Use type() to find out what type a value or variable is:
print(type(42)) # <class 'int'>
print(type(3.14)) # <class 'float'>
print(type("hello")) # <class 'str'>
print(type(True)) # <class 'bool'>
This is useful for debugging. If your code isn't working, checking types often reveals the problem. Maybe you thought a variable was a number, but it's a string.
The output shows <class 'int'> instead of just int. That's Python telling you integers are a class. Don't worry about classes for now. Just read the type name.
