I've got and a boon to computer here I'm going to start Python 3.
What type is true.
Be careful when I press enter here.
What's gonna happen.
Notice I get an error.
True is not defined what type however is true.
Written like that.
Notice it's a Boolean true or false.
What type is false.
Notice error but change that to uppercase.
It's a boolean.
So as an example is one equal to one.
That's true.
Is one equal to two.
No that's false.
Is one equal to two minus one.
That's true.
Billions allow us to determine if something is true or false and then do something accordingly.
So as an example I'm in England at the moment a boolean that I would use is.
Is it raining outside.
True.
Take a umbrella.
False.
Don't take an umbrella.
Well in England you probably want to take it with you.
But on a day like today it's sunny.
No rain is predicted so I don't need an umbrella.
It's false.
