If you are already aware of it, feel free to jump to the solution down below. If you are a beginner, then I highly recommend this book.Here we have tried to compile a guide about how to go about sorting with simple real-life practical examples, which we hope will ease your way in understanding the sorting all the way through.īefore getting started with the actual tutorial, it is important to understand and clear the concepts. It means slice the list, starting at the first character, ending at the last character and with step size of -1 (reverse). The technique of slicing is used on the list. You can sort the list in a more elegant way: 1 The method list() converts the output of reversed() and converts it to a list object. But, the function does not return a list object but an iterator. Then it’s given to the function reversed() which takes a list as parameter.
To sort in reverse order, combine it with the method reverse() 1Īll of the numbers will be shown in reverse order. You do not need to use a return variable when doing this, because lists are objects (more on this later in the OOP section). sort() method, you can sort a list with a number of items. This will output all numbers in low to high order.ĭo you have a list of strings? Strings can also be sorted. We do not need to save the return variable, simply calling the method is enough. Then call the sort method on the list object. We define a list (x) with a bunch of numbers.
