Why does my code work?

Question

I tried to implement a bubble sort, but I do not understand how the code works without doing additional 'sweeps' (in the event the numbers are not sorted within a single pass.)

Answer 1

a.sort() actually sorts your list a inplace. That means it is automatically sorting it - not your algorithm. Change to

if sorted(a) == a:
...

Answer 2

Yeah, as ~ swim ~ said, something like this:

while sorted(a) != a:
for ...

Answer 3

Ok cool I was worried about it terminating too soon so I should use a while loop then

Answer 4

Thanks for the assist- I updated my code to reflect how many sweeps it took to complete

also updated code as it was counting each swap and not an entire for loop as a round

Answer 5

Noted and updated- now my code is back to not working like it should be :)
