Solve the following python programming problem given the following code:
def get_host_view(client) : 
    'Return an IPython parallel direct view with one engine per host.' 
    all_engines = all_engines [:] 
    @ interactive 
    def hostname() : 
        import socket 
        return socket.gethostname () 
hostnames = all_engines.apply (hostname).get_dict () 
    one_engine_per_host = dict (((hostname, engine_id) for (engine_id, hostname) in hostnames.items ())) 
    return client [one_engine_per_host.values ()] 

    
    

    Fix the buggy line: all_engines = all_engines [:]
assistant
#Here is Python program to fix the buggy line: all_engines = all_engines [:]
.

all_engines = client [:]
