Définition

class FileIO(_RawIOBase):

help(FileIO)

Open a file.

The mode can be 'r' (default), 'w', 'x' or 'a' for reading,
writing, exclusive creation or appending.  The file will be created if it
doesn't exist when opened for writing or appending; it will be truncated
when opened for writing.  A FileExistsError will be raised if it already
exists when opened for creating. Opening a file for creating implies
writing so this mode behaves in a similar way to 'w'.Add a '+' to the mode
to allow simultaneous reading and writing. A custom opener can be used by
passing a callable as *opener*. The underlying file descriptor for the file
object is then obtained by calling opener with (*name*, *flags*).
*opener* must return an open file descriptor (passing os.open as *opener*
results in functionality similar to passing None).
