1.3 Deploy modules and logging
Python is an extensible scripting platform that allows additional features and functions to be added by using
importable modules. Some examples of available modules are referenced by the following import statements
in python script main.py.
# head -10 ./main.py
# import modules into Python script
import requests, json, http, httplib, urllib, urllib2
import os, sys, subprocess, math
import math, time
import logging
from simplejson import scanner
# setup logging to scapi.log
logging.basicConfig(level=logging.DEBUG
,filename='scapi.log'
,format='[%(asctime)s] %(levelname)s %(message)s')
Note: Logging defaults to capturing all information, warnings, and errors to the scapi.log file within the
current working directory.
