调用日志输出错误：TypeError: 'int' object is not callable

 logging.INFO('%s'%frames[0:3])

　　错误信息：

Traceback (most recent call last):
  File "Visualization_bubble_sort.py", line 81, in <module>
    plt,_=draw_chart(od)
  File "Visualization_bubble_sort.py", line 27, in draw_chart
    logging.INFO('%s'%frames[0:3])
TypeError: 'int' object is not callable

　　原因，应该把INFO改为小写

 logging.info('%s'%frames[0:3])
