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!
Відповідь:
def same(*args):
return len(set(args)) == 1
Пояснення:
*args в функции — это необязательный аргумент, который позволяет передавать произвольное количество позиционных аргументов в виде кортежа.
set(args) создает множество из переданных аргументов, которое автоматически уберет все дубликаты.
len(set(args)) даст количество уникальных аргументов, а если оно равно 1, то все аргументы были одинаковые, и функция вернет True, иначе — False.

>>> same(1, 1, 1)
True
>>> same(1, 2, 1)
False
>>> same(5)
