I have a data structure as follows,

data = {
    '0_0': [('0_0', 0), ('0_1', 1), ('0_2', 2)],
    '0_1': [('0_0', 1), ('0_1', 0), ('0_2', 1)],
    '0_2': [('0_0', 2), ('0_1', 1), ('0_2', 0)],
}

How to delete tuple from lists by given key? For example I wrote a function as follows,

def remove_all_acs(
    dictionary,
    delete_ac
):
    for key in dictionary:
        acs = dictionary[key]
        for ac in acs:
            if ac[0] == delete_ac:
                acs.remove(ac)
                break

    return dictionary

It’s my expected output and returns a result as follows,

{
    '0_0': [('0_1', 1), ('0_2', 2)],
    '0_1': [('0_1', 0), ('0_2', 1)],
    '0_2': [('0_1', 1), ('0_2', 0)]
}

It works but is not effective on large lists. Do you have any idea? Thanks in advance.

In addition you can create large dataset using this code,

def generate(size, max_connections):
    data = {}
    keys = [f'{i}_{j}' for i in range(size) for j in range(size)]
    
    for key in keys:
        connections = random.randint(1, min(max_connections, 10))
        data[key] = [
            (random.choice(keys), random.randint(1, 10)) 
            for _ in range(connections)
        ]
    
    return data

data = generate(200, 10)
