Redirecting embedded Python’s I/O

Posted on 2012-4-13 by mvasilkov
When using Python for application scripting, more often than not you want to redirect interpreter’s input/output to the embedding program. This is how it’s done with the Python/C API:

PyObject *sys = PyImport_ImportModule("sys");
PyObject *out = PyFile_FromString("python_out", "w+");
PyObject_SetAttrString(sys, "stdout", out);
Pretty intuitive, right? Now embedded Python’s stdout points to the newly created file, python_out. Working with the script’s output from C is also trivial:
