What are the variable name naming rules in python

In Python, the naming rules of variable names need to follow the following rules:

1. The variable name can only contain letters (case), numbers, and underscores (_), and cannot contain spaces or other special characters.
2. The variable name must start with a letter or underscore, not a number.
3. Variable names are case sensitive, for example number and Number Is a different variable name.
4. Avoid using Python keywords (reserved words) as variable names, such as if 、 for 、 while Etc.
5. Try to choose descriptive variable names to better understand the meaning of the code.
6. Use a combination of lowercase letters and underscores to name variables, such as my_variable , which is a common practice in the Python community.

The following are some examples of variable naming:

 age = twenty-five name = "Alice" is_active = True total_score = ninety-five point five

In the above example, we used descriptive variable names and followed Python's naming rules. Please note that good naming habits can improve the readability and maintainability of code in programming. It is recommended to develop good naming habits.
