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!

#Импортируем модуль random
import random
#Создаём массив с помощью функции choice
#Если захочешь изменить длину массива, то поменяй цифру 5 на другую
a = [random.choice([i for i in range(0, 100)]) for j in range(5)]
#Выводим содержимое массива
print(‘Массив:’,a)
#Объявляем переменные
count_1 = 0
count_2 = 0
sum_1 = 0
sum_2 = 0
#Создаём цикл для проверки условий
for i in a:
#Если переменная меньше 50, то прибавляем её к сумме
if i < 50:
sum_1 += i
count_1 += 1
#Во всех остальных случаях
else:
sum_2 += i
count_2 += 1
#Вычисляем среднее арифметическое
b = sum_1 / count_1
c = sum_2 / count_2
#Выводим среднее арифметическое элементов
print(‘nСреднее арифметическое элементов [0,50):’, b)
print(‘nСреднее арифметическое элементов [50,100):’, c)
