Maintainability

A program is maintainable if it is easy to understand and modify the code even for someone that is unfamiliar with the code base.

Avoid the following anti-patterns to increase maintainability and avoid creating spaghetti code.

• using wildcard imports (from … import *)
• Not using with to open files
• Returning more than one variable type from function call
• Using the global statement
• Using single letter to name your variables
• Dynamically creating variable/method/function names
