ReviewPart 1: modules 1-6Kylie McCollToday

Review questions from topics 1-6:

Computers, algorithms, programs, and Python

I/O, Variables and expressions

Conditionals

Sequences

Functions

Iteration

ConceptsTo solve problems computationally requires:

A “Computer”

An Algorithm

An executable program

Python is:

A high-level programming language (closer to natural language than machine code)

an?interpreted language?as implementations execute instructions without previously?compiling?a program into machine-language?instructions

Concepts continuedPython programs perform calulations using expressions

Functions are mini-programs, and Python programs are built from many functions

Python programs must be readabile as well as correct, so that they can be used by other programmers

Python programs should be documented so that they can be used by other programmers

Errors occur when a Python program isn’t written correctly (syntax errors), or when it is written correctly but the instructions can’t be completed (runtime errors)

Even when error-free, Python programs may not produce the correct output (logic errors); in either case, we can use systematic strategies for finding and removing bugs from our Python programs

ConceptsInput and print functions

Check understanding of these in-built functions. Common errors: f-strings for formatting string literals

Variables and data types
