Python Tuples

• Accessing Values in Tuples:

  #!/usr/bin/python
  
  tup1 = ('physics', 'chemistry', 1997, 2000);
  tup2 = (1, 2, 3, 4, 5, 6, 7 );
  
  print "tup1[0]: ", tup1[0]
  print "tup2[1:5]: ", tup2[1:5]

  Output

  tup1[0]: physics
  tup2[1:5]: [2, 3, 4, 5]

  Updating Tuples:

  #!/usr/bin/python
  
  tup1 = (12, 34.56);
  tup2 = ('abc', 'xyz');
  
  # Following action is not valid for tuples
  # tup1[0] = 100;
  
  # So let's create a new tuple as follows
  tup3 = tup1 + tup2;
  print tup3;

  Output

  (12, 34.56, 'abc', 'xyz')

  Delete Tuple Elements:

  #!/usr/bin/python
  
  tup = ('physics', 'chemistry', 1997, 2000);
  
  print tup;
  del tup;
  print "After deleting tup : "
  print tup;

  Output

  ('physics', 'chemistry', 1997, 2000)
  After deleting tup :
  Traceback (most recent call last):
  File "test.py", line 9, in < module >
  print tup;
  NameError: name 'tup' is not defined

  No Enclosing Delimiters:

  #!/usr/bin/python
  
  print 'abc', -4.24e93, 18+6.6j, 'xyz';
  x, y = 1, 2;
  print "Value of x , y : ", x,y;
  print var;

  Output

  abc -4.24e+93 (18+6.6j) xyz
  Value of x , y : 1 2
