    _ (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).
