Static Methods
File (Constructor)
File(filein, mode='r', buffering=-1, encoding=None, errors=None, newline=None, closefd=True)
Constructor
It checks for unimplemented parameters.
- filein
-
filename or file descriptor (string)
- mode=

access mode (string)
- buffering=
-
size of the read buffer (string)
- encoding=

character encoding for reading/ writing (string)
- errors=
-
behavior for the character encoding ('strict',
'explicit', ...) (string)
- newline=
-
controls how universal newlines works (string)
- closefd=
-
close underlying file descriptor if given as file
parameter (boolean)
- Raises NotImplementedError:
-
for not implemented method parameters
