During programming, there may be instances when you need a specific sort of variable. Typecasting is a technique that converts variables defined in one data type into another to match the operation performed by the code sample. Python is an object-oriented programming language with a diverse set of data types. Today, we'll go over the List and Tuple data types in Python, as well as various techniques for converting a list to tuple Python.
What is a list?
Python lists are equivalent to dynamically scaled arrays in terms of data structure. The most essential aspect of Python's list is that it does not have to be homogeneous all of the time. Integers, strings, and objects can all be included in a list. In contrast to an array carrying a single type of data, a Python list is an ordered and changeable collection of data items.
In Python, the list is the most versatile and widely used data structure. You can make a list by putting all of the elements in square brackets([]) and separating them with commas. All of these elements, like arrays, can be accessed further by the index number inside the square brackets.
What is tuple?
Tuples are a data structure in Python that allows you to store several components in a single variable. A tuple is homogeneous, just like a list data structure. As a result, a tuple can contain elements of different data types at once. You can make a tuple by putting all of the elements between parenthesis(()) and separating them with commas. Although parentheses are optional when working with tuples in Python, it is always a good idea to use them.
A tuple, unlike a list data structure, is immutable. As a result, after generating the tuple, you cannot add, change, or delete its elements.
Convert a list to a tuple.
As previously said, programming requires a variety of data operations.
Because each data structure's features and nature varies, you'll need to transform the variable from one data type to another at some point.
In the same way, we've included two of the most common and widely used ways for converting lists to tuples in Python programming.
Using the built-in function tuple()
The tuple() function is just one of many built-in functions in the Python language that make programming easier. Any iterate can be passed as an input to the tuple () function, which will convert it to a tuple object. If you want to convert a Python list to a tuple, you can use the tuple() function to pass the full list as an argument, and it will return the tuple data type as an output.
Example:
Input:
list1 = ['CodeAvail', '5', '3.58']
print(list1)
print(type(list1))
#convert list into tuple
tuple1 = tuple(list1)
print(tuple1)
print(type(tuple1))
Output:
['CodeAvail', '5', '3.58']
<type 'list'>
('CodeAvail', '5', '3.58')
<type 'tuple'>
Using a loop within a tuple
This approach is a little variant of the one described above. To convert a Python list to a tuple object, use a loop inside the built-in method tuple(). However, in comparison to other methods of type conversion, it is the least popular.
Example
Input:
list1 = ['CodeAvail', '5', '3.58']
print(list1)
print(type(list1))
#convert list into tuple
tuple1 = tuple(i for i in list1)
print(tuple1)
print(type(tuple1))
Output:
['CodeAvail', '5', '3.58']
<type 'list'>
('CodeAvail', '5', '3.58')
<type 'tuple'>
Final Words!
Despite the fact that List and Tuple are different data structures in Python, it is vital to understand their similarities and differences in order to use them effectively. This article explains the distinctions between a list and a tuple and several typical techniques for converting a Python list to a tuple.
