Write a program that lets you know if you can have a key or not, based on your role at the school.
First ask for the user’s role at the school. They can be a student, administrator, or a teacher. (And remember that capitalization is important! ‘Student’ is not the same as ‘student’.)
Example 1: Administrator or Teacher
For example, if this was the input:
Are you an administrator, teacher, or student?: teacher
This should be the output:
Administrators and teachers get keys!
Example 2: Student
And if this was the input:
Are you an administrator, teacher, or student?: student
This should be the output:
Students do not get keys!
(Note: You should also be able to handle a situation where the user enters a value other than administrator, teacher or student and tell them they must be one of the three choices!)
Example 3: Other
If they input anything else:
Are you an administrator, teacher, or student?: secretary
This should be the output:
You can only be an administrator, teacher, or student!

Для решения данной задачи на языке Python ( сделал на питоне) можно использовать цикл for и встроенную функцию round() для округления значений координат. Вот пример кода:
# задаем функцию y = 3 — x^2 + 1.5
def f(x):
return 3 — x**2 + 1.5
# задаем начальное и конечное значение х, а также шаг
x_start = -5
x_end = 5
step = 0.5
# создаем пустой список для хранения координат
coordinates = []
# запускаем цикл для вычисления координат
for x in [i/2 for i in range(-10, 11)]:
y = f(x)
coordinates.append((round(x, 2), round(y, 2)))
# выводим результат
print(«xty»)
for coord in coordinates:
print(coord[0], «t», coord[1])
Результат выполнения программы будет выглядеть следующим образом:
x y
