Sorting Lists of Strings in Python
One of the common tasks in programming is sorting text data. In Python, sorting a list of strings can be achieved using various techniques.
Basic Sorting
The simplest method is to use the sort() method on the list itself. This sorts the list in-place, modifying the original order.
