Tuples in Python

Tuples are a special data structure similar to the list data structure. If we relate tuple to list, tuples are faster because of nature of tuples as immutable.

Syntax

tpl1 = (1, 2, 3)

ex:

tpl1 = (1, 2, 3)

print tpl1

tpl1 = 100, 20,30,'Ram','hello!'

print tpl1

print tpl1[0]

len(tpl1)

tpl1.index(30)

print tpl1[2:3]

Tuple Manipulation functions

( )                                   An empty tuple

tpl1 = (0,)                       A one-item tuple

tpl2 = (0, 'ax', 1, 3)        A four-item tuple

tpl1[i]                                       Indexing

tpl1[i:j]                          slicing

len(tpl1)                         length

tpl1 + tpl2                      Concatenation

tpl2 * 3                          repetition

for x in tpl2                     Iteration

tpl1.count(1)                  Occurrence of numbers in tuple

tpl1.index(2)                 Index number of the value “2” in tuple
