define code readability

ensuring any code written is easy to read and understand it is necessary as programmers usually work in teams with each programmer developing a different part of the program. This only works if they adopt a standard approach to writing readable code

what are the 4 techniques to improve code readability

comments: used to explain what each part of the program does

descriptive names: using descriptive identifiers for variables, constants and sub programs helps to make their purpose clear

indentation: makes it easier to see where each block of code starts and finishes. Getting indentation wrong in python will lead to program not running or not producing expected outcomes

white space: adding blank lines between different blocks of code makes them stand out

define block of code

a grouping of two or more code statements

how to write comments in python
