By default, the sorted() function will return a list sorted in its natural sort order (which is generally what we want for numbers and strings). Second, sort the keys alphabetically using sorted (key_value) function & print the value corresponding to it. The teacher wants us to sort 3 numbers in acceding order without using the sort function built into python. This simple sorting algorithm iterates over a list, comparing elements in pairs and swapping them until the larger elements "bubble up" to the end of the list, and the smaller elements stay at the "bottom". In this program, we store the string to be sorted in my_str. You can also make a function to decide the sorting criteria (s).
Python has its own implementation of sort () function and another is sorted () function where sort () will sort list whereas, sorted function will return new sorted list from an iterable. In this tutorial we’ve taken a look at how python makes sorting lists (and other iterables) easy. sort_values(by=0, inplace=True) See the docs for more info. Sorting is also used to represent data in more readable formats.
