Help appreciated to simplify code! Sort input numbers.

Question

I coded a little program that receives input numbers from user and sorts them from low to high in a list.
As it is, the program works all right but I had to include a few IFs to manage special cases I didn't know how to include in the main block... (e.g. when it is the first number in the list, or the highest/lowest yet to appear...)
Any ideas very much appreciated!

Answer 1

Actually I didn't know there were built in sorting methods... I'm quite new to python! I'll investigate those but for now I would like to optimize my own sorting code! Many thanks

Answer 2

If you want to insert each element in place at the moment it's given, keeping things simple, I would go with a for loop:

for i in range(len(thatlist)):
if n<thatlist[i]:
thatlist.insert(i, n)
break
else:
thatlist.append(n)

The else part is outside of the for loop and will only be executed if there is no break.

Your code works fine. Because the SoloLearn online compiler requires all inputs to be entered at once, they have to be on separate lines. Try this:
2 (enter)
4 (enter)
3 (enter)
quit (submit)
you should get [2, 3, 4]
(otherwise you get an EOFError)
You won't get that problem with, e. g. IDLE, VS Code or Pydroid3. See https://www.google.ca/search?q=sololearn+input+problem&oq=sololearn+input+problem&aqs=chrome..69i57j33.14884j0j4&sourceid=chrome-mobile&ie=UTF-8

Answer 4

Do you explicitly want to write your own sorting method instead of using the built-in ways?

Ok, many thanks for your help!
