Using sort (reverse=True) in a list

Installations & Python Packages
1

num_list = [34, 54, 78, 23, 54, 65, 67, 23, 56, 67, 23]


Type your code below

print(num_list.sort(reverse=True))





Q. Why does this gives "None" as output?

Hey Shirish,



Thanks a lot for replying. 



My doubt is why does "print(num_list.sort(reverse=True))" gives None as output?

Hi Mridul,

 

The return type of list.sort() is None. This is because the list is sorted in-place. What you want is sorted(list) or print the sorted list separately which returns the new sorted list.



As mentioned by Shirish, you can use the following code:

num_list = [34, 54, 78, 23, 54, 65, 67, 23, 56, 67, 23]



num_list.sort(reverse=True)



print(num_list)



You can also refer to this doc. 



Thanks,
