This tutorial discusses the
codecs.open() function in Python.
codecs.open() function works in parallel with the in-built
open() function in Python and opens up files with a specific encoding. By default, it opens a file in the read mode.
codecs.open() function opens all files in binary mode, even if it isn’t manually mentioned in the syntax of the code. This avoids data loss that may occur when dealing with 8-bit encoding.
The syntax for the
codecs.open() function is as follows:
codecs.open(filename, mode='r', encoding=None, errors='strict', buffering=- 1)
The arguments in the syntax of the function depicted above contain their default values.
codecs.open() function became obsolete after version 2.6 of Python was released. Python added another
io.open() function that was utilized to enhance the in-built
open() function’s capabilities.
The syntax of the
io.open() function, which is mostly compared to the
codecs.open() function, is relatively different from the
codecs.open() function, which is as follows.
io.open(file, mode='r', buffering=-1, encoding=None, errors=None, newline=None, closefd=True, opener=None)
codecs.open() function, although still existing in the newer versions, has no real value and is mostly utilized for backward compatibility.
