How to delete specific values in a list?

Question

I have a list which looks like this:

my_list = 
[['UK', 'Manchester City', 'Blue', '1','2','B'],
['ES', 'FC Barcelona', 'Blue', '2','1','C'], 
['IT', 'Juventus', 'White', '3','2','A'],
['DE', 'Borussia Dortmund', 'Yellow', '4','1','A']]

Now I want to edit my_list and actually delete the values in index0,3,4 and 5.

This is my expected output:

  my_list = 
[['Manchester City', 'Blue'],
['FC Barcelona', 'Blue'], 
['Juventus', 'White'],
['Borussia Dortmund', 'Yellow']]

This is the code I tried:

for list in my_list:
    for idx in [0,3,4,5]:
        del list[idx]       
        
print(my_list)

This is the output I get:

IndexError: list assignment index out of range

You get an exception because you try to change the length from a list (del) inside to a for loop. — G.Mich, Oct 06 '20 at 09:00

Try

my_list = [['UK', 'Manchester City', 'Blue', '1', '2', 'B'],
           ['ES', 'FC Barcelona', 'Blue', '2', '1', 'C'],
           ['IT', 'Juventus', 'White', '3', '2', 'A'],
           ['DE', 'Borussia Dortmund', 'Yellow', '4', '1', 'A']]

new_list = [lst[1:3] for lst in my_list]
print(new_list)

output

[['Manchester City', 'Blue'], ['FC Barcelona', 'Blue'], ['Juventus', 'White'], ['Borussia Dortmund', 'Yellow']]

What if I had to delete for example index `0`, `2` and `4`? – NorthAfrican Oct 06 '20 at 09:13
@NorthAfrican In this case the code would be different. – balderman Oct 06 '20 at 09:27
Can you show how it would be? – NorthAfrican Oct 06 '20 at 09:36
@NorthAfrican see https://pastebin.pl/view/813a1d04. Feel free to up vote. – balderman Oct 06 '20 at 09:42
I dont see any code when I click that link.... – NorthAfrican Oct 06 '20 at 09:46

Thank you, can you explain to me what you did in a private chat? – NorthAfrican Oct 06 '20 at 09:55
@NorthAfrican Start by reading the code few times. For the lines that you dont understand look around in the internet. If by the end of the process you will still have questions you can ask in stackoverflow. – balderman Oct 06 '20 at 09:57
thank you my Indonesian brother :) – NorthAfrican Oct 06 '20 at 09:58
