Python for ios interpreter [duplicate]

Answer 1

I am the sole creator of Python for iOS so that is of course what I would recommend, but a good indicator for your personal decision is the reviews & ratings of each App. It took me weeks to figure out how to properly integrate python into Objective-c for this App but here is the best resource to get you started (keep in mind that ObjC is just a superset of C):

http://docs.python.org/c-api/

Also, here is an example of calling a function defined in myModule. The equivient python would be:

import myModule
pValue = myModule.doSomething()
print pValue

In Objective-c:

#include 

- (void)example {

    PyObject *pName, *pModule, *pDict, *pFunc, *pArgs, *pValue;
    NSString *nsString;

    // Initialize the Python Interpreter
    Py_Initialize();

    // Build the name object
    pName = PyString_FromString("myModule");

    // Load the module object
    pModule = PyImport_Import(pName);

    // pDict is a borrowed reference 
    pDict = PyModule_GetDict(pModule);

    // pFunc is also a borrowed reference 
    pFunc = PyDict_GetItemString(pDict, "doSomething");

    if (PyCallable_Check(pFunc)) {
        pValue = PyObject_CallObject(pFunc, NULL);
        if (pValue != NULL) {
            if (PyObject_IsInstance(pValue, (PyObject *)&PyUnicode_Type)) {
                    nsString = [NSString stringWithCharacters:((PyUnicodeObject *)pValue)->str length:((PyUnicodeObject *) pValue)->length];
            } else if (PyObject_IsInstance(pValue, (PyObject *)&PyBytes_Type)) {
                    nsString = [NSString stringWithUTF8String:((PyBytesObject *)pValue)->ob_sval];
            } else {
                    /* Handle a return value that is neither a PyUnicode_Type nor a PyBytes_Type */
            }
            Py_XDECREF(pValue);
        } else {
            PyErr_Print();
        }
    } else {
        PyErr_Print();
    }

    // Clean up
    Py_XDECREF(pModule);
    Py_XDECREF(pName);

    // Finish the Python Interpreter
    Py_Finalize();

    NSLog(@"%@", nsString);
}
