Input and print

Some useful ways to enter and print

Input:

Differences between input( ) and raw_input( ):

String str we input:

• By input( ): str can't contain blank space
• By raw_input( ): str can contain blank space, so we can extract some items by using str.split(' ')
  Example1:Enter some integers separated by a ( or some ) space .
  '''
  import string
  str = raw_input() #str = '45 12 32 65'
  chars = str.split(' ')
  ints = []
  for i in chars:
  ints.append(int(i)) # string to int function: int(str)
  print ints #[45,12,32,65]
  '''

print:

• Stand style of print integer:
  Example : print '%d * %d = %-3d"%(i,j,result) #%-3d Align right 3 characters.
• Several items in a common raw:
  print item1,item2, # a , followed items
