今天小编就为大家分享一篇在PyCharm中控制台输出日志分层级分颜色显示的方法,具有很好的参考价值,希望对大家有所帮助。一起跟随小编过来看看吧

1、把下面代码复制到一个.py文件中

#!/usr/bin/env python
# encoding: utf-8
import logging

# now we patch Python code to add color support to logging.StreamHandler
def add_coloring_to_emit_windows(fn):
  # add methods we need to the class
  def _out_handle(self):
    import ctypes
    return ctypes.windll.kernel32.GetStdHandle(self.STD_OUTPUT_HANDLE)
  out_handle = property(_out_handle)
  def _set_color(self, code):
    import ctypes
    # Constants from the Windows API
    self.STD_OUTPUT_HANDLE = -11
    hdl = ctypes.windll.kernel32.GetStdHandle(self.STD_OUTPUT_HANDLE)
    ctypes.windll.kernel32.SetConsoleTextAttribute(hdl, code)
  setattr(logging.StreamHandler, '_set_color', _set_color)
  def new(*args):
    FOREGROUND_BLUE = 0x0001 # text color contains blue.
    FOREGROUND_GREEN = 0x0002 # text color contains green.
    FOREGROUND_RED = 0x0004 # text color contains red.
    FOREGROUND_INTENSITY = 0x0008 # text color is intensified.
    FOREGROUND_WHITE = FOREGROUND_BLUE | FOREGROUND_GREEN | FOREGROUND_RED
    # winbase.h
    STD_INPUT_HANDLE = -10
    STD_OUTPUT_HANDLE = -11
    STD_ERROR_HANDLE = -12
    # wincon.h
    FOREGROUND_BLACK = 0x0000
    FOREGROUND_BLUE = 0x0001
    FOREGROUND_GREEN = 0x0002
    FOREGROUND_CYAN = 0x0003
    FOREGROUND_RED = 0x0004
    FOREGROUND_MAGENTA = 0x0005
    FOREGROUND_YELLOW = 0x0006
    FOREGROUND_GREY = 0x0007
    FOREGROUND_INTENSITY = 0x0008 # foreground color is intensified.
    BACKGROUND_BLACK = 0x0000
    BACKGROUND_BLUE = 0x0010
    BACKGROUND_GREEN = 0x0020
    BACKGROUND_CYAN = 0x0030
    BACKGROUND_RED = 0x0040
    BACKGROUND_MAGENTA = 0x0050
    BACKGROUND_YELLOW = 0x0060
    BACKGROUND_GREY = 0x0070
    BACKGROUND_INTENSITY = 0x0080 # background color is intensified.
    levelno = args[1].levelno
    if (levelno >= 50):
      color = BACKGROUND_YELLOW | FOREGROUND_RED | FOREGROUND_INTENSITY | BACKGROUND_INTENSITY
    elif (levelno >= 40):
      color = FOREGROUND_RED | FOREGROUND_INTENSITY
    elif (levelno >= 30):
      color = FOREGROUND_YELLOW | FOREGROUND_INTENSITY
    elif (levelno >= 20):
      color = FOREGROUND_GREEN
    elif (levelno >= 10):
      color = FOREGROUND_MAGENTA
    else:
      color = FOREGROUND_WHITE
    args[0]._set_color(color)
    ret = fn(*args)
    args[0]._set_color(FOREGROUND_WHITE)
    # print "after"
    return ret
  return new

def add_coloring_to_emit_ansi(fn):
  # add methods we need to the class
  def new(*args):
    levelno = args[1].levelno
    if (levelno >= 50):
      color = '\x1b[31m' # red
    elif (levelno >= 40):
      color = '\x1b[31m' # red
    elif (levelno >= 30):
      color = '\x1b[33m' # yellow
    elif (levelno >= 20):
      color = '\x1b[32m' # green
    elif (levelno >= 10):
      color = '\x1b[35m' # pink
    else:
      color = '\x1b[0m' # normal
    try:
      args[1].msg = color + args[1].msg + '\x1b[0m' # normal
    except Exception as e:
      pass
    # print "after"
    return fn(*args)
  return new

import platform
if platform.system() == 'Windows':
  # Windows does not support ANSI escapes and we are using API calls to set the console color
  logging.StreamHandler.emit = add_coloring_to_emit_windows(logging.StreamHandler.emit)
else:
  # all non-Windows platforms are supporting ANSI escapes so we use them
  logging.StreamHandler.emit = add_coloring_to_emit_ansi(logging.StreamHandler.emit)
  # log = logging.getLogger()
  # log.addFilter(log_filter())
  # //hdlr = logging.StreamHandler()
  # //hdlr.setFormatter(formatter())

2、将文件放到项目的utils包中(或者项目其他路径)

3、在配置文件中导入这个py文件

比如在Django的setting.py文件中配置日志信息时,可以先导入这个文件

之后运行代码,控制台会根据日志等级显示不同的颜色

4、pycharm版本最好是17版本以上的
