Syntax confusion (EACH / FOR)

In this video, the instructor first start with:

each key in list

Thank copy and paste a more robust code with:

for key in list

In the quiz at the end of this lesson there is a question that put both syntax as possible answers.

I chose EACH and it was correct. But what about FOR? It worked in his example.

Both FOR and EACH are valid. I took the quiz twice and the first time I chose EACH, like you, and got it right. The second time, I chose FOR and also got it right. I don't know why there are two keywords for the same operation, but they are both syntacticly valid.

I hope this helps. Let me know if there is anything else I can do.
