Variable/Name
< Variable
Different languages have different naming conventions for variables. Of note:
- C and related languages tend to use [_a-zA-Z][_a-zA-Z0-9]*
- Python is the same as C except it allows unicode letters.
- Lisp-like languages allow a much broader range of variable names, including most symbols.
Regardless of what the language allows, there is generally a convention on what names mean.
- Some programming styles include information about the variable type in its name.
- Some programming styles name certain kinds of variables differently than others, especially depending on scope. (ALL_CAPS for global config, StudlyCaps for class names, etc...)
- Some programming styles reserve certain keywords for certain kinds of variables. (has_X, is_X, x?, etc...)
