We don't actually import this anywhere, and most of the functions in it are trivial - we even have a
popkey
function, although dictionaries have had a built-inpop()
method since Python 2.3.The only non-trivial bit is
map_method
function, which lets you do things likemap_method('upper', list_of_strings)
. But we're still not using it anywhere, and I suspect we'd now use a listcomp in most cases instead of that.
