+PEP 515: Underscores in Numeric Literals
+========================================
+
+Prior to PEP 515, there was no support for writing long numeric
+literals with some form of separator to improve readability. For
+instance, how big is ``1000000000000000```? With :pep:`515`, though,
+you can use underscores to separate digits as desired to make numeric
+literals easier to read: ``1_000_000_000_000_000``. Underscores can be
+used with other numeric literals beyond integers, e.g.
+``0x_FF_FF_FF_FF``.
+
+Single underscores are allowed between digits and after any base
+specifier. More than a single underscore in a row, leading, or
+trailing underscores are not allowed.
