Python Dictionaries — The Basics
Build a real mental model of Python dictionaries: key-value pairs, safe lookup with get, why a dict is shared by reference, iterating with items, dict comprehensions, and reaching into nested data.
Python Lists — The Basics
Build a real mental model of Python lists: 0-based indexing and slicing, why lists are mutable and shared by reference, how iteration leads to comprehensions, and the shared-row pitfall to steer around.
Python Loops — The Basics
Build a real mental model of Python loops: how the for loop walks any iterable without manual index work, when range() and while fit, how enumerate() hands you the index, and how break, continue and the loop else clause change the flow.
Python Strings — The Basics
Build a real mental model of Python strings: why they are immutable sequences, how indexing and slicing reach into them, how f-strings assemble them, and how the everyday methods each return a new string.
