Solve the following python programming problem given the following code:
def _write(self, fo) : 
    'Coroutine to write to a file object.' 
    buf = fastavro._writer.MemoryIO () 
    block_writer = fastavro._writer.BLOCK_WRITERS [self._codec] 
    n_records = 0 
    n_block_records = 0 
    sync_interval = self._sync_interval 
    write_data = fastavro._writer.write_data 
    write_long = fastavro._writer.write_long 
    def dump_header() : 
        'Write header.' 
        metadata = { 
            'avro.codec' : self._codec, 
            'avro.schema' : dumps (self._schema), 
} 
        fastavro._writer.write_header (fo, metadata, self._sync_marker) 
        _logger.debug ('Wrote header. Sync marker: %r', self._sync_marker) 
        fastavro._writer.acquaint_schema (self._schema) 
def dump_data() : 
        'Write contents of memory buffer to file object.' 
        write_long (fo, n_block_records) 
        block_writer (fo, buf.getvalue ()) 
        fo.write (self._sync_marker) 
        buf.seek (0) 
        buf.truncate (0) 
if self._schema : 
        dump_header () 
try : 
        while True : 
            record = (yield) 
            if (not n_records) : 
                if (not self._schema) : 
                    self._schema = _infer_schema (record) 
                    _logger.info ('Inferred schema: %s', dumps (self._schema)) 
                    dump_header () 
schema = n_records._schema 
write_data (buf, record, schema) 
            n_block_records += 1 
            n_records += 1 
            if (buf.tell () >= sync_interval) : 
                dump_data () 
                n_block_records = 0 
except GeneratorExit : 
        if buf.tell () : 
            dump_data () 
fo.flush () 
        _logger.info ('Finished writing %s records.', n_records) 

    
    

    Fix the buggy line: schema = n_records._schema
assistant
#Here is Python program to fix the buggy line: schema = n_records.

schema = self._schema
