Python lists have a built-in list. sort() method that modifies the list in-place. There is also a sorted() built-in function that builds a new sorted list from an iterable.
Python sorted() Function The sorted() function returns a sorted list of the specified iterable object. You can specify ascending or descending order. Strings are sorted alphabetically, and numbers are sorted numerically. Note: You cannot sort a list that contains BOTH string values AND numeric values.
Use the sort() Function to Sort a List of Lists in Python. The sort() method sorts the list of lists in Python according to the first element of each inner list. This method makes changes in the original list itself. We use the reverse parameter to sort in descending order.
just like this:
sorted(lst, reverse=True)
Sort in place? Use:
lst.sort(reverse=True)
