3]: %.4f' % corr3)

    ### calculating standard deviation
    std_mev1 = statistics.stdev(std_mev1_list)
    std_mev2 = statistics.stdev(std_mev2_list)
    std_mev3 = statistics.stdev(std_mev3_list)

    print("Std MEV 1 = ",std_mev1)
    print("Std MEV 1 = ",std_mev2)
    print("Std MEV 1 = ",std_mev3)

Answer 1

虽然这不是一个答案(我认为@abdullatif给了您一个答案)，但我认为这是对您应该考虑的代码的简化。当然，检查它以确保它能做你想做的事情，但我认为它做到了。

corr1_multiplier = (1 + std_mev1) if corr1 >= 0.5 else 1.0
corr2_multiplier = (1 + std_mev2) if corr2 >= 0.5 else 1.0
corr3_multiplier = (1 + std_mev3) if corr3 >= 0.5 else 1.0
corr_multiplier = corr1_multiplier * corr2_multiplier * corr3_multiplier

induc_cur_ls = cur_ls * corr_multiplier
induc_on2_ls = on2_ls * corr_multiplier
induc_tt2_ls = tt2_ls * corr_multiplier
induc_sx2_ls = sx2_ls * corr_multiplier
induc_nn2_ls = nn2_ls * corr_multiplier

Answer 2

一切似乎都是正确的，但最后几行中的打印在未执行的lines条件内。这就是为什么你的代码不打印任何东西。试着将它们缩回原处，使其处于这样的状态之外：

    else:
        induc_cur_ls = cur_ls
        induc_on2_ls = on2_ls
        induc_tt2_ls = tt2_ls
        induc_sx2_ls = sx2_ls
        induc_nn2_ls = nn2_ls

    print(induc_cur_ls)
    print(induc_on2_ls)
    print(induc_tt2_ls)
    print(induc_sx2_ls)
    print(induc_nn2_ls)
