Maintainability

Maintainability is the ability of a program to be easily understood, updated, and modified.
It's important to ensure that code is maintainable so that other programmers can easily read, understand, and fix it.

Maintainabilty

Commenting
Code reviews
consistent naming conventions
modular design
Testing
Clear documentation

Copy pasting code
ignoring errors
outdated libraries
overly complex code
spaghetti code

Multiple Choice

We can make our code maintainable by...

• Follow best practices for coding style, organization, and documentation.
• Use complex algorithms for simple tasks to confuse others.
• Ignore coding standards and write code however you like.
• Avoid commenting on code to keep it clean and uncluttered.

Multiple Choice

We can add comments to our code which is ignored by python by using which symbol?

​Comparison of Syntax, Runtime, and Logic Errors

Aspect	Syntax Error	Runtime Error	Logic Error
When it Occurs	Before the program runs (during parsing or compilation)	While the program is running	The program runs without crashing, but the output is incorrect or unexpected
Nature of Error	Relates to incorrect structure or grammar in the code	Occurs when valid syntax encounters issues during execution	Relates to incorrect logic or algorithm that leads to incorrect behavior or results
Can Program Run?	No, the program will not run until the syntax is corrected	Yes, the program starts running, but crashes at the point of error	Yes, the program runs to completion but produces the wrong result
Example	Missing : after an if statement	Dividing by zero (e.g., 10 / 0)	Using if a < b: when intending if a > b:
