<h3 id="heading-data-types">Data Types</h3>
Data types define the type of values a variable can hold. Here are some common data types with simple examples:
Integers (<code>int</code>): Whole numbers without decimals.
<ul>
<li>Floats (<code>float</code>): Numbers with decimals.
</li>
<li>Strings (<code>str</code>): Text or characters enclosed in single or double quotes.
</li>
<li>Booleans (<code>bool</code>): Represents either True or False.
</li>
<li>Lists (<code>list</code>): Ordered collection of items.
</li>
<li>Tuples (<code>tuple</code>): Similar to lists but immutable (cannot be changed).
</li>
<li>Dictionaries (<code>dict</code>): Collection of key-value pairs.
</li>
<li>Sets (<code>set</code>): Unordered collection of unique items.
</li>
<li>NoneType (<code>None</code>): Represents the absence of a value or a null value.

### *Data Types*

Data types define the type of values a variable can hold. Here are some common data types with simple examples:

**Integers (**`int`**):** Whole numbers without decimals.

* **Floats (**`float`**):** Numbers with decimals.
    
* **Strings (**`str`): Text or characters enclosed in single or double quotes.
    
* **Booleans (**`bool`): Represents either True or False.
    
* **Lists (**`list`): Ordered collection of items.
    
* **Tuples (**`tuple`**):** Similar to lists but immutable (cannot be changed).
    
* **Dictionaries (**`dict`): Collection of key-value pairs.
    
* **Sets (**`set`): Unordered collection of unique items.
    
* **NoneType (**`None`): Represents the absence of a value or a null value.
