Using sort() Function

In Python, List has a native function to sort its items - sort() function. It can be used in different use-cases to sort the list. It is a very powerful function and can do custom sorting too by providing lambda function.

Key Note:

  • The sort() function modifies the list in-place, therefore the list itself is modified and the function has no return value.
  • It is a method of the list ****class and therefore can only be used with lists.
  • By default, it sorts in ascending order

Sort List containing numbers (Integers and decimals)

Let's review an example of sorting a list containing numbers. Sorting integers is quite simple as it compares using comparison operator and sorts accordingly.

Numbers = [1,32,8.4,5]
Numbers.sort()
print(Numbers)
#[1,5,8.4,32]

Make sure all items are numbers since number and string cannot be compared via comparison operator "<".
