2. The Very High Level Layer

The functions in this chapter will let you execute Python source code given in a file or a buffer, but they will not let you interact in a more detailed way with the interpreter.

int PyRun_AnyFile (FILE *fp, char *filename)

If fp refers to a file associated with an interactive device (console or terminal input or Unix pseudo-terminal), return the value of PyRun_InteractiveLoop(), otherwise return the result of PyRun_SimpleFile(). If filename is NULL, use "???" as the filename.

int PyRun_SimpleString (char *command)

Executes the Python source code from command in the __main__ module. If __main__ does not already exist, it is created. Returns 0 on success or -1 if an exception was raised. If there was an error, there is no way to get the exception information.

int PyRun_SimpleFile (FILE *fp, char *filename)

Similar to PyRun_SimpleString(), but the Python source code is read from fp instead of an in-memory string. filename should be the name of the file.

int PyRun_InteractiveOne (FILE *fp, char *filename)

int PyRun_InteractiveLoop (FILE *fp, char *filename)

struct _node* PyParser_SimpleParseString (char *str, int start)

Parse Python source code from str using the start token start. The result can be used to create a code object which can be evaluated efficiently. This is useful if a code fragment must be evaluated many times.

struct _node* PyParser_SimpleParseFile (FILE *fp, char *filename, int start)

Similar to PyParser_SimpleParseString(), but the Python source code is read from fp instead of an in-memory string. filename should be the name of the file.

PyObject* PyRun_String (char *str, int start, PyObject *globals, PyObject *locals)

Execute Python source code from str in the context specified by the dictionaries globals and locals. The parameter start specifies the start token that should be used to parse the source code.

Returns the result of executing the code as a Python object, or NULL if an exception was raised.

PyObject* PyRun_File (FILE *fp, char *filename, int start, PyObject *globals, PyObject *locals)

Similar to PyRun_String(), but the Python source code is read from fp instead of an in-memory string. filename should be the name of the file.

PyObject* Py_CompileString (char *str, char *filename, int start)

Parse and compile the Python source code in str, returning the resulting code object. The start token is given by start; this can be used to constrain the code which can be compiled. The filename specified by filename is used to construct the code object and may appear in tracebacks or SyntaxError exception messages. This returns NULL if the code cannot be parsed or compiled.
