fixed the issue. Will look into that further If you really want to summ up flight-numbers, you can create tuples from your raw data directly and summ them into a dict: (using a defaultdict would be better)
t = ['AI077:077', 'AI077:077', 'AI077:077', 'AI077:077', 'AI567:567',
     'AI567:567', 'BA896:896', 'SI267:267', 'SI267:267', 'SI267:267']

trimmed = [(y[0:5],int(y[6:])) for y in t]

summs = {}
for flight,price in trimmed:
    summs[flight] += price

{'BA896': 896, 'SI267': 801, 'AI077': 308, 'AI567': 1134}
               #flight : from : to : seat-number
ticket_list= ["AI567:MUM:LON:014", "AI077:MUM:LON:056", "BA896:MUM:LON:067",
              "SI267:MUM:SIN:145", "AI077:MUM:CAN:060", "SI267:BLR:MUM:148", 
              "AI567:CHE:SIN:015", "AI077:MUM:SIN:050", "AI077:MUM:LON:051",

from collections import Counter
c = Counter ((t.split(":")[0] for t in ticket_list))

# sold tickets per flight
Counter({'AI077': 4, 'SI267': 3, 'AI567': 2, 'BA896': 1})
from itertools import groupby

# if you need the tickets as well:
grp = groupby(sorted(ticket_list), lambda x:x[:6])

for g in grp:
    key, seats = g
    seats = list(seats)
    print(f"Flight: {key} has sold seats {len(seats)}: {','.join( x.split(':')[-1] for x in seats)}")

Flight: AI077: has sold seats 4: 060,051,056,050
Flight: AI567: has sold seats 2: 015,014
Flight: BA896: has sold seats 1: 067
Flight: SI267: has sold seats 3: 148,145,146

Natural sort of a list of lists based on an alphanumeric string within sub-list?

Tag : python , By : KL.

hope this fix your issue Using the natural_sort function from this answer you can do something like this:
import re
from string import punctuation as punc, whitespace as wt
from pprint import pprint

def natural_sort(l): 
    convert = lambda text: int(text) if text.isdigit() else text.lower() 
    alphanum_key = lambda key: [ convert(c) for c in re.split('([0-9]+)', key) ] 
    return sorted(l, key = alphanum_key)

def key(seq):                                           
    convert = lambda text: int(text) if text.isdigit() else text.lower() 
    return [convert(c.translate(None, punc+wt)) for c in re.split('([0-9]+)', seq)]
>>> my_list = [[ 1,   'C1', 'DW-00232'],
 [3,    'C11, C32, C46', 'DW-6546'],
 [7,    'C16, C17, C18, C19, C20, C21, C25', 'DW-545'],
 [5,    'C2, C3, C4, C5, C63', 'DW-7657'],
 [1,    'C26', 'DW-0056'],
 [2,    'C59, C60', 'DW-23424'],
 [5,    'C6, C13, C24, C30, C64', 'DW-5345']]
>>> new_lis = [x[:1] + [", ".join(natural_sort(x[1].split(', ')))] + x[2:]
                                                                for x in my_list]
>>> new_lis.sort(key = lambda x:key(x[1]))               
>>> pprint(new_lis)
[[1, 'C1', 'DW-00232'],
 [5, 'C2, C3, C4, C5, C63', 'DW-7657'],
 [5, 'C6, C13, C24, C30, C64', 'DW-5345'],
 [3, 'C11, C32, C46', 'DW-6546'],
 [7, 'C16, C17, C18, C19, C20, C21, C25', 'DW-545'],
 [1, 'C26', 'DW-0056'],
 [2, 'C59, C60', 'DW-23424']]

How to compare an alphanumeric string with a List<string> which also has alphanumeric values C#

Tag : chash , By : Karina

may help you . Why you want use Linq for this simple task? You can simply use List.Contains(item) method
        List<string> lollipop = new List<string>();
        //Do something
         //DO something
        //Something else

What would be the regex for this pattern; (alphanumeric.alphanumeric.alphanumeric)?

wish helps you I am new to regex. What would be the regex for this pattern? , How about:

Hope that helps I think you are looking in the wrong list. Instead of looking in the index, try looking in content
with open('test.txt', "r") as file:
    for line in file:
        print find_element_in_list(content, line.rstrip('\n'))
