OK, But you will need to give us some more details.

Which beginner's guide are you using?
Plotting is not something normally covered in a Python beginner's
guide - it's not part of standard Python, you usually need some
extra modules to do that.

Which plotting module are you using?
Or are you trying to do it using a GUI toolkit (if so which one?)?

Normally you would generate a set of data pairs and then plot those.
Do you know how to create a list of values based on your input 'a' values?

for example if I wanted to plot the first 10 integer squares
I'd generate a list of values something like:

data = [(n,n**n) for n in range(10)]

That would give me a data list that looked like:

[(0,0),(1,1),(2,4),(3,9),...(9,81)]

I could then plot each pair on a graph or chart of some sort.
