Now that you know what the dynamically typed programming language is, let's see what basic data types

we have in Python.

The type will be associated with the value stored in the variable at runtime.

Will quickly discuss the main python data types and then our focus will go into more detail about each

of them.

These are all the python built in data types.

Numbers which are integers or whole numbers in the floating point numbers, or simply floats booleans,

which represent logical values indicating a true or false.

In Python there are two boolean constants defined.

True.

Always written with uppercase D and false.

Written with uppercase F.

Most of the time, booleans are used to test different conditions.

Let's see an example.

Age equals 40 and the name equals then.

And I'm printing.

X equals equals 40.

This statement will return a boolean value.

It returned true or print x greater than 20.

It returned true as well.

Or print name.

Equals equals.

Andre.

This statement will return false.

And this one print lane of name.

Not equals ten.

I am testing if the length of the name variable is not equal to ten and it will return true.

Note that in Python there is also another constant called none.

This is frequently used to represent the absence of a value as when some arguments are not passed to

a function, or when a function does not return something explicitly and returns none.

Let's move to the next data type strings.

Are ordered sequences of characters encoded using UTF eight.

Lists are ordered mutable sequences of objects.

To create a list, use the name of the list equals and the pair of square brackets and the square brackets.

The elements of the list separated with commas.

A list can contain any type of elements, a string.

An integer.

A float.

A boolean value.

Or another list.

Another datatype is the table.

Toppers are ordered immutable sequences of objects.

By the way, an object whose internal state can be changed is mutable.

On the other hand, immutability doesn't allow any change in the object once it has been created.

Let's move on.

Sex are mutable collections of unordered unique objects.

And there are also frozen sex which are immutable collections of unordered unique objects.

And finally, dictionaries are collections of unordered key value pairs.

We've seen the main data types of Python core programming language.

In the next lectures, we'll take a closer look at each of them and discuss them in depth.
