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!
Ответ:
Это тоже самое, что и if, только сначало проверяется, выполняется ли if, а затем уже, если if не выполняется, происходит проверка elif.
Объяснение:
Пример.
a = 10
if a < 6:
print(‘1’)
elif a < 11:
print(‘2’)
Сначало проверится, 10 < 6? Нет, значит смотрим на другое условие. 10 < 11? Да, значит выполнится print(‘2’)
Ещё пример.
a = 5
if a < 10:
print(‘1’)
elif a < 15:
print(‘2’)
Выполнится print(‘1’), т.к. сначала идёт проверка, 5 < 10? Да, значит выполняется print(‘1’) и elif уже не проверяется.
