High vs. Low Level Languages PYTHON IS A HIGH LEVEL LANGUAGE High Level Language Allows programmers to write algorithms, loops, and functions/methods without detailed knowledge of the hardware Examples: C, C++, Java, and Python Low Level Language Requires detailed knowledge of machine level coding: involvement with registers, interrupts, etc.. Example: MARIE Simulator www.michaelliut.ca/cs1md3
Functions vs. Methods A function is a piece of code that can pass data through it (in the form of a parameter) and can return data (optional). A method is a piece of code that is associated with an object defined in the class. Two key elements: A method is implicitly passed A method is able to operate on data contained within the class www.michaelliut.ca/cs1md3
Nested For Loop A for loop within a for loop Textbook pages 143-144 An inner loop enclosed inside an outer loop Textbook pages 143-144 Example Program www.michaelliut.ca/cs1md3
