In this lesson you will meet the core building blocks that every AI practitioner uses daily: variables, data types, lists, dictionaries, loops, functions, and essential libraries. You will understand enough to read AI code without fear and write small programs that actually run — all in a free browser tool, no installation required.","outcomes":["Write and run Python code using variables, lists, and dictionaries","Use loops and conditionals to process data","Define and call functions with docstrings","Import and use external libraries like NumPy"],"narration":"Welcome to Introduction to Python for AI. By the end of this lesson, you'll be able to write and understand basic Python code used in AI workflows. Let's get started."},{"kind":"content","heading":"Why Python for AI?","body":"Python dominates AI because of its clear syntax and vast ecosystem. The most important tools — NumPy (fast maths on arrays), pandas (data tables), and AI SDKs like openai and anthropic — are all Python-first.\n\nAnalogy: Think of Python as a well-stocked kitchen. The language itself is the stove and worktop; the libraries are pre-made sauces and spice mixes. You rarely cook from scratch — you combine trusted ingredients.\n\nTo use external libraries, you first need to install them. Python comes with a package manager called pip. For example, to install NumPy, run:\n

bash\npip install numpy\n

\nIt's also good practice to use virtual environments to keep project dependencies separate. Create one with:\n

bash\npython -m venv myenv\nsource myenv/bin/activate  # On Windows: myenv\\Scripts\\activate\n

\nThen install packages inside it. This avoids conflicts between projects.","callout":{"variant":"note","title":"Installing Packages","text":"NumPy is not built into Python. You must install it with pip install numpy. Always use a virtual environment to manage dependencies."},"narration":"Python is the go-to language for AI because of its readability and powerful libraries. To use libraries like NumPy, you need to install them with pip, and it's best to work inside a virtual environment."},{"kind":"content","heading":"Variables and Data Types","body":"A variable is a labelled box that stores a value. Python figures out the type automatically.\n\n

python\nname = \"Amara\"        # str  (text)\nage = 29              # int  (whole number)\nhourly_rate = 12.5    # float (decimal)\nis_student = True     # bool  (True/False)\n\nprint(f\"{name} is {age} years old.\")\n

\n\nThe f before the string makes it an f-string, letting you embed variables inside {}. This is the standard way to build text in modern Python.","narration":"Variables store data. Python automatically determines the type. F-strings make it easy to combine text and variables."},{"kind":"content","heading":"Collections: Lists and Dictionaries","body":"A list is an ordered, changeable collection. A dictionary stores key-value pairs — like a labelled record.\n\n

python\nskills = [\"Python\", \"data\", \"AI\"]\nskills.append(\"prompting\")\nprint(skills[0])  # \"Python\"\n\nlearner = {\n    \"name\": \"Wei\",\n    \"country\": \"Singapore\",\n    \"level\": \"beginner\",\n}\nprint(learner[\"country\"])  # \"Singapore\"\n

\n\nDictionaries are crucial in AI because API responses and configuration data often come as JSON, which Python represents as dictionaries.","narration":"Lists hold ordered items; dictionaries store labelled data. Both are essential for handling AI data."},{"kind":"content","heading":"Loops, Conditionals, and Functions","body":"Loops repeat actions; if-statements make decisions. Functions are reusable blocks of code.\n\n

python\nscores = [85, 42, 91, 60]\nfor score in scores:\n    if score >= 60:\n        print(f\"{score}: pass\")\n    else:\n        print(f\"{score}: revise\")\n\ndef average(numbers):\n    \"\"\"Return the mean of a list of numbers.\"\"\"\n    return sum(numbers) / len(numbers)\n\nprint(average(scores))  # 69.5\n

\n\nIndentation (4 spaces) defines code blocks in Python. Docstrings (triple quotes) describe functions — writing clear docstrings helps AI assistants generate better code.","callout":{"variant":"tip","title":"Indentation Matters","text":"Python uses indentation to group statements. Always use 4 spaces consistently. Mixing tabs and spaces causes errors."},"narration":"Loops and conditionals control the flow of your program. Functions let you reuse code. Remember to indent properly."},{"kind":"content","heading":"Real-World Examples","body":"Here are three concrete examples of Python basics in action:\n\n- Market trader in Lagos, Nigeria: Uses a few lines of pandas to read a CSV of daily sales, group by product, and find top earners — replacing an hour of manual work.\n- Nursing student in the Philippines: Writes a Python function to convert temperatures between Celsius and Fahrenheit, then loops over a list to flag unsafe readings.\n- Startup in Berlin, Germany: Uses Python with the anthropic SDK to send customer emails to Claude for summarisation, storing results in dictionaries before saving to a database.\n\nThese examples show that the basics you're learning are exactly what professionals use daily.","narration":"Python basics are used everywhere — from market analysis in Lagos to patient monitoring in the Philippines to AI integration in Berlin."},{"kind":"quiz","heading":"Check Your Understanding","questions":[{"question":"Which of the following is the correct way to install the NumPy library?","options":["import numpy","pip install numpy","numpy install","install numpy"],"questionId":"cmrf73k9d0021pd276fenw6uc"},{"question":"What will the following code print?\n\n
