Does that help It might be better to simplify things by not generating those extra zeroes in the first place:
code :
def bin(x):
    prefix = ("-" if x < 0 else "")
    x = abs(x)
    bits = []
    while x:
        x, bit = divmod(x, 2)  # division and remainder in one operation
        bits.append(str(bit))
    # Flip the bits so the LSB is on the right, then join as string
    bit_string = ''.join(bits[::-1])
    # Form the final string
    return f"{prefix}0b{bit_string}"

print(bin(8314))
0b10000001111010

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()

may help you . New to python and I want to remove the prefix of two stings. Just leaving everything before the J and removing the .json. , You can use split() in a list-comprehension:
code :
name = ['190523-105238-J105150.json',
'190152-105568-J616293.json']

print([x.rsplit('-', 1)[1].split('.')[0] for x in name])
# ['J105150', 'J616293']

Any of those help Loop through the array and check if each element is empty. If it's not, add its position to one array and its value to another array:
