1. Python Basics:

   - Comments: # Single-line comment

2. Variables and Data Types:

   - int, float, str, bool

   - x = 5             # Variable assignment

   - type(x)           # Check variable type

3. Input and Output:

   - input("Prompt")   # User input

   - print("Text")     # Output to console

4. Conditional Statements:

   - if, elif, else

   - Comparison operators: ==, !=, <, >, <=, >=

5. Loops:

   - for, while

   - range() function

   - break, continue

6. Lists and Tuples:

   - list = [1, 2, 3]

   - tuple = (1, 2, 3)

   - Accessing elements, slicing

7. Dictionaries:

   - dict = {"key": "value"}

   - Accessing values, keys()

8. Functions:

   - def function_name(parameters):

   - return statement

   - Scope: local vs. global

9. Libraries and Modules:

   - import module_name

   - Common libraries: math, random, datetime

10. File Handling:

    - open(), read(), write(), close()

    - with open() as file:

11. Exception Handling:

    - try, except, finally

    - Handling specific exceptions

12. Object-Oriented Programming (OOP):

    - Classes and objects

    - Inheritance, encapsulation, polymorphism

13. List Comprehensions:

    - [expression for item in iterable]

14. Lambda Functions:

    - lambda arguments: expression

15. Virtual Environments:

    - venv module for isolated environments

16. Modules and Packages:

    - Create and import custom modules

    - Organize code into packages

17. Python 3 vs. Python 2:

    - Differences and migration considerations

18. Helpful Libraries:

    - NumPy (numerical computing)

    - pandas (data analysis)

    - Matplotlib (data visualization)

    - requests (HTTP requests)
