represent parenthetical grouping e.g., python allows us use indentation instead although this might not work too great if we had multiple levels involving lots of tiny sub-sections as there just wouldn't be enough visual clarity. what are the benefits of using parentheses in programming languages...

Python 中的 numpy.mean() numpy.mean(arr, axis = None):计算给定数据(数组元素)沿指定轴的算术平均值(平均值)。 参数:arr:【array _ like】输入数组。轴:【int 或 int 的元组】轴,我们要沿着该轴计算算术平均值。否则,将考虑将 arr 展平(在所有 轴上工作)。axis = 0 表示沿列工作,axis = 1 表示...
• Test your Python program for different variations of your strategies, e.g., select “1/n” portfolio at the beginning of period 1 and hold it till the end of period 12 (as if the re- balancing strategy required large transaction costs). Discuss if you are able to achieve better re...
