Okay, so if you only want to sort a list of numbers, Python has a built in function that does all the hard work for you. Since a tuple is basically like an array that is not modifiable, we'll treat it almost the same as a list. They are two examples of sequence data types (see Sequence Types — list, tuple, range).

Convert a list into tuple of lists in Python, Convert a nested list into a flat list in Python. generate link and share the link here. Swag is coming back! We can use it as follows: Output: Both of them have an optional parameter key that expects a function. Because some downstream code may be expecting to handle tuple and the current list has the values for that tuple. Lists can be used to store any data type or a mixture of different data types. It is called sequence unpacking.5. List and tuples comes under a class of data structure called *array*. Python. List and Tuple in Python are the class of data structure. Data Structures — Python 3.7.4rc1 documentation This post describes the following contents.Basics of unpacking a tuple and a list Unpack a nested tuple and list … For example − When the above code is executed, it produces the following result − This Python Data Structure is like a, like a list in Python, is a heterogeneous container … edit Initialize List of Tuple. The tuples and list are different in following ways : The tuples are immutable sequences while list are mutable. Tuples are just like lists with the exception that tuples cannot be changed once declared. Python Dictionary; Python Tuple; 1. This is a straight way of applying the tuple function directly on the list. Still, there is a significant difference between them, and that difference is tuples are immutable. Strengthen your foundations with the Python Programming Foundation Course and learn the basics. Should you choose Python List or Dictionary, Tuple or Set? It is represented as a collection of data points in square brackets. Do not use this if the tuple may already be known to some other part of the code. And tuple can be considered as an item. Because tuples are supposed to be immutable, this should only be used if there is only one reference to the object. Typecasting to tuple can be done by simply using tuple(list_name). Python provides another type that is an ordered collection of objects, called a tuple. A small variation to the above approach is to use a loop inside tuple() . Array is a collection of elements, and ordering or positioning of these element is as important as the element itself.
