解决方案

二维数组的KEY中含有html标签

二、Value 'item_total.append' is unsubscriptable

报错信息：item_total.append[item]

-------------------------------

item_total: list

Value 'item_total.append' is unsubscriptablepylint(unsubscriptable-object)

解决方案

item_total.append[item]改为item_total.append(item)

解决方案

对处理的字符串做判断if string is None

四、Unable to add the Win32_PerfRawData_PerfDisk_PhysicalDisk enum

报错信息：[6668:6348:0625/111147.071:ERROR:wmi_refresher.cc(150)] Unable to add the Win32_PerfRawData_PerfDisk_PhysicalDisk enum.

解决方案加大time.sleep(5) 时间到一个合适的值

五、FutureWarning: Using an implicitly registered datetime converter for a matplotlib plotting method. The converter was registered by pandas on import. Future versions of pandas will require you to explicitly register matplotlib converters.

报错信息：FutureWarning: Using an implicitly registered datetime converter for a matplotlib plotting method. The converter was registered by pandas on import. Future versions of pandas will require you to explicitly register matplotlib converters.

To register the converters:

>>> from pandas.plotting import register_matplotlib_converters

>>> register_matplotlib_converters()

warnings.warn(msg, FutureWarning)

解决方案

添加报错信息中的代码from pandas.plotting import register_matplotlib_converters

register_matplotlib_converters()
