100 Exercises - The Python Programmer Course

This repository contains exercises for the Udemy course The Python Programmer designed and maintained by Shehab Abdel-Salam.

The course is divided into chapters, each containing exercises and tests. The exercises are designed to help students practice Python programming concepts, while the tests are used to verify the correctness of their solutions.

1. Structure

The repository has the following structure:

├── chapters/
│   ├── chapter1/
│   │   ├── exercises/
│   │   │   ├── exercise_ch1_01.py
│   │   │   ├── exercise_ch1_02.py
│   │   │   └── ...
│   │   └── tests/
│   │       └── test_ch01.py
│   ├── chapter2/
│   │   ├── exercises/
│   │   │   ├── exercise_ch2_01.py
│   │   │   ├── exercise_ch2_02.py
│   │   │   └── ...
│   │   └── tests/
│   │       └── test_ch02.py
│   └── ...
├── ninja_challenges/
│   ├── exercises/
│   │   ├── challenge_01.py
│   │   ├── challenge_02.py
│   │   └── ...
│   └── tests/
│       └── test_ninja_challenges.py

The chapters directory contains subdirectories for each chapter in the course. Each chapter directory contains an exercises directory for the exercises, a tests directory for the tests, and a main.py file for testing your code.

The ninja_challenges directory contains additional challenges for you to practice more once you complete the course. It also has an exercises directory for the challenges and a tests directory for the tests.

2. Getting Started

2.1 Prerequisites

Before you begin, ensure you have the following installed on your machine:

  • Python 3.12 or higher
  • pip package manager
  • pytest testing framework

To check if you have Python installed, run the following command in your terminal:

python --version

If you get a command not found: python, you can download and install Python from the official website: Python Downloads

To check if you have pip installed, run the following command in your terminal:

pip --version

If you get a command not found: pip, you can install pip by following the instructions on the official website: Installing pip

To install pytest, run the following command in your terminal:

pip install pytest

This will install the latest version of pytest on your machine.

This repository was last tested with pytest version 8.3.2.

Note that you may need to use pip3 instead of pip depending on your Python installation.

2.2 Setup

First, make sure to clone the repository to your local machine using the following command:

git clone https://github.com/shehab-as/The-Python-Programmer.git

Afterwards, navigate to the repository directory:

cd The-Python-Programmer/

2.3 Running the Exercises

  1. Navigate to the chapter you are working on:

    cd chapters/chapter01_intro

  2. Edit the main.py file to write your solution or test your code.

    python main.py

  3. Write your solution in the corresponding exercise file. For example, if you are working on exercise 1 in chapter 1, you should write your solution in the exercise_00.py file.

  4. Run the test to verify the correctness of your solution.

    Note: Always use the -k flag to run a specific test.

    pytest -k e00
    Click to see the following output if the test fails: 
    tests/test_ch01.py:5: AssertionError
=========================================== short test summary info ===========================================
FAILED tests/test_ch01.py::test_e00 - AssertionError: assert 'I am ready to learn ______!' == 'I am ready to learn Python!'
=========================================== 1 failed in 0.01s ===========================================
    Click to see the following output if the test passes: 
    tests/test_ch_01.py .                                                                                [100%]

=========================================== 1 passed in 0.01s =============================================

    Optional: You can run all the tests for the chapter you are currently working on:

    pytest tests/

  5. If the test fails, you will see an error message indicating the reason for the failure. Fix the issue in your code and run the test again.

  6. Repeat steps 2-5 for each exercise in the chapter.

  7. Once you have completed all the exercises in the chapter, you can move on to the next chapter and repeat the process.

    cd ../chapter02_variables

3. [Optional] Running the Ninja Challenges

Problems are inspired by EPI book and LeetCode.

  1. Navigate to the ninja challenges directory:

    cd ninja_challenges/

  2. Edit the main.py file to write your solution or test your code.

    python main.py

  3. Run the test to verify the correctness of your solution.

    Note: Always use the -k flag to run a specific test.

    pytest -k challenge_01
