when writing python code, choosing appropriate variable names is crucial for code readability and maintainability. in this tutorial, we'll explore the rules and best practices for naming variables in python, along with code examples to illustrate each concept.
do not use python reserved keywords as variable names, as they have special meanings in the language. examples of reserved keywords include if, else, while, for, import, etc.
choose meaningful and descriptive variable names that convey the purpose of the variable. this improves code readability and makes it easier for others (and future you) to understand the code.
use snake_case for variable names, where words are separated by underscores. this is a common convention in python.
for class names, use camelcase, where each word in the name starts with a capital letter. however, variable names still follow snake_case.
unless used as loop counters, try to avoid using single characters (e.g., a, b) as variable names. use names that provide more context.
for constants, use uppercase letters with underscores to separate words. this distinguishes constants from regular variables.
adhering to these variable naming rules and best practices will result in more readable and maintainable python code. remember to choose names that provide clarity and context to enhance the overall quality of your code.
