Tuple

Tuple in python is used to store sequential multiple objects. All the objects are place within parenthesis [ ( ) ]. Tuple is similar to list but difference is that the list is mutable (changeable) and the tuple is immutable (unchanged).

Syntax:

T1= (1,”Raj”, 2) T2= (“red”, “green”, “blue”)

Indexing Process in Python:

The indexing process in tuple is similar to list. The objects in the tuple are store as a index wise automatically which is start from '0' and goes to length -1. The first object of tuple store into '0'th index and second object is '1' st index and so on.

For example if you want to store the ID number of  5 employees into Tuple as follows:

emp=(101,102,103,104,105)

Figure no. 1.1

Unlike other programming language Python provide negative indexes in tuple. The index start form right side. The right most index is -1 then -2 and so on.

Example 1:

tuple1=(10,20,30,40,50,60,70)
for i in tuple1:
    print(i)

Output:

10
20
30
40
50
60
70
>>> 

Example 2:

tuple1=(10,20,30,40,50,60,70)
for i in tuple1:
    del tuple1[1]
    print(i)

Output:

Traceback (most recent call last):
  File "G:\Python\tuple1.py", line 3, in <module>
    del tuple1[1]
TypeError: 'tuple' object doesn't support item deletion
>>> 

On the above example the output came error, because tuple does not support any del function and does not modified.

Example 3: Merging tow tuple:-

 t1=(1,2,3,4)

t2=(5,6,7,8)

print("Frist tuple")

for a in t1:

    print(a)

print("Second tuple")

for b in t2:

    print(b)

print("After marging")

for c in (t1+t2):

    print(c)

Output:

Frist tuple
