from manimlib import *


class SquareToCircle(Scene):
    def __init__(self, **kwargs):
        super().__init__()

    def construct(self):
        circle = Circle()
        circle.set_fill(BLUE, opacity=0.5)
        circle.set_stroke(BLUE_E, width=4)
        square = Square()

        self.play(ShowCreation(square))
        self.wait()
        self.play(ReplacementTransform(square, circle))
        self.wait()

manimgl start.py SquareToCircle -ow

Why the code enter the interactive mode?
