Module « codecs » Python 3.13.2

Fonction open - module codecs

Signature de la fonction open

def open(filename, mode='r', encoding=None, errors='strict', buffering=-1) 

Description

help(codecs.open)

Open an encoded file using the given mode and return
a wrapped version providing transparent encoding/decoding.

Note: The wrapped version will only accept the object format
defined by the codecs, i.e. Unicode objects for most builtin
codecs. Output is also codec dependent and will usually be
Unicode as well.

If encoding is not None, then the
underlying encoded files are always opened in binary mode.
The default file mode is 'r', meaning to open the file in read mode.

encoding specifies the encoding which is to be used for the
file.

errors may be given to define the error handling. It defaults
to 'strict' which causes ValueErrors to be raised in case an
encoding error occurs.

buffering has the same meaning as for the builtin open() API.
It defaults to -1 which means that the default buffer size will
be used.

The returned wrapped file object provides an extra attribute
.encoding which allows querying the used encoding. This
attribute is only available if an encoding was specified as
parameter.
