在PyCharm中控制台输出日志分层级分颜色显示的方法
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
以上这篇在PyCharm中控制台输出日志分层级分颜色显示的方法就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持中文源码网。
