On a boon to computer I'm going to start Python 3.
What type is one two three.
That's an integer.
What type is one dot two three.
That's a floating point number.
Integers are whole numbers positive or negative.
Floating point numbers have fractions.
What type is a notice I get an error here saying that A is not defined.
But if I say that A equals hello and then specify type a notice it's a string.
If I say a plus one two three I get an error because A is a string and one two three is an integer and
they can't be added together but I could say a plus string.
One two three.
The result is Hello One two three because A's a variable contains the string hello.
And I've converted one two three to a string and then concatenated them together.
