Passing python lists/tuples as arguments in custom command

[space9]

I'd like to be able to create a command that will accept from python a large list, or even better a list of tuples, as an argument.   Just like the curve command for instance:  cmds.curve( d=1, p= [ (x,y,z), (x,y,z), (x,y,z), ... ] )  And then translate it into a multidimensional array.

I can use the addFlag and flagArgument functions to pass data through, but the data types seem limited.

Here is what I have:

MSyntax CreateMesh::newSyntax()
{
    MSyntax syntax;
 
    syntax.addFlag( "-arg", "-argument", MSyntax::kDouble);
 
    return syntax;
}
 
MStatus CreateMesh::doIt(const MArgList &argList)
{
    MStatus status;
 
    MArgDatabase argData(syntax(), argList, &status );
    CHECK_MSTATUS_AND_RETURN_IT(status);
 
    double arg1, arg2;
    arg1 = argData.flagArgumentDouble("-arg", 0);
}

Found a solution in case anyone was wondering:

MSyntax CreateMesh::newSyntax()
{
    MSyntax syntax;
 
    syntax.addFlag( "-arg", "-argument", MSyntax::kDouble, MSyntax::kDouble, MSyntax::kDouble );
    syntax.makeFlagMultiUse("-arg");
 
    return syntax;
}
 
MStatus CreateMesh::doIt(const MArgList &argList)
{
 
    MStatus status;
 
    MArgDatabase argData(syntax(), argList, &status );
    CHECK_MSTATUS_AND_RETURN_IT(status);
 
    uint numUses = argData.numberOfFlagUses("-arg");
    for( uint use = 0; use < numUses; use++ )
    {
        MArgList argList;
        status = argData.getFlagArgumentList( "-arg", use, argList );
        if( !status ) return status;
 
        double d1 = argList.asDouble( 0, &status );
        double d2 = argList.asDouble( 1, &status );
        double d3 = argList.asDouble( 2, &status );
 
        if( !status ) return status;
 
        MGlobal::displayInfo(MString()+d1+", "+d2+", "+d3);
    }
 
}

Thanks! this was a really useful hint.
