I'm not picking on your specific example. I am only pointing out that Python gives you the tools you need to build nice APIs. If repetition is an important part of something you're working on, then consider using itertools.repeat, writing your own domain-specific repeat() method, or even override * like list() does. One of the coolest aspects of Python is how a relatively small set of abstractions can be combined to create lots of useful behaviors.
For students, the lack of a "repeat" block might be confusing at first, but once the student understands for loops in general, it's an easy mental jump from "using the loop variable in the body" to "not using the loop variable in the body" to "underscore is the convention for an unused loop variable". In the long run, having one syntax that does many things is simpler than having many syntaxes that each do one little thing. +1 I would add that it is even the convention for all unused variables, not only in loops, as it is also used in other cases, like this for example : key, _, value = "foo:date:bar".split(":")
