#### Libraries
# Standard library
import sys
import logging
import configparser

import traceback
import pdb

# Third-Party Libraries
# If Pandas is a dependency, a good practice is to consider chained assignments as an error :
import numpy as np
import pandas as pd
pd.set_option('mode.chained_assignment', 'raise')
# it should avoid "SettingWithCopyWarning"

### logger config :
# create logger
logger = logging.getLogger('MyScript') # s'affiche après la date
logger.setLevel(logging.DEBUG)
ch = logging.FileHandler("logs.log")
ch.setLevel(logging.DEBUG)
formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')
ch.setFormatter(formatter)
logger.addHandler(ch)

# Usage example :
#logger.debug('debug message')
#logger.info('info message')
#logger.error('error message')
#logger.critical('critical message')

### ini file config :
config = configparser.ConfigParser()
config.read('configuration.ini')

# Usage example :
# >>> config.sections()
# ['bitbucket.org', 'topsecret.server.com']
# >>> 'bitbucket.org' in config
# True
# >>> 'bytebong.com' in config
# False
# >>> config['bitbucket.org']['User']
# 'hg'
# >>> config['DEFAULT']['Compression']
# 'yes'
# >>> topsecret = config['topsecret.server.com']
# >>> topsecret['ForwardX11']
# 'no'
# >>> topsecret['Port']
# '50022'
# >>> for key in config['bitbucket.org']: print(key)
# ...
# user
# compressionlevel
# serveraliveinterval
# compression
# forwardx11
# >>> config['bitbucket.org']['ForwardX11']
# 'yes'
