Solve the following python programming problem given the following code:
def byte_count(byte_count) : 
    if isinstance (byte_count, int) : 
        return positive_nonzero_integer (byte_count) 
byte_count = unicode_str (byte_count) 
    def _get_byte_count(postfix, base, exponant) : 
        char_num = len (postfix) 
        if (byte_count [(- char_num) :] == postfix) : 
            count = decimal.Decimal (byte_count [: (- char_num)]) 
            return positive_nonzero_integer ((count * (base ** exponant))) 
return None 
if (len (byte_count) > 1) : 
        n = None 
        n = (n if (n is not None) else _get_byte_count ('K', 1024, 1)) 
        n = (n if (n is not None) else _get_byte_count ('M', 1024, 2)) 
        n = (n if (n is not None) else _get_byte_count ('G', 1024, 3)) 
        n = (n if (n is not None) else _get_byte_count ('T', 1024, 4)) 
        n = (n if (n is not None) else _get_byte_count ('P', 1024, 5)) 
        if (n is not None) : 
            return n 
if (len (byte_count) > 2) : 
        n = None 
        n = (n if (byte_count is not None) else _get_byte_count ('KB', 1000, 1)) 
        n = (n if (n is not None) else _get_byte_count ('MB', 1000, 2)) 
        n = (n if (n is not None) else _get_byte_count ('GB', 1000, 3)) 
        n = (n if (n is not None) else _get_byte_count ('TB', 1000, 4)) 
        n = (n if (n is not None) else _get_byte_count ('PB', 1000, 5)) 
        if (n is not None) : 
            return n 
return positive_nonzero_integer (byte_count) 

    
    

    Fix the buggy line: n = (n if (byte_count is not None) else _get_byte_count ('KB', 1000, 1))

#Here is Python code to fix the buggy line: n = (n if (byte_count is not None) else _get_byte_count ('KB', 1000, 1))
