I am new here and new to Python.
I would like to know if anyone knows how to sort a generated list by size.

I have a piece of the code here. The sorting should be from small to large.
6.52, 26.4

for i in x:

    pfad = (i)

    title=(i)

    size = (i)

    bild = (i)



    liste=('<a href="' + pfad + '">' + title + '<br>;' + size + '<div><img src="' + bild + '" /></div></a></br>')

    print(liste)



    <a href="URL/">Title<br>;26.14;GB<div><img src="https://URL.jpg" /></div></a></br>

    <a href="URL/">Title<br>;6.52;GB<div><img src="https://URL.jpg" /></div></a></br>

    <and much more>

I tried with

liste = csv.reader(liste,delimiter=';')

liste = sorted(liste,key=operator.itemgetter(1))



for i in liste:

    print (i)

and other things (lambda and so on) but it did not work.
Does anyone have a suggestion?

If you are sure of getting just a simple list like [1, 2, 3, 4] then, using sorted() method is in ascending order by default, so no need of a key.

liste = csv.reader(liste,delimiter=';')

liste = sorted(liste)



for i in liste:

    print (i)

for descending order add reverse = True into sorting method.

You can retrieve an element from a list with itemgetter() like this:

>>> from operator import itemgetter

>>> z = ['foo', 'bar','qux','zoo']

>>> itemgetter(1)(z)

If still you want to sort with itemgetter you need to have atleast 2 dimensional list

>>> a = [[1,2,1,2,3,4,5,6,3,4],[1,2,3,4],[4,5,7,8], [1,2,2,3,4,5,4,65,3,4,3,2,2]]

>>> sorted(a, key=itemgetter(3))

[[1, 2, 1, 2, 3, 4, 5, 6, 3, 4], [1, 2, 2, 3, 4, 5, 4, 65, 3, 4, 3, 2, 2], [1, 2, 3, 4], [4, 5, 7, 8]]

>>>

But I assume that csv reader will return a dictionary most probably

liste = csv.reader(liste,delimiter=';')

liste = sorted(liste, key=lambda k: k['name of the column'])



for i in liste:

    print (i)

thank you for your help.

I have now a example code.

#!/usr/bin/env python3

import csv



liste = ['Name:1 ;26.1; E-a', 'Name:2 ;262; E-b', 'Name:3 ;7.92; E-c', 'Name:4 ;4.6; E-d', 'Name:5 ;4.74; E-e']



liste_csv = csv.reader(liste,delimiter=';')

liste_sort = sorted(liste_csv, key=lambda k: k[1])



for i in liste_sort:

    print (i)

I get the following issue

['Name:1 ', '26.1', ' E-a']

['Name:2 ', '262', ' E-b']

['Name:4 ', '4.6', ' E-d']

['Name:5 ', '4.74', ' E-e']

['Name:3 ', '7.92', ' E-c']

But I want

['Name:4 ', '4.6', ' E-d']

['Name:5 ', '4.74', ' E-e']

['Name:3 ', '7.92', ' E-c']

['Name:1 ', '26.1', ' E-a']

['Name:2 ', '262', ' E-b']

How can I do that?

Sorry for the bumpy start.
I just started learning Python.
