Previewing manim output with option -n 0,0

[dan-whitman]

Description of bug / unexpected behavior

I am trying to set up macros on Sublime to automatically render and preview certain portions of my code. When I try to only preview the first animation of a scene using -pql -n 0,0, it renders all animations for the scene. Every other animation number I tried (-n 1,1; -n 2,2; etc.) worked as expected.

Expected behavior

I would expect -pql -n 0,0 to only preview the first animation of the scene.

How to reproduce the issue

Code for reproducing the problem

```py class SquareToCircle(Scene): def construct(self): circle = Circle() # create a circle circle.set_fill(PINK, opacity=0.5) # set the color and transparency square = Square() square.rotate(PI / 4) self.play(Create(square)) self.play(Transform(square, circle)) self.play(FadeOut(square)) ``` Running with command: manim {filepath}\{filename} SquareToCircle -pql --progress_bar none -n #,# in Windows command prompt. ## Additional media files

Thanks for the report! Indeed, this was a bug with how the flag was handled internally -- I've implemented a fix in #4013, should be fixed in the upcoming release. 👍
