Prefer builtin open() over io.open() and codecs.open()
In Python3, the functions io.open() is an alias of the builtin open() and codecs.open() is functionally equivalent. To reduce indirection, number of imports, and number of patterns, always prefer the builtin. https://docs.python.org/3/library/io.html#high-level-module-interface > io.open() > > This is an alias for the builtin open() function.
