Youll know how to sort various types of data in different data structures, customize the. How to sort a list by the second element in tuple python. Not quite - is the reverse parameter set to True? Has a negative sign been used in the key parameter? What happens when those are both used? Use the key argument to select the elements at the specific indices in each tuple. In this step-by-step tutorial, youll learn how to sort in Python. To sort a given array of strings into lexicographically increasing order or into an order in.first city name (reverse alphabetically), then temperature (highest to lowest).Since sorted() returns a list, it must be converted to a string or tuple. On the other hand, you can specify not only lists but also strings and tuples to the sorted() function that creates a new sorted list.

When a list of tuples is sorted by the second value, the tuples' positions in the list are rearranged so that the second values of the tuples are in ascending order.first city name (reverse alphabetically), then temperature (lowest to highest).Weather = sorted_weather = sorted ( weather, key = lambda w : ( w, - weather ), reverse = True )
