Graviton Graviton Some comments: I have seen some people use mapping to solve this problem, but really, is there no built-in conversion that does this kind of ANSI to unicode and vice versa conversion? On reading, the escapechar removes any special meaning from the following character.
It defaults to None , which disables escaping. The string used to terminate lines produced by the writer. This behavior may change in the future. A one-character string used to quote fields containing special characters, such as the delimiter or quotechar , or which contain new-line characters. It defaults to '"'. Controls when quotes should be generated by the writer and recognised by the reader. When True , whitespace immediately following the delimiter is ignored.
The default is False. Reader objects DictReader instances and objects returned by the reader function have the following public methods:. Usually you should call this as next reader. The number of lines read from the source iterator. This is not the same as the number of records returned, as records can span multiple lines. If not passed as a parameter when creating the object, this attribute is initialized upon first access or when the first record is read from the file.
Writer objects DictWriter instances and objects returned by the writer function have the following public methods. A row must be an iterable of strings or numbers for Writer objects and a dictionary mapping fieldnames to strings or numbers by passing them through str first for DictWriter objects.
Note that complex numbers are written out surrounded by parens. This may cause some problems for other programs which read CSV files assuming they support complex numbers at all. Return the return value of the call to the write method of the underlying file object. Return the return value of the csvwriter.
Since open is used to open a CSV file for reading, the file will by default be decoded into unicode using the system default encoding see locale. To decode a file using a different encoding, use the encoding argument of open:. The same applies to writing in something other than the system default encoding: specify the encoding argument when opening the output file. Navigation index modules next previous Python ».
DictReader csvfile Note This method is a rough heuristic and may produce both false positives and negatives. Dialects support the following attributes: Dialect. Reader objects have the following public attributes: csvreader. In particular, some APIs that accept both bytes and text may be very strict about the encoding of the bytes they accept for example, the urllib. This section explores a number of use cases that can arise when processing text.
All files must be processed without triggering any exceptions, but some risk of data corruption is deemed acceptable e. This is the closest equivalent Python 3 offers to the permissive Python 2 text handling model.
All files must be processed without triggering any exceptions, but some Unicode related errors are acceptable in order to reduce the risk of data corruption e. Approach: use the ascii encoding with the surrogateescape error handler. Use case: the files to be processed are in a consistent encoding, the encoding can be determined from the OS details and locale settings and it is acceptable to refuse to process files that are not properly encoded.
Approach: simply open the file in text mode. This use case describes the default behaviour in Python 3. Popular Examples Add two numbers. Check prime number. Find the factorial of a number.
