Rustom, did you not notice that the OP seemed to understood the 'for' perfectly
well, but asked what the meaning of the [ ] delimiters is? He explicitly says:
"what [] means in this statement?"
and it's the subject of the thread! Apart from your own bias against explicit
for loops, what made you think that the OP understood the [] but was confused
by the "for" when he explicitly said the opposite?

You have no evidence at all that the OP knows set builder syntax. Most people
don't.
