Using Jupyter
Colorized Logging
Setup awesome colorized logging by adding the following code to the root folder of your project. Call it something like colorized_logging.py (reference https://gist.github.com/joshbode/58fac7ababc700f51e2a9ecdebe563ad).
python
import sys
import logging
from typing import Optional, Dict
from colorama import Fore, Back, Style
class ColoredFormatter(logging.Formatter):
"""Colored log formatter."""
def __init__(self, *args, colors: Optional[Dict[str, str]]=None, **kwargs) -> None:
"""Initialize the formatter with specified format strings."""
super().__init__(*args, **kwargs)
self.colors = colors if colors else {}
def format(self, record) -> str:
"""Format the specified record as text."""
record.color = self.colors.get(record.levelname, '')
record.reset = Style.RESET_ALL
return super().format(record)
formatter = ColoredFormatter(
'{asctime} |{color} {levelname:8} {reset}| {name} | {message}',
style='{', datefmt='%Y-%m-%d %H:%M:%S',
colors={
'DEBUG': Fore.CYAN,
'INFO': Fore.GREEN,
'WARNING': Fore.YELLOW,
'ERROR': Fore.RED,
'CRITICAL': Fore.RED + Back.WHITE + Style.BRIGHT,
}
)
handler = logging.StreamHandler(sys.stdout)
handler.setFormatter(formatter)
logger = logging.getLogger()
logger.handlers[:] = []
logger.addHandler(handler)
logger.setLevel(logging.DEBUG)
import sys
import logging
from typing import Optional, Dict
from colorama import Fore, Back, Style
class ColoredFormatter(logging.Formatter):
"""Colored log formatter."""
def __init__(self, *args, colors: Optional[Dict[str, str]]=None, **kwargs) -> None:
"""Initialize the formatter with specified format strings."""
super().__init__(*args, **kwargs)
self.colors = colors if colors else {}
def format(self, record) -> str:

record.color = self.colors.get(record.levelname, '')
record.reset = Style.RESET_ALL
return super().format(record)
formatter = ColoredFormatter(
'{asctime} |{color} {levelname:8} {reset}| {name} | {message}',
style='{', datefmt='%Y-%m-%d %H:%M:%S',
colors={
'DEBUG': Fore.CYAN,
'INFO': Fore.GREEN,
'WARNING': Fore.YELLOW,
'ERROR': Fore.RED,
'CRITICAL': Fore.RED + Back.WHITE + Style.BRIGHT,
}
)
handler = logging.StreamHandler(sys.stdout)
handler.setFormatter(formatter)
logger = logging.getLogger()
logger.handlers[:] = []
logger.addHandler(handler)
logger.setLevel(logging.DEBUG)
Next, in your Jupyter notebook, import this file, along with the logging
library.
python
import color_logging
from logging import \
info as loginfo, \
debug as logdebug, \
warning as logwarn, \
error as logerror
