 This tutorial uses Python 3. Python 2 is getting outdated all the time,
 and more and more projects are moving to Python 3. There are a few
 popular libraries that don't support Python 3 that well at the time of

 ### Using if statements
 
-Back in chapter 2, we learned what the boolean values True and False are.
+Now we know what True and False are.
 
 ```py
 >>> 1 == 1
 True
 >>> 1 == 2
 False
 >>>
-```
-
-We also learned how to assign them to variables.
-
-```py
 >>> its_raining = True
 >>> its_raining
 True
 >>>
 ```
 
-But what if we want to execute different code depending on something? That's when `if` comes in.

+The prompt changed from `>>>` to `...`. It meant that Python was
+expecting me to keep typing. When I was done, I just pressed Enter
+twice. My code was execute and the prompt was restored to `>>>`.

+At this point it's easier to put your code into a file and use it
+there. If you use IDLE, go to File at top left and select New File, or
+just press Ctrl+N.

-After typing the line with print we need to press Enter twice to actually run the code we wrote. IDLE also indents everything we want to run if it's raining.
