Underscore alone is a special variable name and I’m pretty sure anything assigned to it goes straight to garbage collection. Whereas _myvariable is typically use to indicate a “private” class variable or method (Python doesn’t have private so it’s just a convention).
In Python you can use this as a variable name
In Python you can use 🍆 as a variable name.

The source character set is implementation defined.
You can use anything that doesn’t start with a digit or punctuation as a variable name (underscore beginning also allowed) unless it’s a keyword.
_ (sic) as a variable name is often used when a function returns multiple outputs but you only want one
