I have this scan output from Nmap. I want to parse the entire JSON and replace the '@' character with ''. how can I do this in python?

One possible way is to iterate the keys, and then to pop the item for the given key and assign it to the key without @, if the key starts with @, since you have nested structure, you need to go through these keys recursively

def recursive_replace(data):
    for key in data.keys():
        if key.startswith('@'):
            data[key[1:]] = data.pop(key)
            key = key[1:]
        if isinstance(data[key], dict):
            data[key]=recursive_replace(data[key])
    return data

OUTPUT:

>>> #assuming data holds the dictionary
>>> recursive_replace(data)
