#lets define a simple function def main(): try: #mathFail = 1/0 # this will give an error which can be catched if 1<2: logging.debug('Entered into one of the if statements') print('we are in the IF STATEMENT') #this error will not break our entire script so we will catch the error and give some info try: urllib2.urlopen('http://www.google.com').read() logging.info('Opened url fine') except Exception as e: logging.error('urllib2 url visit failed and the reason was %s' % str(e)) else: logging.debug('Entered into the else statement') print('We are in the ELSE STATEMENT') except Exception as e: print(str(e)) logging.critical(e) |
