I want to make a discount of 31% to all users under 25 years and 50% to users over 40 years. 

On the other side to users who do not live in Madrid only a discount of 5%.

```
students = [
    ('Marcos', 23, 'Madrid', 850, '2388711341'),
    ('Elena', 35, 'Madrid', 360, '0387700342'),
    ('Carmen', 21, 'Getafe', 50, '0014871388'),
    ('Carlos', 41, 'Madrid', 580, '00887118456'),
    ('Maria', 28, 'Madrid', 150, '587')
]

for item in students:
    student, age, city, debt, id = item
if age < 25
    else debt * 0.69
if age > 40
    else debt * 0.5
if city is not 'Madrid'
    else debt * 0.95
    print(f'Name: {student} - Debt: {debt}')

```

Print Example:
Name: Marcos - Debt: 586,5

Name: Elena - Debt: 360

Name: Carmen - Debt: 47,5

Name: Carlos - Debt: 290

Name: Maria - Debt: 150
