This seemed counterintuitive to me so if anyone has insight into how you can set the config for a logger that hasn't been imported yet I'd be curious to find out how this works. Thanks!

In my main file:

import logging
import requests
logger = logging.getLogger(__name__)
logger.setLevel(logging.DEBUG)
logging.getLogger('requests').setLevel(logging.DEBUG)

def main():
  ...

In my plot.py file:

import logging
logging.getLogger('matplotlib').setLevel(logging.WARNING)
import matplotlib.pyplot as plt

def generatePlot():
  ...
