In list [5,8,2,3,1] sort without user defined functions ?

Question

Note .... Even len() also don't use

Answer 1

A bit late as always...

lst = [2,6,8,4,3,2,9,15,0]
len_ = (sum([1 for i in lst])) # shortest version to get len
# or
len_ = 0
for i in lst:
len_ += 1
res = []
count = 0
while count < len_:
res.append(lst.pop(lst.index(min(lst))))
count += 1
print(res)

Answer 2

Dirk, sorted output for integers by using set() is true, but not for float and string:

x = [5, 8, 2, 3, 1]
print(set(x)) # output is {1, 2, 3, 5, 8}

y = [10.5, 3.5, 2.0]
print(set(y)) # output is {2.0, 10.5, 3.5}

z = ['g', 'a', 'x', 'b']
print(set(z)) # output is {'g', 'b', 'a', 'x'} but can vary

Answer 3

Here a clanky len version, without any functions or methods. ;-)

length = 0
while True:
try:
your_list[length]
length += 1
except:
break

Another version working with slice:

length = 0
clone = your_list[:]
while clone:
clone = clone[1:]
length += 1

Answer 4

Do you mean 'without built-in functions'?

Answer 5

I'm only telling you so that you get a good answer more easily.

I think the easiest (not the quickest) sorting algorithm will be bubble sort.

You can try to implement that in Python.

Answer 6

I think for this process INSERTION SHOT would be more easy and fast

Answer 7

Ok thanks

Answer 8

If you don't need the output to be a list, you can use set([5,8,2,3,1])

Answer 9

Good question

Answer 10

Yes

Answer 11

I did using length any other #program to sort the values
l = [5,8,2,3,1]

for x in range(len(l)):
b = 0
a = 1
for i in l:
if a == len(l):
break
if l[b]<l[a]:
a += 1
b += 1
continue
elif l[b] > l[a]:
c = l[a]
l[a] = l[b]
l[b] = c
a += 1
b += 1
elif l[a] == l[b]:
a += 1
b += 1
continue
print(l)

Answer 12

Then you should edit your question text, so that people can see immediately what you really want.

Also you could add more meaningful tags, 'sort' as a minimum.

Answer 13

It's my first post i will learn all ..

Answer 14

Hm, so you already have a working version. You only need to get rid of the len?

Answer 15

len_ = 0
for i in lst:
len_+=1

lol.

I did some serious code babble up there, Lothar. 😅🤣

Answer 16

Lothar fantastic solution. Very Pythonic!

Answer 17

How to get the input as character

Answer 18

Yes we can sort using <list or list_variable>.sort() function which is inbulit function
