Sometimes we want to ask Python, “What kind of thing is this?”
Python has a helper called type() that tells us what kind of data something is.
All you need to do is put your value inside type(), like this: type(5).
To see the answer on the screen, we use print() in front of it.
So we write: print(type(5)).
This shows that 5 is a whole number.
print(type(3.14)) shows that 3.14 is a decimal number.
print(type("Hello")) shows that "Hello" is text (words).
A string is text in Python, written inside quotes.
Strings must always be inside quotes " " in Python.
Each line checks one value and prints what type it is.
This helps us understand what kind of data our program is using.
