Before You Build

2 quick questions. This is diagnostic only — it does not block the lesson.

1 / 4Core

What does json=payload do?

requests serializes the Python dictionary as JSON.

2 / 4Core

Why set a timeout?

A timeout bounds how long the client waits.

Mission

Send a Python HTTP request to local Ollama, inspect the JSON response, and recover from a stopped runtime.

Understand

Your program is now an API client: Python creates a JSON request, Ollama generates locally, and Python reads the JSON response.

Build

What you're doing

Create app/ask_ai.py, paste the client code, save it, and verify the file.

Why it matters

The file turns a Python dictionary into a real request to the local model API.

Create, open, paste, and save~/enjyra-free-ai/app/ask_ai.py

Where to work VS Code FileLanguage python

Create and open the fileRun this from ~/enjyra-free-ai.

mkdir -p app
touch app/ask_ai.py
code app/ask_ai.py

mkdir -p app
touch app/ask_ai.py
code app/ask_ai.py

New-Item -ItemType Directory -Force -Path "app" | Out-Null
if (-not (Test-Path "app\ask_ai.py")) { New-Item -ItemType File -Path "app\ask_ai.py" | Out-Null }
code "app\ask_ai.py"

Before You Run

Your terminal is open in ~/enjyra-free-ai.
Python 3 is installed; activate .venv first when the lesson has already created it.
Visual Studio Code is installed; the optional code shell command is available, or you can open the file manually.

Why You're Running This

app/ask_ai.py is the project’s python file at ~/enjyra-free-ai/app/ask_ai.py. It must exist before you can paste the supplied content. The commands create its folder when needed, create the file, and open it in VS Code; the next stage tells you what to paste and reminds you to save it.

Command Breakdown

mkdir -p / New-Item Directory: Creates the requested folder and any missing parent folders without failing when it already exists.
touch / New-Item File: Creates an empty file at the requested path without requiring code to exist first.
code: Opens the file or folder in Visual Studio Code from the terminal.

Expected Result

app/
└── ask_ai.py

app/ask_ai.py exists and is ready for the supplied content.

What Changed

Beforeapp/ask_ai.py may not exist yet, or may still contain its previous content.

Afterapp/ask_ai.py now exists in the lesson workspace and is ready for the next instruction.

Verify It

macOSls -l app/ask_ai.py

Linuxls -l app/ask_ai.py

Windows PowerShellGet-Item "app\ask_ai.py"

Confirm the file exists at the expected path.

If It Fails

Check that the terminal is in the lesson project, the path spelling is exact, and VS Code is installed. If the code command is unavailable, use File → Open Folder in VS Code.

If code is unavailable, open VS Code, choose File → Open Folder, select enjyra-free-ai, then create app/ask_ai.py in the Explorer.

Save before continuing: press Cmd + S on macOS or Ctrl + S on Linux and Windows.

Verify the saved fileThe command should print the content you just saved.

cat app/ask_ai.py

cat app/ask_ai.py

Get-Content "app\ask_ai.py"

Before You Run

Your terminal is open in ~/enjyra-free-ai.
Python 3 is installed; activate .venv first when the lesson has already created it.

Why You're Running This

Reading app/ask_ai.py back from disk proves that the python content was saved at the correct path, rather than remaining only in an unsaved editor tab.

Command Breakdown

cat / Get-Content: Reads the saved file and prints its contents so you can verify it.

Expected Result

The terminal prints the complete content you pasted into app/ask_ai.py.

What Changed

BeforeThe current state has not yet been checked.

AfterNo persistent state changed; the command printed evidence you can compare with the expected result.

Verify It

macOScat app/ask_ai.py

Linuxcat app/ask_ai.py

Windows PowerShellGet-Content "app\ask_ai.py"

Run the command and compare its output with the Expected Result block.

If It Fails

Save the file, confirm the filename and capitalisation, and check the current folder with pwd on macOS/Linux or Get-Location on Windows.

If it fails

Check that your terminal is in ~/enjyra-free-ai, the filename and capitalisation match exactly, and the file was saved. Use pwd on macOS/Linux or Get-Location on Windows to check your current folder.

What changed

app/ask_ai.py now exists in the project.

What you're doing

Create and activate a project virtual environment, then install requirements.txt.

Why it matters

An isolated environment keeps this project's packages predictable.

TerminalChoose macOS, Linux, Windows, or Explain

Where to run Terminal or VS Code TerminalWorking directory ~/enjyra-free-ai

What to run

Set-Location $HOME\enjyra-free-ai
py -m venv .venv
.\.venv\Scripts\Activate.ps1
py -m pip install -r requirements.txt

Before You Run

Your terminal is open in ~/enjyra-free-ai.
Python 3 is installed; activate .venv first when the lesson has already created it.

Why You're Running This

An isolated environment keeps this project’s Python packages separate from system Python and other projects.

Command Breakdown

cd / Set-Location: Changes the terminal’s current working directory before the next command runs.
python -m venv: Runs Python’s built-in virtual-environment module and creates an isolated environment, normally in .venv.
.: Runs the . tool with the shown arguments to complete this lesson step.
pip install: Installs the named Python packages into the active environment.
py: Runs the py tool with the shown arguments to complete this lesson step.
activate: Makes the project’s virtual environment the active Python environment for this terminal session.
&&: Runs the next command only when the previous command succeeds.

Expected Result

Successfully installed requests

The project virtual environment contains the pinned HTTP client.

What Changed

BeforeThe project does not yet have its own isolated Python environment.

AfterThe .venv folder contains an isolated Python interpreter and package directory.

Verify It

macOStest -d .venv && echo ".venv exists"

Linuxtest -d .venv && echo ".venv exists"

Windows PowerShellGet-Item .venv

Confirm the virtual-environment folder now exists.

If It Fails

No such file or directory → verify the current folder and the path spelling.
Permission denied → work inside your own lesson folder and confirm it is writable.

What you should see

Successfully installed requests

Success looks like: The project virtual environment contains the pinned HTTP client.

If it fails

command not found → verify the required tool is installed and reopen the terminal.
No such file or directory → check your current folder with pwd or Get-Location.
Permission denied → confirm the lesson workspace is writable.

What changed

.venv contains the pinned requests package.

What you're doing

Execute ask_ai.py from the activated environment.

Why it matters

This verifies Python can reach Ollama and read its JSON response.

Before You Run

Install Docker Desktop on macOS or Windows, or Docker Engine/Desktop using the official instructions for your Linux distribution. Start Docker and open Terminal or native Windows PowerShell.

Why Do We Need Docker?

The ENJYRA AWS, Azure, and GCP labs run locally inside Docker containers. No real AWS, Azure, or GCP account is required.

Command Breakdown

docker --version: Confirms the Docker command-line client is installed.
docker info: Asks the Docker Engine for server information, proving it is running and reachable.
docker run --rm hello-world: Runs a small official test container end to end and removes it when finished.

Expected Result

Docker version 2x.x.x
docker info: server details
Hello from Docker!

What Changed
