We are going to learn a new loop, the `{while}` loop! We continue the loop as long as the statement is true.
So don't forget to change the value in the loop.

In the example code, we continue until a correct answer has been given.
If the correct answer is never given, the loop never ends!In this game below a code has been made to make sure the player can play on as long as they want...
But the code is ineffective and way too long. Also, what if the player wants to play 101 games instead of 100?
You can't play to infinity?
In this level you will learn a command that makes all of this a lot easier!

In the previous levels you've learned how to put two `{if}`commands inside each other. This works fine, but it does give you very long and unhandy codes like this one:

In this system you have to give both the correct username and the correct password.
In this level you will learn the `{and}` command that will make this code a lot shorter and more understandable!
Check it out!
We are now going to learn `{and}` and `{or}`! If you want to check two statements, you don't have to use two {if}'s but can use `{and}` and `{or}`. If you use `{and}`, both statements, left and right of the `{and}` need to be true. We can also use `{or}`. Then only one statement needs to be correct.
adventures->default->levels->13->example_code
```
username = {ask} 'What is your username?'
password = {ask} 'What is your password?'
{if} username {is} 'Hedy'
{if} password {is} 'secret'
{print} 'Welcome Hedy!'
{else}
{print} 'Access denied'
{else}
{print} 'Access denied!'
```
```
name = {ask} 'what is your name?'
age = {ask} 'what is your age?'
{if} name {is} 'Hedy' {and} age {is} 2
{print} 'You are the real Hedy!'
```

With the example code you can calculate if you've passed a subject at school (so, a grade of six or higher).
You can see this code is extremely inefficient, due to the very long code in line 5.
All the different grades from 1 to 5 had to be programmed separately. Lucky for you, in this level you'll learn how to do this without this extremely long code!
We are going to learn more new items. You might know them already from mathematics, the `<` and `>`.
The `<` checks if the first number is smaller than the second, for example age `<` 12 checks if age is smaller than 12.
If you want to check if the first number is smaller or equal to the second, you can use `<=`, for example age `<=` 11.
The `>` checks if the first number is bigger than the second, for example points `>` 10 checks if points is larger than 10.
If you want to check if the first number is bigger or equal to the second, you can use `>=`, for example points `>=` 11.
You use these comparisons in an `{if}`, like this:
adventures->default->levels->14->example_code
```
first_grade = {ask} 'What score did you get on your first test?'
second_grade = {ask} 'What score did you get on your second test?'
added = first_grade + second_grade
mean_grade = added / 2
{if} mean_grade = 1 {or} mean_grade = 2 {or} mean_grade = 3 {or} mean_grade = 4 {or} mean_grade = 5
{print} 'Oh no! You have failed the subject...'
{else}
{print} 'Great! You have passed the subject!'
```
```
age = {ask} 'How old are you?'
{if} age > 12
{print} 'You are older than I am!'
```

{if} age < 13
{print} 'You are younger than me!'
{else}
{print} 'You are older than me!'

In this level we will grow a bit more towards real Python code. You will also learn how to match two lists together.
This way you can program a code in which the correct animal is matched to the right sound.
Because the two codes below... Are obviously nonsense!
We are going to make lists the Python way, with square brackets around the lists! We also keep the quotation marks around each item like we have learned in previous levels.
You can use the square brackets as well to point out a place in the lists.
adventures->default->levels->16->example_code
```
animals = 'chicken', 'horse', 'cow'
sounds = 'cluck', 'neigh', 'moo'
{for} animal {in} animals
{print} 'A ' animal ' says ' sounds {at} {random}
```
You could also try to make it work this way, but....
```
animals = 'chicken', 'horse', 'cow'
sounds = 'cluck', 'neigh', 'moo'
{for} animal {in} animals
{for} sound {in} sounds
{print} 'A ' animal ' says ' sound
```
Note: These codes will not work like this in this level. Head to the next tab to see which parts you need to correct.
```
friends = ['Ahmed', 'Ben', 'Cayden']
{print} friends[1] ' is the first friend on the list.'
{print} friends[2] ' is the second friend on the list.'
{print} friends[3] ' is the third friend on the list.'
#now we will match 2 lists using the variable i
lucky_numbers = [15, 18, 6]
{for} i {in} {range} 1 {to} 3
{print} friends[i] 's lucky number is ' lucky_numbers[i]
```

Now we are going to change indentation a little bit. Every time that we need an indentation, we need `:` at the line before the indentation.

In this level you can also use a new command: `{elif}`. `{elif}` is short for ``{else} {if}`` and you need it when you want to make 3 (or more!) options.
Check it out!

Congratulations! You have reached the last level of Hedy! The code you have created here can be copied to real Python environments like replit or PyCharm, and you can continue learning there!
Note however that Python can only read English commands, so if you have been using other languages, you will need to switch to English now.
We arrived at real Python code! That means we need to use parentheses with {print} and {range} from now on.
{print}('My name is ', name)
