        self.play(Write(texto))
        self.wait()

Scene with text and animation

from manim import *

class MiEscena(Scene):
    def construct(self):
        texto = Text("Hola mundo")
        self.play(Write(texto))
        self.wait()
        self.play(texto.animate.shift(UP))

        grafica = Axes(
            x_range=[-2, 2, 1],
            y_range=[-2, 2, 1],
            x_length=6,
            y_length=6,
            axis_config={"include_tip": True},
        )
        grafica.add_coordinate_labels()
        funcion = grafica.get_graph(lambda x: np.sin(x), color=BLUE)
