5 Examples of Python List of Tuples

5 Examples Of

Hey, readers! In this article, we will be focusing on Python List of Tuples.

What is Python List and Tuple?

Python List is a data structure that maintains an ordered collection of mutable data elements.

list-name = [ item1, item2, ....., itemN]

The elements in the list are enclosed within square brackets [].

Python Tuple is an immutable data structure whose elements are enclosed within parenthesis ().

tuple-name = (item1, item2, ...., itemN)

Python List of Tuples

We can create a list of tuples i.e. the elements of the tuple can be enclosed in a list and thus will follow the characteristics in a similar manner as of a Python list. Since, Python Tuples utilize less amount of space, creating a list of tuples would be more useful in every aspect.


LT_data = [(1,2,3),('S','P','Q')]
print("List of Tuples:\n",LT_data)


List of Tuples:
 [(1, 2, 3), ('S', 'P', 'Q')]

Python list of tuples using zip() function

Python zip() function can be used to map the lists altogether to create a list of tuples using the below command:


The zip() function returns an iterable of tuples based upon the values passed to it. And, further, the list() function would create a list of those tuples as an output from the zip() function.


lst1 = [10,20,30]
lst2 = [50,"Python","JournalDev"]
lst_tuple = list(zip(lst1,lst2))


[(10, 50), (20, 'Python'), (30, 'JournalDev')]

Customized grouping of elements while forming a list of tuples

While forming a list of tuples, it is possible for us to provide customized grouping of elements depending on the number of elements in the list/tuple.

[element for element in zip(*[iter(list)]*number)]

List comprehension along with zip() function is used to convert the tuples to list and create a list of tuples. Python iter() function is used to iterate an element of an object at a time. The ‘number‘ would specify the number of elements to be clubbed into a single tuple to form a list.

Example 1:

lst = [50,"Python","JournalDev",100]
lst_tuple = [x for x in zip(*[iter(lst)])]

In the above example, we have formed a list of tuples with a single element inside a tuple using the iter() method.


[(50,), ('Python',), ('JournalDev',), (100,)]

Example 2:

lst = [50,"Python","JournalDev",100]
lst_tuple = [x for x in zip(*[iter(lst)]*2)]

In this example, two elements are contained inside a tuple to form a list of tuple.


[(50, 'Python'), ('JournalDev', 100)]

Python list of tuples using map() function

Python map function can be used to create a list of tuples. The map() function maps and applies a function to an iterable passed to the function.

map(function, iterable)


lst = [[50],["Python"],["JournalDev"],[100]]
lst_tuple =list(map(tuple, lst))

In this example, we have mapped the input list to the tuple function using map() function. After this, the list() function is used to create a list of the mapped tuple values.


[(50,), ('Python',), ('JournalDev',), (100,)]

Python list of tuples using list comprehension and tuple() method

Python tuple() method along with List Comprehension can be used to form a list of tuples.

The tuple() function helps to create tuples from the set of elements passed to it.


lst = [[50],["Python"],["JournalDev"],[100]]
lst_tuple =[tuple(ele) for ele in lst]


[(50,), ('Python',), ('JournalDev',), (100,)]
