I'm trying to learn how to use `manim`. I've been looking at what I believe is the standard [tutorial](https://talkingphysics.wordpress.com/2019/01/08/getting-started-animating-with-manim-and-python-3-7/). I'm now taking some code from the [documentation](https://manim.readthedocs.io/en/latest/getting_started/learning_by_example.html) of manim (not the tutorial).

The code I'm running is this (taken from the first example, but with the import command added):

```
from manimlib.imports import *

class SquareToCircle(Scene):
    def construct(self):
        circle = Circle()
        square = Square()
        square.flip(RIGHT)
        square.rotate(-3 * TAU / 8)
        circle.set_fill(PINK, opacity=0.5)

        self.play(ShowCreation(square))
        self.play(Transform(square, circle))
        self.play(FadeOut(square))

```

and I'm running it from the command line

When I select 25, it runs and produces the output expected. But where are all of those other options coming from? Is there a way to avoid having them show up?
