Tell us what’s happening:

What exactly is wrong here. I’m getting Projectile(45, 45, 45) should be correct. I have checked this issue on the forum and confirmed the spacing and spelling is correct. I also made it as one string. I really don’t get where I am going wrong.

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):   
        m = (f'\n  Projectile details: \n  speed: {self.__speed} m/s \n  height: {self.__height} m \n  angle: {int(math.degrees(self.__angle))}° \n  displacement: {round(self.__calculate_displacement(), 1)} m \n')
        return m
ball = Projectile(10, 3, 45)
print(ball)

you have extra spaces at the beginning and end of each line

Thanks, seen and done
