问题 I am trying to learn pandas and want to load some stocks data. I was following a course which advised me to load pandas.io.data, but this did not work as io.data was depreciated. So I decided to use pandas-datareader instead. But I am struggling to instal it on mac in Anaconda (Jupiter notebook). First time I run import pandas_datareader as pdweb I got ModuleNotFoundError: No module named 'pandas_datareader'. Not surprising as I never used this before so I run pip3 install pandas_datareader

问题 I have two lists of the same length that I can convert into array to play with the numpy.stats.pearsonr method. Now, some of the elements of these lists are nan , and can thus not be used for that method. The best thing to do in my case is to remove those elements, and the corresponding element in the other list. Is there a practical and pythonic way to do it? Example: I have [1 2 nan 4 5 6 ] and [1 nan 3 nan 5 6] and in the end I need [1 5 6 ] [1 5 6 ] (here the number are representative of

问题 I know that I can get the current location of the mouse cursor by executing "xdotool getmouselocation". I would like to detect the current mouse cursor type such as pointer, beam, or hand cursor from bash terminal or python code. Would this be possible? Thank you. June 回答1: You can use xdotool to continuously click where the link would be until the program notices the window title changes. When the window title changes, that means the link has been clicked, and the new page is loading.
