Python Forum

i have a program that gives back a random list of numbers which i then sort using .sort() , but then this happened:

    list1 = [1,1,1,1,1]
    list2 = list1.sort[]
    print(list2)

output

None

why doesn't it just return

[1,1,1,1,1]

and what kind i do to bypass that problem?

That is because the list sort method sorts in place and returns None

list1 = [3, 4, 1, 2]
list2 = list1.sort()
print(list1)
print(list2)

Output:
[1, 2, 3, 4]
None

Use sorted if you want to get a sperate sorted version

list1 = [3, 4, 1, 2]
list2 = sorted(list1)
print(list1)
print(list2)

Output:
[3, 4, 1, 2]
[1, 2, 3, 4]

@menator01 Your code has two variables list1 & list2 that point to the same list object

list1 = [3, 4, 1, 2]
list2 = list1
list2.sort()
print(list1)
print(list2)

Output:
[1, 2, 3, 4]
[1, 2, 3, 4]

thank you

You really need to do more research into these simple questions. It is easy to google "Why does sort return None?", but I prefer reading the Python documentation because I always learn more. This talks about all the things you can do with lists, including sorting.
https://docs.python.org/3/library/stdtyp...#list.sort

That references a nice article all about sorting.
https://docs.python.org/3/howto/sorting....rtinghowto

You post a question here and you get your answer. Eventually. When you search the documentation you get the answer faster, and learn more that is related to your question.

Thank you, I'll check out the ressources you just gave me before asking question here in the future but trust me i search the web before asking question, i just don't seem to be good at it

Don't apologize, at one point or another we've all been there, and that is what this forum is all about!
