mutable values to string items?

[DeaD_EyE]

channels = [
    ['#channel1', 0],
    ['#channel2', 0],
    ['#channel3', 0],
]

Assigning the first element from channels to a name:

first = channels[0]

Assigning a list to the first element of the list channels:

channels[0] = ["channel33", 33]

If you do not want to use integer indices, then use a dict.

channels = {
    '#channel1': 0,
    '#channel2': 0,
    '#channel3': 0,
}

channels['#channel4'] = 33
channels['#channel1'] = 1

for name, value in channels.items():
    print(name, "->", value)

Output:
#channel1 -> 1
#channel2 -> 0
#channel3 -> 0
#channel4 -> 33

Getting all values, but not the channels (keys of the dict):

print(list(channels.values()))

Output:
[1, 0, 0, 33]

If you use for your program the wrong data structures, then handling the data is very complicated.
