### pycharm如何不同等级日志显示不同颜色 ###

在PyCharm中，可以通过修改日志记录器的日志级别来改变日志的显示颜色。以下是一些常见的日志级别及其对应的颜色：

*  DEBUG：灰色
 *  INFO：绿色
 *  WARNING：黄色
 *  ERROR：红色
 *  CRITICAL：红色

要修改日志级别，请按照以下步骤操作：

1.  打开PyCharm并导航到"File" -> “Settings”。
2.  在设置窗口中，选择"Editor" -> “Color Scheme”。
3.  在"Color Scheme"选项卡中，选择"Console Colors"。
4.  在"Console Colors"选项卡中，找到"Log Console"部分。
5.  在"Log Console"部分，可以看到不同的日志级别和它们的颜色设置。
6.  单击要修改的日志级别，并选择所需的颜色。
7.  单击"Apply"或"OK"按钮以保存更改。
