Convert List to Tuple in Python
Sometimes, because of the differences between a List and Tuple, you may need to convert a Python List to a Tuple in your application.
In this tutorial, we shall learn how to convert a list into tuple. There are many ways to do that. And we shall discuss the following methods with examples for each.
- Use tuple() builtin function.
- Unpack List inside parenthesis.
Use tuple() builtin function
tuple() builtin function can take any iterable as argument, and return a tuple object.
In the following example, we shall take a list of strings, and convert it into a tuple.
Python Program
#take a list of elements
list1 = ['apple', 'banana', 'cherry']
#convert list into tuple
tuple1 = tuple(list1)
print(f'Tuple : {tuple1}')
print(type(tuple1))Output
Tuple : ('apple', 'banana', 'cherry')
<class 'tuple'>You may observe in the output that we have printed the type of the variable tuple1, which is <class 'tuple'>.
Unpack List inside Parenthesis
We can also unpack the items of List inside parenthesis, to create a tuple.
In the following program, we have a list, and we shall unpack the elements of this list inside parenthesis.
Python Program
#take a list of elements
list1 = ['apple', 'banana', 'cherry']
#unpack list items and form tuple
tuple1 = (*list1,)
print(f'Tuple : {tuple1}')
print(type(tuple1))Output
Tuple : ('apple', 'banana', 'cherry')
<class 'tuple'>Summary
In this tutorial of Python Examples, we learned how to convert a Python List into Tuple in different ways, with the help of well detailed example programs.
