    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

       def my_function:
      return 1, 2, 3

 _, two, _ = my_function()

        _ can also be used in the python interactive terminal to mean ‘last return value’

        Ie:

        > 'string'
'string'
> a = _
> print(a)
string

        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 used to indicate a “private” class variable or method (Python doesn’t have private so it’s just a convention).
