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!

1 способ
x=int(input())
while x>0:
print(x)
x-=10
2 способ
x=int(input())
for i in range (x,0,-10):
print(i)
3 способ (немного перепишу второй, схитрю)
x=int(input())
for x in range (x,0,-10):
print(x)
Все работают.
И как обычно самый маленький однострочный вариант 4 :)
for x in range (int(input()),0,-10):print(x)
Есть только одно отличие — первый способ в лоб и в теории x может быть float. В остальных случаях только int.
Но с float тоже много интересного. Вот программа.
x=float(input())
while x>0:
print(x)
x-=10
56.6545454 — введем
На выходе получим
56.6545454
46.6545454

А потом объясняй это учителю :).
