Issue 29088: Inconsistent use of underscore in names that start with "is" (original) (raw)

Compare isinstance, issubclass, and islower to is_integer, is_fifo, and is_enabled. In Python 3.6, of all the names in the standard library starting with is, I count 69 names with the underscore and 91 without. It seems better to pick one way or the other and stick with it. I would recommend using the underscore, for legibility.
