Solve the following python programming problem given the following code:
def _logical(tokens) : 
    'Find how many logical lines are there in the current line.

    Normally 1 line of code is equivalent to 1 logical line of code,
    but there are cases when this is not true. For example::

        if cond: return 0

    this line actually corresponds to 2 logical lines, since it can be
    translated into::

        if cond:
            return 0

    Examples::

        if cond:  -> 1

        if cond: return 0  -> 2

        try: 1/0  -> 2

        try:  -> 1

        if cond:  # Only a comment  -> 1

        if cond: return 0  # Only a comment  -> 2
    ' 
    def aux(sub_tokens) : 
        'The actual function which does the job.' 
        processed = list (_less_tokens (sub_tokens, [COMMENT])) 
        try : 
            token_pos = _find (processed, OP, ':') 
            return (2 - (token_pos == (len (processed) - 2))) 
except ValueError : 
            if (not list (_less_tokens (processed, [NL, EM]))) : 
                return 0 
return 1 
return sum ((aux (sub) for sub in _split_tokens (sub, OP, ';'))) 

    
    

    Fix the buggy line: return sum ((aux (sub) for sub in _split_tokens (sub, OP, ';')))
assistant
#Here is Python program to find how many logical lines are there in the current line.

return sum ((aux (sub) for sub in _split_tokens (tokens, OP, ';')))
