_ (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()

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).
