My Journey Through Learning Python

The primary purpose of this repository is to document my process of learning Python.

Within ../Modules there is a folder named PythonRepo. This folder houses each of my Python scripts. Each of these scripts is named to reflect the concept it demonstrates -- "hello_world.py" does as it describes, etc.

The basics:

Below is the order I suggest the basics should be experienced:

1. hello_world.py - Does what it says on the tin: greeting the world.

2. inputs.py - Demonstrates taking basic inputs from a user.

3. calculator.py - Demonstrates basic mathematical equations within Python.

4. functions.py - A brief introduction to functions.

5. exponent_function.py

6. f_strings.py - An alternate, concise way to insert variables into 'print' statements.

7. if_statements.py - Provides a basic example of 'if' & 'else' statements.

8. basic translator.py - Should you want to learn how to garble text, this is an example.

9. lists_and_tuples.py - This is a rudimentary example of how lists and tuples work.

10. for_loops.py - Basic iterative 'for' loops.

11. while_loops.py - Basic iterative functions using 'while' loops.

12. guessing_game.py - A concise demonstration of 'if', 'elif' (or 'if-else' statements), and user inputs in action.

13. two_dimensional_lists.py - A basic two-dimensional list, somewhat akin to a basic array.

14. dictionaries.py - Dictionaries, using keys and values.

15. for_while_else.py - Mixing 'for' 'while' loops and 'else' statements.

16. choose_your_own_adventure.py - A basic 'choose your own adventure' game.

17. lambda.py - A simple example of 'lambda' - an anonymous variable declared within an expression.

18. comprehensions.py - Using 'for' loops on the same line as the expression of variables.

19. lists_tuples_sets.py - Using the '.pop()' method on lists; using the 'slice' operator; introducing 'sets'; demonstrating 'enumerate' statements; and a brief introduction to the '.union()' method.

20. sort_by_key.py - Sorting dictionaries using keys, functions, and the '.sort()' method.

21. map_and_filter.py - Mapping values to other values and checking if the result of a function is true using 'lambda'.

22. args_kwargs.py - Using '*args' & '**kwargs' in functions and various expressions.

23. slots.py - A working slot machine, demonstrating various concepts used previously.

More niche concepts & tools:

Here you will find examples of some useful functions, statements, methods and such that I went out of my way to learn and tinker with. I don't consider any of these

1. Reading & writing files:

   • reading_files.py - Reading files into memory, to be used within the Python environment.

   • writing_appending_files.py - Writing to new files, overwriting and appending data to existing files.

2. Handling exceptions:

   • handling_exceptions.py - Exception handling using functions, 'except', 'try' and 'finally' statements.

3. Zipping and unpacking:

   • zipping.py - Zipping lists together using the 'zip()' method.

   • unpacking.py - Unpacking tuples, lists, dictionaries and strings using unpacking.

4. Itertools:

   • itertools_example.py - An example of how to use the 'itertools' module, which focuses on iterative functions.

5. Password manager:

   • password_manager.py - An example of a basic password manager - DO NOT USE THIS TO STORE ANY CREDENTIALS YOU CARE ABOUT.

Comprehensive examples:

This is where I provide more detailed examples of concepts requiring more time and effort for me to grasp fully.

Classes & Methods:

Instead of steadily becoming more functionally complex, or starting small, this section will begin with an 'info-dump' of sorts -- consider this a disclaimer.

1. Single-file examples:

   • oop_dog.py - This goes through the basics of classes, such as the '__init__' dunder method as well as the 'self' parameter.

   • oop_student.py - This demonstrates adding individual objects to multiple classes, interacting with each object's attributes, and some specifics around the types of methods present within classes.

   • oop_inheritance.py - Here is an introduction to the concepts of class inheritance and class attribute priority.

   • class_attributes.py - A brief example of how 'class methods' work; all class methods are methods of a class, but not all methods of a class are class methods.

   • static_methods.py - A very brief introduction to static methods within classes.

2. Multi-file examples (grouped accordingly):

   • Chef:

     • chef.py
     • chinese_chef.py
     • inheritance.py

   • Multi-class import:

     • multi_class_import.py
     • classes_objects.py
     • useful_tools.py

   • Multiple-choice:

     • multiple_choice.py
     • question.py
