如何快速为python代码添加注释

#----->1.用一对"""括起来要注释的代码:
"""
  number = 23
  guess = int(raw_input('Enter an integer : '))
  if guess == number:
  print 'Congratulations, you guessed it.' # New blockstarts here
  print "(but you do not win any prizes!)" # New blockends here
  elif guess < number:
"""
#----->2.用一对'''括起来要注释的代码块:
'''
  print 'No, it is a little higher than that' #Another block
# You can do whatever you want in a block ...
else:
'''
#----->3.选中要注释的代码，按下ctrl+/注释:
#   print 'No, it is a little lower than that'
# # you must have guess > number to reach here
# print 'Done'
# # This last statement is always executed, after the ifstatement is executed
