+## Built-in Data Types
+
+In programming, a **data type** is an important concept. Variables can store data of different types, and different types can do different things.
+
+Python has the following built-in data types by default, categorized as follows:
+
+- **Text Type:** `str`
+- **Numeric Types:** `int`, `float`, `complex`
+- **Sequence Types:** `list`, `tuple`, `range`
+- **Mapping Type:** `dict`
+- **Set Types:** `set`, `frozenset`
+- **Boolean Type:** `bool`
+- **Binary Types:** `bytes`, `bytearray`, `memoryview`
+- **None Type:** `NoneType`

+## Python Data Types: List, Set, Tuple, and Dictionary
+
+### 1. List
+Lists are used to store multiple items in a single variable.List items are ordered, changeable, and allow duplicate values.
+Lists are created using square brackets []
+
+```python
+# Creating a list
+fruits = ["apple", "banana", "cherry"]
+print(type(fruits)) #Class List
+print(lent(fruits)) #2
+
+# Accessing list items
+print(fruits[0])  # Output: apple
+
+# Adding an item to the list
+fruits.append("orange")
+print(fruits)  # Output: ['apple', 'banana', 'cherry', 'orange']
+```
+
+## Here are some practice questions for Python lists:
+
+*Practice Questions*
+## Basic Operations:
+
+Create a list of your favorite fruits. Add a new fruit to the list and then remove one fruit from the list. Print the updated list.
+Write a Python program to find the length of a list without using the built-in len() function.
+
+## Accessing Elements:
+
+Given the list numbers = [10, 20, 30, 40, 50], write a Python program to access the third element.
+Write a Python program to access the last element of a list using negative indexing.
+
+## Slicing and Modifying Lists:
+
+Write a Python program to reverse a list using slicing.
+Given a list colors = ["red", "green", "blue", "yellow", "purple"], write a program to replace "blue" with "orange".
+
+## List Methods:
+
+Write a Python program to count the occurrences of a specific element in a list.
+Create a list of numbers and write a Python program to sort the list in descending order.
+
+## Comprehensions:
+
+Write a list comprehension that creates a list of the squares of all even numbers from 0 to 20.
+Given a list of strings, write a list comprehension to create a new list with only the strings that have more than 3 characters.
+
+## Nested Lists:
+
+Create a nested list (a list inside another list) and write a program to access an element from the inner list.
+Write a Python program to flatten a nested list (convert it into a single list with no nested lists).
+
+## Advanced Operations:
+
+Write a Python program to remove all occurrences of a specific value from a list without using a loop.
+Given two lists, write a Python program to merge them into a dictionary where elements from the first list are keys and elements from the second list are values.
+
+These questions cover various aspects of working with lists in Python and should provide a good range of practice.

+Sets are used to store multiple items in a single variable.
+
+A **set** is one of the 4 built-in data types in Python used to store collections of data. The other 3 are **List**, **Tuple**, and **Dictionary**, each with different qualities and usage.
+
+A **set** is a collection that is:
+- **Unordered**: The items have no defined order.
+- **Unchangeable***: The items cannot be modified after the set is created.
+- **Unindexed**: The items do not have an index.
+
+*Note: Although the items themselves cannot be changed, new items can be added or removed from the set.
+```Python
+myset={10,20,"Ali","Zain"}
+print(myste)
+print(types(set))
+
+```
+### Practice Questions for Sets
+**Basic Operations:**
+
+Create a set of your favorite colors. Add a new color to the set and then remove one color from the set. Print the updated set.
+Write a Python program to find the number of items in a set using the built-in len() function.
+
+## Set Methods:
+
+Given two sets A = {1, 2, 3, 4} and B = {3, 4, 5, 6}, write a Python program to find their union and intersection.
+Write a Python program to check if one set is a subset of another set.
+
+## Manipulating Sets:
+
+Write a Python program to remove an element from a set using the discard() method. What happens if the element does not exist in the set?
+Create two sets and write a Python program to find their symmetric difference.
+
+## Set Comprehension:
+
+Write a set comprehension that creates a set of the squares of all odd numbers from 0 to 10.
+Given a set of strings, write a set comprehension to create a new set with only the strings that start with the letter 'a'.
+
+## Advanced Operations:
+
+Write a Python program to remove all elements from a set.
+Given a set of numbers, write a Python program to find the maximum and minimum values in the set.
+
+## Using Sets to Solve Problems:
+
+Write a Python program that takes two lists and returns a set of all the elements that are present in both lists.
+Given a list of words, write a Python program to find all unique words using a set.
+
+## Converting Between Data Types:
+
+Write a Python program to convert a list to a set and then back to a list. Explain why this might be useful.
+Given a string, write a Python program to convert it into a set of characters.
