choosing meaningful and consistent variable names is a crucial aspect of writing clean and maintainable python code. good variable names enhance the readability of your code, making it easier for others (and yourself) to understand the purpose and functionality of your program. in this tutorial, we'll discuss best practices for naming variables in python, along with code examples.
choose names that clearly convey the purpose of the variable. avoid generic names like temp, data, or single-letter names like x, unless they are used in a very localized context, such as loop counters.
