Learn to structure Go code into reusable pieces — functions with multiple returns, closures, variadics and defer, then packages and modules that organise and version your code. You will finish able to split a program into clean, importable packages and manage its dependencies with go modules.
Functions and modules are how Python programs stay small, readable and reusable instead of turning into one long, brittle script. This beginner course teaches you to define and call functions, pass default and keyword arguments, gather variable arguments with *args and **kwargs, document with docstrings, reason about scope, and import both standard-library and your own modules. It builds the function-and-module skills assessed by the Python Institute PCEP certification and finishes with a hands-on lab of ten programming exercises with full solutions.
Learn to build user interfaces from widgets in Flutter — the core skill every Flutter developer needs. You will compose screens from Text, Image, Icon and Container, arrange them with Row, Column, Stack, Expanded and Padding, choose between Material and Cupertino, and factor your UI into clean, reusable custom widgets driven by the build method.
Take a working web app from your laptop and host it end to end on a real Linux VPS — behind Nginx as a reverse proxy, kept alive by a process manager, reachable on your own domain over HTTPS. You will finish able to provision a server, deploy a Node or Python app, and run it in production with proper config and logs.
Learn to design well-structured PostgreSQL tables: pick the right data type for every column, model relationships correctly, and enforce data quality with keys and constraints. You will finish able to translate a real-world requirement into a clean, normalised schema that keeps bad data out.
Turn raw, messy data into clean, model-ready features using pandas and scikit-learn. You will clean and impute data, encode categoricals, scale numerics, handle outliers, engineer and select features, and assemble it all into a leak-free ColumnTransformer pipeline you can trust on unseen data.
Program confidently in Dart — the language behind Flutter. You will master variables and types, sound null safety, functions, collections, control flow, classes and async/await, so you can read and write real Dart code and use the Dart tooling with confidence.
Master Node.js core modules to read, write and process files and system resources with confidence. You will use fs, path, os, process and url, handle text and JSON safely, react to events with EventEmitter, and stream large files without exhausting memory.
Learn how Python makes decisions and repeats work using if/elif/else, truthiness, while and for loops, range(), and loop control with break, continue and pass. This beginner course builds the control-flow fluency the Python Institute PCEP exam expects, through runnable examples and a hands-on lab.
Understand what the cloud really is — on-demand computing you rent by the second — and how the service models, deployment models and shared-responsibility model fit together. Walk away able to choose the right cloud service model (IaaS, PaaS or SaaS) for a given workload and justify the choice on cost, control and responsibility.
Build a working REST API in Node.js from the ground up: start with the core http module, then move to Express to route requests, parse JSON bodies and return correct status codes. You will finish able to design and ship a full CRUD API over an in-memory store.
Learn to work confidently with Git branches — understanding them as lightweight movable pointers, creating and switching between them, and merging your work back together. You will resolve merge conflicts calmly, choose between rebase and merge, stash work in progress, and cut tagged releases, so you can honestly say you work confidently with branches on any team.
