How to sort list from latest user input to last

Question

Hey guys I want the list that the user is creating with input to print in the order from latest entry to first entry..

the code I have right now does it for a few posts then it prints the list in some weird order

all_status_updates = []


def status():
    while True: 
        status = input("Type Status Update Here...\n")
        if status != "exit":
            all_status_updates.append(status)
            all_status_updates.sort(reverse = True) 
            print(all_status_updates)
        elif status == "exit":
            break
status()

Can you please show us the output? Are you confused by sorting strings? — Fourier, Dec 17 '19 at 09:38

When you sort, it will put the inputs in alphabetical order. If you just want to reverse the list, use myList.reverse() EDIT : reverse only at the end to have the expected result.

all_status_updates = []


def status():
    while True: 
        status = input("Type Status Update Here...\n")
        if status != "exit":
            all_status_updates.append(status)
            print(all_status_updates)
        elif status == "exit":
            break
    all_status_updates.reverse()
    print(all_status_updates)

status()

this does not do it instead it does the latest entry and right next to it is the first entry and so on I tried this before posting here – hauntboy Dec 17 '19 at 09:47
Reversing the list within each iteration will not show the desired result. – AnsFourtyTwo Dec 17 '19 at 09:59
You are both right, I edited my answer with the reverse only once at the end – Phoenixo Dec 17 '19 at 10:24

Several things, which might not work in your example:

You do not need to sort(), but to reverse the order of your list. For this you can use list slicing
You should not name the variable for user input status, which is the same name as the function

def status():

    all_status_updates = []
    while True: 
        stat = input("Type Status Update Here...\n")
        if stat != "exit":
            all_status_updates.append(stat)
            print(all_status_updates[::-1])
        elif stat == "exit":
            break

status()

OUTPUT

Type Status Update Here...
a
['a']
Type Status Update Here...
b
['b', 'a']
Type Status Update Here...
c
['c', 'b', 'a']
Type Status Update Here...
d
['d', 'c', 'b', 'a']
Type Status Update Here...
e
['e', 'd', 'c', 'b', 'a']
Type Status Update Here...
f
['f', 'e', 'd', 'c', 'b', 'a']
Type Status Update Here...
exit

This does not change anything? – Fourier Dec 17 '19 at 09:38
thank you so much Simon! and will do thanks again for all the help – hauntboy Dec 17 '19 at 09:38
Did you read the question ? "I want the list that the user is creating with input to print in the order from latest entry to first entry". – bruno desthuilliers Dec 17 '19 at 09:40
@hauntboy this does not answer your question. And it will actually make no difference (except for saving a couple cpu cycles). – bruno desthuilliers Dec 17 '19 at 09:41
I'm very sorry, I was so convinced my solution would work, that I didn't test it. Now I did and now it should show the right behaviour. – AnsFourtyTwo Dec 17 '19 at 09:57
thanks but Simon I want the list to print after every entry not just at the end yours works but without printing after every entry which is not what I'm going for – hauntboy Dec 17 '19 at 10:02
In this case, you cannot use `reverse()`, as it reverts the list inplace. You need to use list slicing in this case. I'll edit. – AnsFourtyTwo Dec 17 '19 at 10:05
that did it weird I tried the slicing and it did not work for me earlier because I was adding the slicing in the wrong place thanks Simon! appreciate it – hauntboy Dec 17 '19 at 10:10
