Tell us what’s happening:

I’m driving myself crazy… Re-readed everything, over and over and still can’t find what’s wrong. I’m starting and ending each line with the new line character. Help, please!

Your code so far

import math

GRAVITATIONAL_ACCELERATION = 9.81
PROJECTILE = "∙"
x_axis_tick = "T"
y_axis_tick = "⊣"

class Projectile:
    __slots__ = ('__speed', '__height', '__angle')

    def __init__(self, speed, height, angle):
        self.__speed = speed
        self.__height = height
        self.__angle = math.radians(angle)


    def __calculate_displacement(self):
        horizontal_component = self.__speed * math.cos(self.__angle)
        vertical_component = self.__speed * math.sin(self.__angle)
        squared_component = vertical_component**2
        gh_component = 2 * GRAVITATIONAL_ACCELERATION * self.__height
        sqrt_component = math.sqrt(squared_component + gh_component)
        
        return horizontal_component * (vertical_component + sqrt_component) / GRAVITATIONAL_ACCELERATION

    def __str__(self):

ball = Projectile(10, 3, 45)
print(ball)

The character that you’ve used for degrees symbol is incorrect: º
It has a little line under it, it’s the Ordinal indicator
https://en.wikipedia.org/wiki/Ordinal_indicator

You can copy the correct one from the code example
