y = [1, 3, 2, 4]
x = y.sort()
print(x)
x is None. How come this sort of syntax works in, for example, Javascript, and not Python?

To initialize a list in Python assign one with square brackets, initialize with the list() function, create an empty list with multiplication, or use a list comprehension. The most common way to declare a list in Python is to use square brackets.
The sorted() function can accept three parameters: the iterable, the key, and reverse. In other words, the sort() method only works on lists, but the sorted() function can work on any iterable, such as lists, tuples, dictionaries, and others.
Python provides two ways to sort a list, the built-in list method list. sort() and the built-in function sorted() . Although both will sort the elements of a list, if used incorrectly they can produce unexpected or undesired results.
Python has two sort functions; one function that sorts a list in-place and the other sort function “sorted” that creates a new sorted list. In this post, we will see examples of “in-place” sorting.
If you want to take an iterable and return a new, sorted list of its items, use the sorted builtin function. sort () doesn't return any value while the sort () method just sorts the elements of a given list in a specific order - ascending or descending without returning any value. So problem is with answer = newList.sort () where answer is none.
sort() doesn't return any value while the sort() method just sorts the elements of a given list in a specific order - ascending or descending without returning any value. So problem is with answer = newList.sort() where answer is none. Instead you can just do return newList.sort(). The syntax of the sort() method is:
This is possible due to the fact that the data types are dynamically typed in python. This is why P ython is known as a dynamically typed programming language. If you want to assign the same value to more than one variable then you can use the chained assignment: Integers, decimals, floats are supported. Longs are also supported.
list.sort sorts the list in place, i.e. it doesn't return a new list. Just write return sorted (newList) is shorter. Doesn't matter here since the variable is local, but in-place sort could change a shared variable in some cases.
sort (and reverse) change the list in-place.
If you want, you can use sorted:
x = sorted(y)
This is explained in the section Data Structures in the documentation.
