在用 pyecharts 练手的时候，尝试用下表中的数据构造一份折线堆叠图year_line = Line().add_xaxis(summary.columns.to_list())# year_line = Line().add_xaxis([1,2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12,13])for i in range(4): year_line.add_yaxis(str(i+2012), stack='

按网上搜到的结果调用scipy.stats包计算参数已知的置信区间from scipy import stats as sstconf_int = sst.norm.interval(0.95, loc=82, scale=20)# conf_int = sst.norm.cdf(1.96)conf_int输出结果如下：(42.80072030919892, 121.19927969...

执行代码，将 Series 转换成 DataFrame 时：s1 = pd.Series(np.random.rand(5),index=['a','s','d','f','g'])print(s1.unstack())报错情况如下：Traceback (most recent call last): File "C:\Users\liuhao\Desktop\资料\python_w...
