0 and 1 are ints:

just like 2, 3, 4, -1, -999, 1098765432 etc.
But just like 1 == 1.0 (a fl

So for example for "bool" , it only applies to True/False and nothing else? (2
data types), i.e. :
Not exactly... bool is the data type (or class), True and False are the only two _values_ (not
types).
type(True)
type(False)

No types but any variable or expression containing True or False will be
a bool type (or class bool):
A = 10<20
print (type(A)) =>
print (10<20

Correct. True and False are the only instances of the type 'bool'.

I am new to python and learning it. Can you please give me a simple

Lists, tuples, and dictionaries are built-in types.
Classes are the mechanism for user-defined types in Python.
