Help please! I'm asked to write a python program to calculate the trajectory of a projectile. I've started writing the program but I'm stuck at the plotting part. I don't know how to store the trajectory points and plot them on graph.

The answer to that depends o a lot of things.  Are you using one of the math packages to do this and does it have a plotting part built in?  Are you using a graphics package?  So on and so forth.  If you are just using Python itself, that may be the issue.  Without a library to do the work, you will have to start from scratch and that is a big deal.  You may want a basic graphics or computational library that has plotting built in.  Then you just need to store you data in a way that is appropriate for feeding to that that package.

On a basic level you could create two arrays, xArray and yArray, of a length equal to the number of points you're interested in using. Once you populate your arrays you will have a collection of ordered pairs that you can call at will.
