遍历Python矩阵中特定列中的行

Question

我想对此图进行动画处理，并尝试遍历第一列中的行以设置x0值，第二列中的行设置y0值。我该如何正确地将x0的值设置为y0以使其正确动画？

完整代码如下：

FFMpegWriter = manimation.writers['ffmpeg']
metadata = dict(title='Movie Test', artist='Matplotlib',
        comment='Movie support!')
writer = FFMpegWriter(fps=15, metadata=metadata)

if __name__ == "__main__":

    import glob
    filenames = glob.glob(r"C:\Users\Admin\Desktop\hiddenforprivacy)
    

    for fn in filenames[8:9]:
        tups = bball.stats_basketball.read_tuples(fn)
       
        
        positions = bball.stats_basketball.get_positions(tups)
        goals = bball.stats_basketball.get_goals(tups)
        fig = plt.figure()



with writer.saving(fig, "writer_test.mp4", 100):
    for x in range(100):
        for i in range(1, 6):
            p_o = positions[i]
            x0, y0 = p_o[0,0], p_o[0,1]
            
            #where i started and am now stuck
            #for row in p_o[:,0]:
                

            if i == 1:
                
                l, = plt.plot([],[], color='steelblue', linewidth=5)    
                l.set_data(x0,y0)

                writer.grab_frame()
