What are the best practices for naming variables in Python?
When naming variables in Python, it's important to use descriptive names, follow the PEP 8 style guide, and use lowercase letters with underscores for readability.
Can you give me examples of good variable names?
Sure! Good variable names include user_age
, total_price
, and is_active
. They clearly describe the data they hold.
What should I avoid when naming variables?
Avoid using single-letter names (except for counters), reserved keywords, and names that are too generic like data
or temp
.
Is there a limit to how long a variable name can be?
While Python doesn't enforce a strict limit, it's best to keep variable names concise and meaningful, ideally under 79 characters.
