Python Tuples

Python tuple created inside the rounded bracket and it unchangeable ordered.

How to declare python tuple?

>>> tup = (“Welcome”, “to”, “the”, “Codersarts”)

Accessing Tuple item

The item of tuple is accessed using the index value.

It works as per above list accessing process like that –

>>> tup[2]

Output:

the

Extract element using the negative indexing

It works like a list in python, the negative index starts from last.

>>> tup[-1]

Output:

Codersarts

Tuple with range

Like list, the tuple is also extracted the element from string using the given range 

>>> string = ("hi", "this", "is", "codersarts", "tutorial")

>>> string[2:4]

Output:

is codersarts tutorials

​

Negative indexing is also used like list.

How to change tuple value

Once a tuple is created it is not changed, it can be changed using the list.

a = ("Hi", "this", "is", "codersarts")
b = list(x)
b[1] = "hello"
a = tuple(b)
print(x)

Output:

hello this is codersarts

Passing tuple with the loop

The tuple is passed from loop like list.

a = ("Hi", "this", "is", "codersarts")

for x in a:
  print(x)

Output:

Hi

this

is

codersarts

Finding the length of tuple

a = ("Hi", "this", "is", "codersarts")

print(len(x))

Output:

4

Add item to tuple

Once a tuple is created not add another item to the tuple.

Removing item from tuple

We can't remove the item from tuple after it is created.
