Interactive unexpected keyword argument

Question

I am new to python, and I am working on code that displays the ball at the timestamps on a graph. I want to use interactive widget to display how the ball moves on the graph.

def f(x):
    return matplotlib.pyplot.plot(ball.posx[x],ball.posy[x],'bo', markersize=5) #displaying current 
    
interactive(f, x=5);

however, I get this error message:

interactive() got an unexpected keyword argument 'x'

But this is what it said in the documentation. How can I fix this? Thanks

added line: from ipywidgets import interact, interactive->interact
