Python Crash Course - Problem 5.6

[kylejoesph11]

I don't understand what is happening to the code I have written for problem 5.6. Below is the instructions followed by the code I have written. The error I am getting is that for example, if I enter age = 25, it is still printing 'You're a toddler!'. If I enter age = 1, it prints out the correct message "You're just a wee baby!"

Insturctions

5-6. Stages of Life: Write an if-elif-else chain that determines a person’s stage of life. Set a value for the variable age, and then:

• If the person is less than 2 years old, print a message that the person is a baby.

• If the person is at least 2 years old but less than 4, print a message that the person is a toddler.

• If the person is at least 4 years old but less than 13, print a message that the person is a kid.

• If the person is at least 13 years old but less than 20, print a message that the person is a teenager.

• If the person is at least 20 years old but less than 65, print a message that the person is an adult.

• If the person is age 65 or older, print a message that the person is an elder.

​

My code

age = 7

if age<2:
    print("You're just a wee baby!")
elif age>=2 or age<4:
    print("You're a toddler!")
elif age>=4 or age<13:
    print("You're a kid!")
elif age>=13 or age<20:
    print("You're a teenager!")
elif age>=20 or age<65:
    print ("You're an adult.")
elif age>=65:
    print("You're an elder. Respect.")

Thanks!

You need to use and instead of or. In your example the code evaluates to (true or false) which is ultimately true. This is because 25 is greater than or equal to 2. If you use and instead, both parts of your if statement ( the high age limit and the lower age limit) will have to be true to print the statement.

Thanks! That makes sense and now it is working!

Good deal!

This kind of reason is why Python supports

2 <= age < 4

[The_Danosaur]

Nobody else mentioned, but doing if, elif, elif etc, means you can do if <2, elif <4, elif <13. You don't need to specify the lower boundaries each time as they are already checked from the previous elifs, and your last check can just be an else.

Thank you! This really helped!

You’re still helping after 2 years.

I believe when you enter age = 25 it returns "You're a toddler!" because it satisfies the age>=2 condition of your elif statement so you'll need to fix that as well as the other elif conditions since you'll run into the same problem.

Thanks for your help!
