Python supports object-oriented programming and has a concise, readable, and easy-to-learn syntax. It is no wonder that it is one of the most popular programming languages. An integral part of Python are its built-in functions. You would have surely used some of these functions in your programs.
We've written a series of articles to help you learn and brush up on the most useful Python functions. In this article, we’ll learn about Python's sorted() function and how to use it.

Python sorted() function returns a sorted list with elements taken from an iterable object. The sorted() function sorts any sequence, like a tuple or a list, and always returns a list with the elements in sorted order. If you’re wondering how to sort a list in Python without the sort() function, sorted() is a way to go. Note that sorted() does not modify the original sequence.
The sorted() function in Python takes three parameters, out of which two are optional:
Here, we take a look at how you can use the Python function sorted() next time you need it:

Q1. Which is more efficient: sort() or sorted() function in Python?
The list function sort() is slightly faster and requires less memory than the built-in sorted() function in Python.
Q2. How do you sort a list in Python?
There are two ways to sort a list in Python: sort() and sorted(). You can use the sort() function to sort lists in sorted order. You can use sorted() to sort strings, tuples, lists, etc. If you don’t know how to use the sort function in Python for lists, you can simply use sorted().
Q3. What is the difference between sorted and sort in Python?
The sort() function just modifies the list it is called on, while the sorted() function needs to create a new list containing a sorted version. Hence, sort() is a bit faster and requires less memory. Also, sort() is just a list method and is only implemented for lists, while sorted() is a built-in function and accepts any iterable.
Q4. How do you sort by a function in Python?
You can sort on the basis of a function by specifying that function as a key in sorted(). Python’s sorted() function sorts any sequence like a list or a tuple. It always returns a sorted list made using the iterable object on the basis of a key without altering the original iterable object. This key refers to the function based on which the list is sorted.
Q5. Can you sort a list that contains strings and integers both using sorted() in Python?
No, you cannot sort a list that contains both string and numeric values.
