To fix this issue You can use a dict of tuples to keep track of the maximum number per channel type and the index of occurrence. The dict keys are ordered by their first insertions, but since you want the final order to follow where the occurrences of the maximum numbers are, the existing key should be deleted first in order for the new entry to be inserted at the right position whenever you find a new maximum number for a channel: code :
import re
d = {}
for i, channel in enumerate(channels):
type, n = re.findall('\d+[A-Z]*', channel)
n = int(n)
if type in d:
if n > d[type][0]:
del d[type]
else:
continue
d[type] = n, i
print([i for _, i in d.values()])
[4, 7, 9, 14, 15]
from collections import OrderedDict
d = OrderedDict()
