Python Tuple: Different ways to Create a Tuple and Iterate over it

Tuples are a type of variable that allows you to store multiple items in a single variable. Tuple is one of four built-in data types in Python that are used to store data collections. The other three are List, Set, and Dictionary, all of which have different qualities and applications. A tuple is a collection that is both ordered and immutable.

In this post we are going to discuss different ways to create the tuple and traverse through it.

Create a Tuple and Traverse it

1)List vs Tuple

  • Lists and tuples are represented in slightly different ways. Lists are commonly surrounded by the square bracket [], and elements are separated by commas. Tuples are surrounded by parenthesis (), and elements are separated by a comma. The parenthesis is optional, and these tuples are known as tuple packing.
  • It is the most significant distinh3ction between a list and a tuple, with lists being mutable and tuples being immutable. Lists are mutable, which means that the Python object can be modified after it is created, whereas tuples cannot be modified after they are created.
  • Tuples support fewer operations than lists. The built-in dir(object) function is used to retrieve all of the list and tuple’s supported functions.

2)Create a tuple of various types of elements

We can make a tuple of different elements by separating them with ‘,’ and wrapping them in braces i.e ( ).

Below is the implementation:

# Tuple
newtuple = ('hello', 3.5, 'this', 200, 'is', True, 'BTechGeeks')
# print tuple
print(newtuple)

Output:

('hello', 3.5, 'this', 200, 'is', True, 'BTechGeeks')

3)Create a tuple out of unpacked elements

We can also create a tuple from unpacked elements i.e without any braces just elements separated by comma.

Below is the implementation:

# Tuple
newtuple = 'hello', 3.5, 'this', 200, 'is', True, 'BTechGeeks'
# print tuple
print(newtuple)

Output:

('hello', 3.5, 'this', 200, 'is', True, 'BTechGeeks')

4)Create empty tuple

We can create tuple directly using () symbol.

Below is the implementation:

# creating new tuple
newtuple = ()
# print tuple
print(newtuple)

Output:

()

5)Convert list to tuple

We can convert list to tuple by using the syntax tuple(list_name).

Below is the implementation:

# given list
givenlist = [100, 'hello', 4.5, 'BTechGeeks']
# converting this list to tuple
newtuple = tuple(givenlist)
# print new tuple
print(newtuple)

Output:

(100, 'hello', 4.5, 'BTechGeeks')

6)Traverse the tuple

We can iterate over the tuple using for loop.

Below is the implementation:

# Tuple
newtuple = ('hello', 3.5, 'this', 200, 'is', True, 'BTechGeeks')
# Traverse the tuple
for i in newtuple:
    print(i)

Output:

hello
3.5
this
200
is
True
BTechGeeks
