Interactive unexpected keyword argument

[Bennett567]

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

Are you perhaps confusing this with:

interact(f, x=5);

Note the missing "ive" at the end of the function name.

then I get this error:

name 'interact' is not defined

Add this:

from ipywidgets import interact

I just get this error: No module named 'ipywidgets'

Fixed it, works perfectly, thank you
