What is the variable naming convention in Python?

In Python, variable names must adhere to the following conventions:

  1. Variable names can only contain letters (a-z, A-Z), numbers (0-9), and underscores (_).
  2. Variable names cannot start with a number.
  3. Variable names are case-sensitive.
  4. Variable names should be descriptive so that the meaning of the variable is understood when reading the code.
  5. Avoid using Python keywords (such as if, for, while, etc.) as variable names.
  6. Improve the readability of variable names by separating words with underscores, such as “my_variable”.
  7. Avoid using single characters as variable names as much as possible, unless in specific cases such as loop variables like “i.”
  8. Variable names should be concise and descriptive, avoiding overly long or complex names whenever possible.

Here are some good examples of variable naming:

my_variable = 10
name = "Alice"
is_valid = True
count_of_students = 50

Following good variable naming conventions can improve the readability and maintainability of the code, making it easier for others to understand and use your code.
