Yes, variable names in Python can start with an underscore. In fact, starting a variable name with an underscore is a common practice to indicate that the variable is intended for internal use or is a private variable.
Examples:
# Valid variable names starting with an underscore
_private_variable = 10
_variable_name = "Hello"
Important Notes:
- While starting a variable name with an underscore is valid, it is a convention that suggests the variable is meant for internal use and should not be accessed directly from outside the class or module.
- Python does not enforce access restrictions based on underscores, but it is a guideline followed by developers.
Summary:
You can use underscores at the beginning of variable names, and it is often used to indicate that the variable is intended for internal use.
