Hi, I am looking for the implementation of open() in the src, but so far I am not able to do this.
In Python 3, builtins.open is the same as io.open, which is implemented in the _io_open function in Modules/_io/_iomodule.c.
From my observation, the implementation of open() in python2/3 does not employ the open(2) system call. However without open(2) how can one possibly obtain a file descriptor? There is a call to open() (the C function) in _io_FileIO___init___impl in Modules/_io/fileio.c. I haven't traced through all the code, but I suspect builtins.open ends up calling that.
