I have a simple function which is called like this:

```
arbitrary_function(**kwargs1, **kwargs2, **kwargs3)

```

It seems to compile fine on my local installation (python 3.5.1) but throws a SyntaxError when I compile it on a docker with python 3.4.5.

I'm not too sure why this behavior is present. Are multiple kwargs not allowed? Should I combine them before passing to function? It is more convenient to pass them individually, for example:

```
plot(**x_axis_params, **y_axis_params, **plot_params)

```

instead of 

```
params = dict()

for specific_param in [x_axis_params, y_axis_params, plot_params]:    
    params.update(specific_param)

plot(**params)

```
