Instances of this class shouldn't be created manually, use `dbf.Dbf.newRecord` instead. Class implements mapping/sequence interface, so fields could be accessed via their names or indexes (names is a preferred way to access fields). Hint: Use `store` method to save modified record. Examples: Add new record to the database: db = Dbf(filename) rec = db.newRecord() rec["FIELD1"] = value1 rec["FIELD2"] = value2 rec.store() Or the same, but modify existed (second in this case) record: db = Dbf(filename) rec = db[2] rec["FIELD1"] = value1 rec["FIELD2"] = value2 rec.store() )dbfindexdeleted fieldDataNc||_||_||_|4|jjDcgc]}|j c}|_yt||_ycc}w)a$Instance initialization. Arguments: dbf: A `Dbf.Dbf` instance this record belongs to. index: An integer record index or None. If this value is None, record will be appended to the DBF. deleted: Boolean flag indicating whether this record is a deleted record. data: A sequence or None. This is a data of the fields. If this argument is None, default values will be used.
