The notation here suggests Ron is sligtly confused about what he
created. It was equivalent to

string_ = "%d event%s" % (num, lambda x: x > 1 and "s" or "")

Notice that there's no actual mention of num there, it's a function that
takes one parameter. If that parameter happens to be num it does what
you want, but there's no way for the interpreter to know what was
intended.
